Learnin’ ’bout ‘lectricity with Andy Tubbs

Originally posted January 18, 2013:

The day I became an electrician at the coal-fired power plant, I suddenly became an expert in electricity. I think it was on Tuesday, just one day after joining the electric shop that I was walking through the welding shop when someone stopped me and asked me how they would wire their living room with different light switches at different corners and make it work correctly. As if I had been an electrician for years. Luckily I was just finishing a house wiring course at the Indian Meridian Vo-Tech in Stillwater, Oklahoma and they had us figure out problems just like those.

Within the first week, George Alley brought a ceiling fan to the shop that he had picked up somewhere and was wondering if we could get it to work. My foreman Charles Foster thought it would be a good small project for me to work on to help me learn about electrical circuits.

After all, this ceiling fan could go slow, medium and fast, and it could go forward or reverse. Only at the moment, all it would do was sit there and hum when you hooked up the power. — So that was my first “unofficial” project, since the main goal was to make George happy so that he would help us out when we needed something special from the mechanics.

When I was a janitor, I had observed the electricians preparing to go to work in the morning, and often, one of them would go to the print cabinets at one end of the shop and pull out a blueprint and lay it across the work table and study it for a while. Then they would either put it back or fold it and put it in their tool bucket and head out the door to go do a job. Now, it was my turn.

Andy Tubbs was one of the two people that played the best jokes on me when I was a janitor. Larry Burns was the other person, and he was the person I was replacing as he had moved to another plant. Andy was the one that had taken the handle off of my push broom the moment I had my back turned so that when I turned around to grab my broom, only the broom head was on the floor, while the broom handle was across the counter by the lab, and Andy was across the other side of the room trying to act like he wasn’t paying attention, but with an expression like he had just played a darn good joke. — I actually had to go back into the bathroom I was cleaning so that I could laugh out loud. I was really impressed by Andy’s ability to play a good joke.

While I’m on the subject, shortly after I became an electrician, I was sitting in the electric shop office talking to Charles when he stopped and said, “Wait…. Listen….” We paused, waiting for something…. A few seconds later, the sound of a hoot owl came over the PA system (what we called the “Gray Phone”). Charles said, It’s an interesting coincidence that the only time the perfect sound of a hoot owl comes over the Gray Phone is when Andy Tubbs is riding in an elevator by himself or with a close friend.

I had been sent with Andy Tubbs and Diana Lucas (later Diana Brien), to go to the coal yard and figure out why some circuit for the train gate was not working. Andy had pulled out the blueprints and was studying them. I came up alongside him and looked at all the blue lines running here and there with circles with letters and numbers, and what I recognized as open and closed switches….

Andy stopped and gave me a momentary lecture on the nature of electricity. It was so perfectly summed up, that for years whenever I thought about the nature of electricity, I always began with remembering what Andy told me. He said this:

“Think of electricity like water in a hose. Voltage is the water pressure. Amperage is the amount of water going through the hose. You can have the nozzle on the end of the hose shut off so that no water is coming out and then you have no amperage, but you will still have the pressure as long as it is turned on at the source so you will still have voltage.”

“In these diagrams, you just have to figure out how the water is going to get from one side to the other. These circles are things like relays or lights or motors. When the electricity makes it through them, they turn on as long as the electricity can make it all the way to the other side.”

That was it! That was my lesson in ‘lectricity. All I needed to know. The blueprints were big puzzles. I loved working puzzles. You just had to figure out how you were going to get something to run, and that meant that certain relays had to pickup to close switches that might pick up other relays to close other switches. I found that most of the electricians in the shop were good at working all sorts of puzzles.

Andy went to the cabinet and grabbed one of the Simpson multimeters and a handset for a telephone that had red and black wires wrapped around it.

A telephone handset that looked like this, only it had a battery taped to it, and two leads coming out the bottom

I was puzzled by this at first. I thought I would just wait to see what we did with it instead of ask what it was for. We grabbed our tool buckets (which also doubled as a stool and tripled as a trash can as needed), and put them in the substation truck. The other truck was being manned by the designated electrician truck driver for that week. We needed a truck that we could drive around in without having to hold up the truck driver.

We drove to the coalyard and went into the dumper switchgear. Andy and Diane opened up a large junction box that was full of terminal blocks with wires going every which way in an orderly fashion. They located a couple of wires, and Andy unwrapped the wires from the handset while Diane removed the screws holding the wires to the terminal block. Then Andy clipped one wire from the telephone handset to each of the two wires and handed me the phone.

Diane told me that they were going to drive down toward the train gate where the railroad tracks come into the plant and try to find these wires on the other end. So, what they needed me to do was to talk on the phone so when they find my voice, they will know that they have the right wires. Diane said, “Just say anything.” Then they left the switchgear and I could hear them drive away in the truck.

Well. This was my opportunity to just talk to no one for a while without interruption. How many times do you get to do that in one day? Probably only when you are on the way to work and back again if you aren’t carpooling with anyone. Or you’re sittin’ on your “thinkin’ chair” in a single occupant restroom. So, I just kicked into Ramblin’ Ann mode and let myself go. I believe my monologue went something like this:

“The other day I was walking through a field, and who should I run across, but my old friend Fred. I said, ‘Well, Hi Fred, how is it going?’ and Fred told me that he was doing just fine, but that he had lost his cow and was wondering if I could help him look for it. I told him I couldn’t right now because I was helping some people find a wire at the moment, and if I became distracted, we might not only lose the cow, but we might lose the wires as well, so I better just keep on talking so that my friends on the other end can find the wires they are looking for. After that I went to the store and I picked up three cans of peas. I thought about getting four cans of peas but settled on three and brought them to the checkout counter, and while I was waiting in line I noticed that the little boy in front of me with his mom was looking at me as if he wanted to have one of my cans of peas, so I quickly made it clear to him that I was buying these cans of peas for myself by sliding them further away from him and glaring at him. Luckily the boy wasn’t persistent otherwise I would have broken down and given him a can of peas because he was looking kind of hungry and I was feeling sorry for him, though, I didn’t want him to know how I was feeling, so I put on a grim expression….”

Needless to say… My monologue went on for another 15 minutes. Yes… .15 minutes. I had expected Andy and Diane to have returned earlier, but I didn’t know how hard it was going to be to find the other end of the wires, so I just kept on ramblin’ to the best of my ability. It’s like what it says in the Bible. If we wrote down everything I said, it would have filled many volumes. Being a Disciple of Ramblin’ Ann came in handy that day. For more about Ramblin’ Ann, you can read the following post:

Ed Shiever Trapped in a Confined Space With A Disciple of Ramblin’ Ann

When Andy and Diane returned they said that they had found the wires right away, but that they had sat there for a while just listening to me ramble. They said I was cracking them up. They also mentioned that they thought I was completely crazy. Well. I was glad that they found the wires and that my rambling abilities had come in handy.

Five months after I had joined the electric shop, Andy and I were sent to Oklahoma City to learn about a new kind of electric troubleshooting. It was called “Digital Electronics”. I had just finished my electronics class at the Vo-Tech, and so I was eager to put it into practice. Andy and I went to a two day seminar where we learned to troubleshoot what was basically a PC motherboard of 1984. We used a special tool called a digital probe and learned how the processor worked with the memory chips and the bios. It wasn’t like a motherboard is today. It was simple.

It was just designed for the class so that we could use the digital probe to follow the different leads from the chips as the electric pulses turned on and off.

We were using digital probes similar to this

At the time I was thinking that this was a waste of time. I had been learning all about troubleshooting electronic circuits from Bill Rivers and Sonny Kendrick. I couldn’t see how this was going to be useful. I didn’t know that within a couple of years, most of our electronic circuits in the precipitator controls were all going to be replaced with digital controls, and this was exactly what I was going to need to know.

So, Andy and I spent two days learning all the basics of how new computers were going to be working. This was the same year that Michael Dell was beginning his new computer company further down I-35 in Austin Texas. Who would have thought that 18 years later I would be working for Dell. But that’s another lifetime away…

Early in my career at the Seminole Plant I learned when someone paged you on the gray phone, you should always check the earpiece of the phone before you put it on your ear – it might be full of clear silicone calk (or worse). Also, at the end of the day when you reach to pick up your lunch box, you should pick it up gently. Someone could have slipped a full bottle of mercury (like 20 pounds) in it. This prevents you from pulling the handle off your lunch box or hearing it crash to the floor, smashing everything in its path. It’s amazing what Power Plant Men are capable of doing.

    We used hand lotion in the electric shop for the gray phone trick. I remember Andy catching an unsuspecting operator in the main switchgear more than once.

Working Smarter with Power Plant Dumb Terminals

Originally posted January 3, 2014:

After the reorganization at the coal-fired power plant in North Central Oklahoma during 1987, a bunch of new faces showed up at the plant.  I mentioned in last week’s post that we had a new plant manager, Ron Kilman (See Post:  “From Pioneers to Power Plant Managers“).  In that post I also mentioned that the PC age was rapidly growing and I had bought a computer of my own and was eager to learn more.  The Electrical Supervisor, Leroy Godfrey had retired, and was replaced by a guy named Tom Gibson.  Tom was a good supervisor who was willing to think out of the box.

Tom gave me one of my first assignments directly by calling me to his office.  Well, Leroy had never really called me to his office before.  When Leroy wanted to chew you out, he was happy to come down to the Electric Shop and do it, so I didn’t really know what to expect by being “called to his office”.  Believe me… it wasn’t the last time he had “called me to his office.”  But it was the most satisfying time.  Mainly because this time, when I arrived, Tom’s face wasn’t beet red with anger like it was on one later occasion.

This is what Tom told me to do…  He said that we needed to install computer terminals all over the plant.  They had a chart where they wanted the terminals to go.  There were about 15 locations all over the plant including the coalyard which was about 1/2 mile from the main plant.  Along with those, there were a bunch of IBM Network printers that needed to be installed with the terminals.

Then Tom told me the best part.  He wanted me to do it all myself.  Then he told me an even better part…. He said, (and I quote) “I want you to learn everything you can about this computer stuff.  I think it will come in handy.”  As my friend Stephen Todd at Dell would say, “That was the ‘Keys to the Kingdom”.  I told him I would be glad to do everything he asked.

That last part later came back to haunt Tom…. but he did tell me…. learn “everything” I could about the computer.  When he was referring to “The Computer”, he was talking about the company mainframe, a Honeywell system that resided in Oklahoma City at Corporate Headquarters.

The Terminals I was going to install were called “Dumb terminals”.  they weren’t computers, they were just monitors with a keyboard that connected directly to a switch back in the telephone room that was connected via a microwave link directly to Oklahoma City and the Honeywell system:

A DEC terminal like this.

A DEC terminal like this.

So, when I returned to the electric shop, I began my “hacker” apprenticeship.  One that would later allow me to harass Gene Day in the Control Room, confuse Dick Dale in the warehouse, cause headaches for the IT department downtown, and finally cause the President of the Electric Company to personally call our Plant Manager Ron asking who was this guy Kevin Breazile!  Hence the reason for Tom Gibson’s beet red face a few years later.  But that is another story for another time.

I had two things right away that I had to figure out.  How was I going to run cables from the telephone room in the office to each of the places around the plant that needed a computer terminal and what are these funny connectors and what do I need to do with them?

A Modular DB25M to RJ45 Adapter

Ok, so I figured they plugged in the back of the terminal and then there was a Cat1 cable (no, not a Cat3, a Cat1) that plugged into that, and needed to plug into a jack in the wall that I was going to have to install.  They called these funny connectors “Hoods”.  The 25 pin Hoods that we used were blue.  We had 9 pin hoods also that we used for the actual PCs that the clerks and the chemist were using.  They had an emulator program to make them act like a dumb terminal:

 A Serial RS232-DB9 9-Pin Female to RJ45 Adapter

In an early post called “Power Plant Men’s Club Prizes and a Story of Luck” I explained how I have always been cursed with being very lucky.  Well, that’s what some may call it, but I prefer to believe that one of my best friends St. Anthony helps me out at certain times.  Well, this was one time when I asked for his assistance.  St. Anthony of Padua is considered the Patron Saint of lost items.  So, I asked him to help me figure out how I was going to do all this work in a reasonable amount of time.

St. Anthony of Padua

As is often the case, St. Anthony pointed me in the right direction.  This particular day, he told me to tell my problem to Charles Foster.  My close friend and one of the two Electric Shop foremen (not mine.  I was working for Andy Tubbs).  So, during lunch I told him what Tom Gibson told me to do, and showed him the blueprints where they wanted the terminals placed throughout the plant.

One of the places that needed a terminal was right there in the electric shop office.  Charles looked around the office and said, “You know what?  there used to be an old intercom system in this office that I think goes up to the telephone room.  In fact, I think all the intercoms that were originally installed in the plant went to the telephone room.”

An old intercom sort of like this only in a box that sat on the desk and it had more switches

An old intercom sort of like this only older and in a box that sat on the desk and it had more switches

I vaguely remembered the intercoms when I was working as a summer help as there used to be an old box sitting in the garage when I worked for Stanley Elmore.  They were later cut out and removed, because it wasn’t really practical and so it wasn’t used.  Charles told me to start there, because there were intercoms everywhere.  In the control room, the warehouse, and even in the coalyard!  And definitely in the office area.  This was just what I needed to hear.  My work was already half done.

I pulled the cables out from under the desk where they had been cut and checked them out.  There were definitely enough cable pairs to do the job.  In most places I had to install both a terminal and a printer, so I had a lot of dual wall jacks just for this job:

A dual RJ45 Wall Jack

A dual RJ45 Wall Jack

There were some places where the intercom system didn’t go where I needed to install either a dumb terminal or at least connect a computer.  So, I was looking for any kind of alternate way to install the jack without having to run cables all the way from the telephone room to these locations.  So, I went out and bought a book about networking so that I could learn more about what was really going on.  If I had bought it a few years later it might have been called “Dumb Terminals for Dummies”, but the Dummies books hadn’t come around yet.

I have since thrown that book away after using it for years to prop up the corner of our sofa bed for the times when my mom would come and visit and she would sleep on the bed, only it had a broken bracket, and the Networking book was just the right thickness to level the bed…. But there was one page in the book that I found that allowed me to hook up dumb terminals in places where there was only a phone line.

You see.  When the phone lines were run throughout the plant, they used a three pair cable.  Well.  A phone really only uses two wires (or one pair).  so, this left 4 more wires not doing anything.  The only problem was that the dumb terminal used 4 pair, or 8 wires…

An RJ45 Cable

An RJ45 Cable has 8 wires

So, when I was reading the networking book, I ran across a diagram that made me stop and stare.  I like to think that I was holding a half eaten apple in my hand and I had just taken a bite when I stopped mid-bite and stared.  It would have been a nice picture to remember sort of like when the apple fell on Newton’s head.  Only we didn’t have cellphones with cameras in those days, so no one was around to take my picture.  The diagram I saw was this:

The pin configuration for an RJ45 connector

The pin configuration for an RJ45 connector

What?  This showed 4 of the wires are nothing but grounds….  The network cable only really uses 4 of the 8 wires.  Which means I only needed two pair.  And guess what?  The phone lines run all over the plant were 3 pair with only one pair being used!  So, I was able to install the computer jacks right next to the telephone jacks and use the same cable that the telephone was using, and they all tied back to the telephone room where the main computer switch was located that connected to the Mainframe computer back in Oklahoma City through something called a Memotec X.25 Modem.

So, now that I have gone through all this detail to tell you how I was able to quickly install all these terminals and printers around the plant in a way as if it is exciting (because it is to me).  I know that many of you are so bored out of your gourd that you have already stopped reading before you have reached this sentence….  I suppose those of you that are still following along are wondering “Why?”

Why would we want to install all these dumb terminals throughout a power plant that connected to the Honeywell Mainframe down at Corporate Headquarters?  Well.  It was because all the plant operators, mechanics, welders, machinists, electricians, instrument and controls and heavy equipment operators were going to start using it to do stuff.  Yeah.  All of us were being introduced to the computer age.  From the janitor on up.

Each printer had 4 character ID that identified it, so if you were looking at a work order on the terminal, you could choose to print it.  You just had to know the 4 character number and you could print the work order out on any computer in the company.  Usually, this meant, you wanted to use the printer that was closest to you.  But if you wanted to print something out for the warehouse, as long as you knew their printer ID, you could send them a printout of some part that you wanted them to retrieve for you.  Then call them up and tell them you printed something out on their printer.

Ok.  So the average Joe didn’t see much benefit, but it did get them used to seeing computer monitors all over the place, which at least helped them in the future when the real computers showed up.  Right now, they were just “Dumb Terminals” and that’s what a lot of the operators and maintenance people thought… they are just dumb…

I, on the other hand was in hog heaven.  You see.  I had called downtown to the IT department and asked to get a user name so that I could log directly into the mainframe.   After all, my supervisor Tom had told me to learn “everything” I could about “this computer”.  So, I took him up on it.  I quickly was learning UNIX commands, though at the time, I didn’t know that’s what they were called.

I began learning the Computer language called “A” before I realized there was a “B” language and a “C” language, and that C was the one that was really used at the time.  As it turned out the mainframe had manuals for everything right on it.  That is how I was able to cause so much trouble the next few years.

Oh, and one more interesting thing I discovered on the mainframe.  It had this interesting feature called “Email”.  Yeah.  Only, after figuring out how to pull up a list of all the emails on the system I found that there was only a handful of people that actually had e-mail addresses.  So, the only person I would email on the mainframe was an engineer named Craig Henry.

Craig Henry. Engineer and Gentleman

Craig Henry. Engineer and Gentleman

I had met him briefly once, but in the next few years, he was a valuable source of information.  Email seemed like a great idea, but what good was it if there was only a few people you could send an email?

As for Craig Henry… As Humphrey Bogart said to Claude Rains in Casablanca, “This is the beginning of a Beautiful Friendship.” Come to think of it… Craig Henry sort of reminds me of Claude Rains…  I must admit, I learned a lot more from him than he ever learned from me.

When Enough Power Plant Stuff Just Ain’t Enough

Originally posted March 21, 2014:

As a young novice Power Plant Summer Help, I had watched seasoned Power Plant Men measure the distance between two points by walking between them and multiplying the number of steps by three. At first I wondered how they could be sure that their strides were all exactly three feet apart. Because the end result of these actions usually came out pretty close to their estimate, over time I began to think that the length of the stride of any respectable Power Plant Man must naturally be three feet.

So, one day when I was working on going to pull a cable from one manhole to the next, I decided I wanted to know the distance before I pulled a lot of cable off of the cable reel. So, I remember that I grabbed the tape measure out of my tool bucket and began walking at as normal of a gait as I could.

I thought if I measured the first step, or even the last step I took that it would somehow be a different size because I wasn’t moving at my normal speed. So. I figured I would surprise myself by just stopping at some random step as I walked between the two manholes.

I don’t know if anyone was watching me as I stood out in the field just north of the two smokestacks, if they were watching me, then they would have seen me pause and stand still for a moment looking down. Start messing around with my feet. Then take a few more steps. Pause once more and do the same thing.

What I was doing was stopping in the middle of my stride when I had just put a foot down, before I lifted the other foot and with my Stanley metal tape measure, I was measuring the distance from the back of one heel to the back of the other heel.

I can’t say that I was too disappointed to find that my stride was not exactly three feet. I hadn’t figured I was completely Power Plant Man material anyway. It turned out to be exactly 30 inches. Or two and a half feet. So, I realized I was about 3/4 Power Plant Man measured by my stride.

I found that I could easily walk between two points and measure the distance with great accuracy by multiplying the number of steps by two and a half feet. With great knowledge comes great responsibility…. or…um… something like that. Hence the story about how enough was not quite enough.

During the spring of 1992 I was tasked with running telephone cable to various points around the plant. We were going to begin installing a new computer network known as the “Ethernet”. When I first heard the name, I thought they were referring to something in space, where it used to be the belief that there was an area called the “Ether”. But as it turned out, it was the regular network that is still in use today.

Dennis Dunkelgod from Oklahoma City had come to the plant with a bunch of drawing much like they did a few years earlier when they wanted me to install the Dumb Terminals all over the place. (See Post “Working Smarter with Power Plant Dumb Terminals“). This time the diagrams included places where PCs were going to be placed. And where the network server was going to be setup. This required much better quality wiring than the dumb terminals.

So, Dennis saw to it that I had 1/2 mile of 100 pair telephone cable to run from the main plant up to the coalyard. Along with the cable came a box of 25-pair punchdown blocks. I’m sure you’ve seen punchdown blocks in movies when someone is tapping into a phone line, so they go up to these punchdown blocks and hook their handset up to the wires and listen in.

One of the places where I needed to place a number of computers was in the warehouse and the warehouse office. There were no good phone lines running to this building. There were barely enough to take care of the phones that were in the office at the time. So, I needed to figure out how to run the telephone cable to the warehouse which was the southern-most building in the main plant grounds.

Across the drive from the warehouse was the garage. When I looked at the phone panel in the garage, this looked like a good place to tap into the phone system. There were two 25 pair blocks in this building for only one phone. Enough for all the computers in the garage and the warehouse.

All I needed to do now was figure out how to pull a 50 pair telephone cable from the garage over to the warehouse. After looking for the conduit that brought the existing cable into the garage, I was able to determine how it went over to a hand hole at the north corner of the building and then over to a manhole not far away.

A hand hole was a shallow hole in the ground that has buried conduit coming into it. Our handholes had a large piece of concrete covering it.

When I looked at the handhole I suddenly remembered that in during the week of March 21, 1981 I had visited the Power Plant to pick up my application to apply for working as a summer help for my 3rd summer. I was wearing a beard that day when I arrived. While I was in college, I usually wore a beard in the winter to keep my face warm because I rode my bike a lot, and it helped keep my face warm.

I had my friend Tim Flowers with me that day because he was going to apply to be a pre-novice Power Plant Man and work as a summer help also that summer. It was snowing that day and it was almost 4:30pm. Quittin’ Time by the time I had said hello to the many Power Plant Men that I hadn’t seen since the previous summer.

We were heading back out to the parking lot when I heard someone hollering at me. I looked over toward the garage and there was Jim Heflin sitting on a backhoe digging a ditch. He had turned off the backhoe so that I could hear him yelling at me.

A Backhoe

Here is a picture of a backhoe

The Backhoe that Jim was on didn’t have a cab on it. He was all bundled up trying to keep warm. I believe when he pulled down his face warmer, he too was wearing a beard. He said that before he could go home that day he had to finish this rush job to dig a ditch all around the back and side of the garage.

When I returned the next summer Jim asked me if I remembered him digging the ditch in the snow that day in March. I told him I did. Then he said, “Come here.” We walked around the side of the garage, and sure enough. There was the ditch still open leading around the side and back of the garage. He said, “It was such a rush job I had to stay out in the snow digging this ditch before I could go home, and it has been left untouched since then.

The reason I bring this up, was because the ditch he had been digging was for the conduit that went from the handhole around the back of the garage and over to the warehouse. Later that summer the Construction crew from downtown came out to the plant and laid the conduit in the ditch and covered it back up. So, I knew how the cable needed to run from handhole to handhole over to the warehouse. Oh. Before I forget. Here is a picture of Jim Heflin with a beard:

The Splittin' Image of Jim Heflin

So, back to figuring out how to get the cable to that warehouse. I measured how far it was from the punch down blocks to where it went down into the ground. From there I walked with my normal gait (which I knew was exactly 30 inches – remember?) counting my steps.

I measured how many steps it was to each handhole and over to the warehouse. where the conduit came up out of the ground and went into the warehouse. In this manner I calculated that I needed 775 feet exactly.

I figured I didn’t want to use the 100 pair cable. That was a lot more cable than we would ever need for this job, so I went up to Bill Bennett’s office and told him that I needed 775 feet of 50-pair telephone cable to go from the garage to the warehouse. He said that he would order some.

I don’t remember what time it was when I woke up in a cold sweat in the middle of the night thinking that the length of cable was just going to reach the telephone junction box, and not enough to comfortably reach the punch down blocks halfway up the junction box. So, when I arrived at work in the morning I went straight to Bill’s office and told him that I should have ordered at least 800 feet of cable instead of 775, just to be safe. Bill told me that he had already placed the order for 775 feet. It was too late to change it.

I thought to myself… surely when you order 775 feet of cable they will send some reasonable amount, like 1000 feet. Would they really cut it off at 775 feet exactly. So, I told myself it would be all right.

Sure enough. a couple of days later a reel of 50 pair telephone cable showed up in the electric shop. In big numbers written on the side of the real in red marker were the numbers “775 ft.” Oh geez.

Ok. Somehow I was going to have to make this work. Cross my fingers that maybe my stride was only 28 and a half inches now instead of 30 inches and I had measured it longer than it really was.

So, I pulled the cable from the garage, through the manholes over to the warehouse. In order to pull it from the last handhole into the junction box in the warehouse I had strapped some mule tape to it that I had strung earlier through the conduit using a fish tape. I remember going inside and beginning to pull the last bit of the cable to the junction box hoping to see the end of the cable come up out the conduit.

As I was pulling the cable, I could feel the cable beginning to bind up as it was tightening up in the last handhole. I was still only holding mule tape when I couldn’t pull anymore. Meaning that I didn’t have any cable yet.

So, I went back to the garage and pushed as much cable into the conduit that I could and still punch down the wires on the punchdown block. I even lowered the punchdown block in the junction box hoping that the extra foot would help. Then I went to each handhole and pulled the cable from the garage in the direction of the warehouse until it was as tight around the corners as it would go.

I had managed to pull an extra 2 feet or so into the last handhole. Now all I had left was to go into the warehouse and pull the mule tape to see if the cable would reach the junction box. — Suspense. Yeah. I know.

When I pulled the last 2 feet of cable from the handhole into the junction box, the end of the cable came out. But only about 1 foot of cable was in the junction box. A punchdown block is about 1 foot long.

So, in order to be able to punch the telephone cable down on the punch down block, I had to put the punchdown block at the bottom of the junction box, right where the cable came out of the conduit. On both ends of the cable, I never had to cut one inch of cable from either end. After making sure I had every inch of cable pulled tight through every handhole, I punched down both ends using the handy dandy Telephone wire punchdown tool.

I told myself that from now on, I was always going to throw in a couple hundred extra feet whenever someone asks me how much cable I need. That was too close! You would have thought I learned my lesson.

Now, 22 years later, I still have the same problem as a business analyst at Dell. Part of my job is estimating how long it is going to take to complete various parts of a project. I always make the same mistake and try to over-analyze it so that I can give a really accurate value. The problem is, that I don’t take into account that things take longer than you would think because of factors out of our control.

My project managers know me well enough to take the number that I give them and add a decent amount of time to my estimates. I even tell them that they should because I always underestimate the time. I always estimate how long it would take me to do it personally and I’m not usually the person that is actually writing the code.

Through the last 12 and a half years while working at Dell, I have never missed a go-live date. Oh. Just like this story, we finish on time, but with little or no time to spare. We are always up to the wire. Beginning right when I said we would and ending on the date we planned. Believe me. Just as I pulled every inch of slack out of that cable that day, we end up doing the same with the progress of our projects.

So, I guess I still haven’t learned to properly pad my estimates to reduce the risk of falling short. I think it has something to do with my personality and the way everything has to be mathematically calculated in my head.

      In the early 70s I was an assistant to a surveyor in a large electrical contractors when we tendered for, and won, a contract to rewire a local Town Hall, the unusual thing about the job being that the engineers had specified pyro (fireproof) cable throughout the building, some of which was large three phase stuff and very expensive.

      We scaled up the runs from a 1:100 drawing and placed the orders according to those measurements, each of the large cables being cut specially for that run – every single length was wrong when it was installed, short by several feet.

      It took a lot of measuring on site to realize that the drawings were totally inaccurate, this was a Town Hall that had been built in stone around 150 years earlier and some of the walls were two or three feet thick, on the drawings they looked like standard stud walls.

      Expensive lesson to learn but I kept my job 🙂

Turning the Tables on a Power Plant Telephone Interloper

Originally posted June 13, 2014:

When discussing Telephones at the Coal-Fired Power Plant in North Central Oklahoma, I have to remember that some of my readers have a completely different perspective of telephones than me. My children grew up probably never seeing a real rotary dial phone except in movies or old TV shows. It might be a little hard for them to imagine a telephone being a possible murder weapon. Telephones have come a long way since I grew up in the 1960’s and 70’s.

A Rotary Dial Telephone

A Rotary Dial Telephone

When you turned the dial on a Rotary phone you put your finger in the hole on the number you want to dial and then you swing it around until your finger bumps up against the metal bracket. When you pull your finger out of the hole, the phone sends a rapid succession of pulses to the telephone company telling them what number you just dialed. It was very… well…. tedious and manual…. and not even electronic. It was electric signals and switches. “Mechanical” is the word I think I’m trying to say.

Even the way you received a dial tone was by sending something called a “Ring-to-ground” signal to the telephone company. That would happen when you would lift the receiver off the hook. There are only two wires used to communicate in an old phone and only one of those had voltage on it. when you ground that wire (called the “Ring”) momentarily, the phone company would then send a dial tone to your phone.

You could actually do this on a dead phone line at times when the phone company had shut off your service. On an old pay phone, when the proper coin was inserted in the phone, the coin itself was used to ground the ring wire, thus telling the telephone company to send the dial tone, allowing you to use the phone. In 1983 there was a movie called “Wargames”.

Wargames Starring Matthew Broderick and Ally Sheedy

I had learned about how these telephones worked from Bill Rivers just before going to watch this movie. During the movie Matthew Broderick’s character needed to make a phone call at a pay phone but didn’t have a coin. By taking the mouthpiece off of the transmitter, and using a metal pop top he found on the ground, he was able to ground the “ring” wire to the pay phone, and he received a dial tone. There was a good ol’ boy sitting behind me in the movie theater that said, “You can’t do that!” — Being the newly educated smart (-alec) guy I was, I turned around and said, “Yeah. You really can.”

Anyway. This isn’t a story so much about how old phones work. I just wanted to bring the younger readers back-to-date on phones since now they don’t really call them telephones anymore. It is more like, “Smart Phone” and “Cell Phone”, “Mobile Phone” or just “Phone”. The phone in the house isn’t even referred to as a telephone. We now call them “Home Phone” to distinguish them from the actual phones that we use.

Anyway, when I joined the electric shop in 1983, I learned about the phone system. We didn’t use the older Rotary Dial phones at the plant. We were one step up. We had “Touch Tone” Phones.

A Power Plant Touch Tone Phone

As I have mentioned in previous posts, we had our own telephone computer at the Power Plant. It was called a ROLM phone system. See the post “A Slap In the Face at a Gas-fired Power Plant“.

A ROLM Phone Computer

A ROLM Phone Computer – I like showing this picture of the Phone computer

To give you an idea of the technology used by this phone system, you connected to it using a “teletype” terminal that you connected to a telephone by clipping the receiver in a cradle. Then you dialed the phone computer. When you connected, it was at 300 Baud. Think of 300 bytes per second, only using audio…. like a fax machine. — It was like connecting using a modem. 300 baud meant that when it typed out the results on the paper that scrolled out the top, you could watch it as it slowly printed out each line. The maximum speed of the terminal was 300 baud.

 

This is the TI Silent 700 Terminal. We used this exact model of Teletype terminal at the Power Plant

In this picture you can see the cradle in the back where the phone receiver would fit in those two rubber cups.

After many years of going to the lab to connect to the telephone computer to make changes and to monitor the telephone traffic, in 1992 I decided to bring my 8088 computer to work and set it on the desk in the electric shop. We didn’t have our own computer yet. At that time the only people that had computers were office workers and the Shift Supervisor. We had started a computer club and having a computer in the shop was a big help. I had just replaced this computer at home with a 486.

This is a Leading Edge computer. My father had this one. An earlier version than the 8088 that I was using.

I had a modem on my computer, so I tried connecting to the telephone computer, and it worked! So, sometimes during lunch when Charles Foster and I were sitting there talking about movies we had seen while eating vegetables from his garden, I would connect to the ROLM computer and just watch the call log. I could see whenever someone was dialing in and out of the plant.

We had a special call in number into the plant that allowed you to make “trunk” calls. This is another term you don’t hear much anymore. You see….. for the younger readers (again)…. long distant calls used to cost a lot of money. You would be charged by how many minutes you were on the call. During the day, it could be as high as $3.00 a minute to call across the country. Amazing huh? Because today, most of you with cell phones and even your land lines (which are rarely real land lines anymore) long distant phone calls are now free with your phone plan.

Yeah, if you wanted to call someone in the next town over, you would have to pay a fee for every minute you were on the call…. That was when AT&T had a monopoly on the phone lines in the United States. Sure, you only payed $7.00 each month for your phone, but you could only call people in your immediate area or you would be charged extra.

A Trunk line gave you access to a much wider area. The Electric company had a trunk line that gave them access to most of Oklahoma. You could dial into a local number that would connect you to the company phone system. Then after entering the correct password number, you could dial access numbers that would take you to another office location in the electric company. Once on that phone system, you could dial to get an outside line, and then dial a local number in that area.

Our plant had three access numbers that allowed you to dial out locally to Stillwater, Ponca City and Pawnee. This was useful when a foreman needed to call people out to work. They could dial into the plant, then back out to one of these other towns and then dial the local phone number of the crew member they were trying to reach without incurring a personal charge on their phone line.

So, here I was in 1992 during lunch watching the phone traffic in and out of the plant (not exactly NSA style, but sort of), when I saw something unexpected. A long string of numbers showed up. Someone had dialed in on the Stillwater trunk, then dialed out to the Corporate Headquarters trunk, then out to Oklahoma City and from there they placed a long distance call to a phone number in the same area code. The prefix on the phone number was familiar to me. It was a Ponca City phone number. I had lived in Ponca City for three years when I had been married, from 1986 to 1989. I knew a Ponca City phone number when I saw one.

I thought this was odd, because it wouldn’t be normal for someone to dial from Stillwater through out plant to Oklahoma City only to call a Ponca City phone number when they could have dialed the local Ponca City access code. Then they wouldn’t have had to make a long distance call which bypassed our trunk call system causing the electric company to be billed for the long distance telephone call.

At the time I was a CompuServe user. This was when the World Wide Web was in it’s infancy. I was still using a DOS computer. When I connected to the Internet, it was either by using my dad’s Internet account from Oklahoma State University where I would use Telnet to access a bunch of mainframe computers all over the country, or I would use the DOS-based version of CompuServe. CompuServe was the king of Internet access before America Online came around and seemingly overnight made CompuServe obsolete.

A screenshot of the CompuServe Program I was using.

A screenshot of the CompuServe Program I was using.

In 1992, CompuServe had a service where you could look up phone numbers and find out whose number it was. Imagine that! Yeah. That was one of the neatest features on CompuServe! That and getting stock quotes. — Like I said…. There was no “www.whitepages.com” online. The only catch to using the reverse phone number feature, was that it was like making a long distance call. It cost money. You were charged by the minute for using the CompuServe reverse telephone number service, with the least amount being a dollar.

So, I bit the bullet and accessed the Phone Number lookup section of CompuServe. I quickly typed in the number. When the name and address of the user popped up, I quickly hit “Print Screen”, and then exited the service. My fee came to $1.00, but at least I knew what number had been dialed in Ponca City.

Charles, Scott Hubbard and I were a little excited by the time Terry Blevins walked into the electric shop office after lunch was over, I told him what I had seen.

When I told Terry the name of the person that had received the long distance call, he recognized the name right away. When I gave him the address, he was sure he knew who it was. The phone number belonged to the Music Director at the Ponca City High School. His son was attending college in Stillwater, Oklahoma.

Well, that sort of cinched it. We had a pretty good idea who had made the call. It was a college student calling home, who had been given the phone number most likely by a fellow student who knew the code to call home in Oklahoma City. So, the only local access code this guy knew was how to dial through our plant to Oklahoma City and back out where he was free (but it was not free for us) to make a long distance call home.

Armed with this knowledge, I headed up to the front office. I went straight to the Plant Manager, Ron Kilman’s office. I told Ron what I had found. I explained in detail how the person had dialed from Stillwater into our plant and then to Oklahoma City and out and then placed a long distance call to Ponca City leaving us with the phone bill. Since it was the middle of the day, the cost of a long distance call was not cheap.

I told Ron that I had used CompuServe to lookup the phone number and that Terry had said that it belonged to the Music Director at the Ponca City High School and that he had a son in college in Stillwater. I was all ready to pounce on this guy. This was a fraudulent use of the telephone service and there were some pretty strict laws then about stealing long distance from someone else.

Ron, being the more level-headed of the two of us thought about it for a minute and said, “What would be the best way to stop this from happening?” — Oh. Well.  I was so intent on catching the culprit, I hadn’t thought about that angle…. “Well….” I said, “We could change the pass code used to log into our phone system. We would just have to tell our supervisors what the new number is.”

Ron asked me what it would take to do that. I told him I could do it in two minutes. We quickly settled on a new 4 digit pass code and I left his office and returned to the electric shop and made the change essentially turning the tables on the Telephone Interloper. I suppose the college student in Stillwater was lucky that our plant manager at the time was the type to forgive and forget.

Three years later the entire electric company phone system was replaced by a new AT&T computer which was managed by AT&T. As you can tell… Technology just keeps moving forward making seemingly really neat new inventions quickly obsolete.

      I still stand in awe at all the talent we had at the plant- never has one place had so many guys of remarkable skill and overall just good people and kind hearted.

    Your memory still amazes me. I don’t remember that at all.
    I’ll bet most young people today don’t know why we say to “dial” a phone number!

      It was just a moment in your busy day. It was the highlight of my week.

Learnin’ ’bout ‘lectricity with Andy Tubbs

Originally posted January 18, 2013:

The day I became an electrician at the coal-fired power plant, I suddenly became an expert in electricity. I think it was on Tuesday, just one day after joining the electric shop that I was walking through the welding shop when someone stopped me and asked me how they would wire their living room with different light switches at different corners and make it work correctly. As if I had been an electrician for years. Luckily I was just finishing a house wiring course at the Indian Meridian Vo-Tech in Stillwater, Oklahoma and they had us figure out problems just like those.

Within the first week, George Alley brought a ceiling fan to the shop that he had picked up somewhere and was wondering if we could get it to work. My foreman Charles Foster thought it would be a good small project for me to work on to help me learn about electrical circuits.

After all, this ceiling fan could go slow, medium and fast, and it could go forward or reverse. Only at the moment, all it would do was sit there and hum when you hooked up the power. — So that was my first “unofficial” project, since the main goal was to make George happy so that he would help us out when we needed something special from the mechanics.

When I was a janitor, I had observed the electricians preparing to go to work in the morning, and often, one of them would go to the print cabinets at one end of the shop and pull out a blueprint and lay it across the work table and study it for a while. Then they would either put it back or fold it and put it in their tool bucket and head out the door to go do a job. Now, it was my turn.

Andy Tubbs was one of the two people that played the best jokes on me when I was a janitor. Larry Burns was the other person, and he was the person I was replacing as he had moved to another plant. Andy was the one that had taken the handle off of my push broom the moment I had my back turned so that when I turned around to grab my broom, only the broom head was on the floor, while the broom handle was across the counter by the lab, and Andy was across the other side of the room trying to act like he wasn’t paying attention, but with an expression like he had just played a darn good joke. — I actually had to go back into the bathroom I was cleaning so that I could laugh out loud. I was really impressed by Andy’s ability to play a good joke.

While I’m on the subject, shortly after I became an electrician, I was sitting in the electric shop office talking to Charles when he stopped and said, “Wait…. Listen….” We paused, waiting for something…. A few seconds later, the sound of a hoot owl came over the PA system (what we called the “Gray Phone”). Charles said, It’s an interesting coincidence that the only time the perfect sound of a hoot owl comes over the Gray Phone is when Andy Tubbs is riding in an elevator by himself or with a close friend.

I had been sent with Andy Tubbs and Diana Lucas (later Diana Brien), to go to the coal yard and figure out why some circuit for the train gate was not working. Andy had pulled out the blueprints and was studying them. I came up alongside him and looked at all the blue lines running here and there with circles with letters and numbers, and what I recognized as open and closed switches….

Here is a simple electric circuit drawn in the style of many of the electric blueprint drawings

Andy stopped and gave me a momentary lecture on the nature of electricity. It was so perfectly summed up, that for years whenever I thought about the nature of electricity, I always began with remembering what Andy told me. He said this:

“Think of electricity like water in a hose. Voltage is the water pressure. Amperage is the amount of water going through the hose. You can have the nozzle on the end of the hose shut off so that no water is coming out and then you have no amperage, but you will still have the pressure as long as it is turned on at the source so you will still have voltage.”

“In these diagrams, you just have to figure out how the water is going to get from one side to the other. These circles are things like relays or lights or motors. When the electricity makes it through them, they turn on as long as the electricity can make it all the way to the other side.”

That was it! That was my lesson in ‘lectricity. All I needed to know. The blueprints were big puzzles. I loved working puzzles. You just had to figure out how you were going to get something to run, and that meant that certain relays had to pickup to close switches that might pick up other relays to close other switches. I found that most of the electricians in the shop were good at working all sorts of puzzles.

Andy went to the cabinet and grabbed one of the Simpson multimeters and a handset for a telephone that had red and black wires wrapped around it.

A telephone handset that looked like this, only it had a battery taped to it, and two leads coming out the bottom

A telephone handset that looked like this, only it had a battery taped to it, and two leads coming out the bottom

I was puzzled by this at first. I thought I would just wait to see what we did with it instead of ask what it was for. We grabbed our tool buckets (which also doubled as a stool and tripled as a trash can as needed), and put them in the substation truck. The other truck was being manned by the designated electrician truck driver for that week. We needed a truck that we could drive around in without having to hold up the truck driver.

We drove to the coalyard and went into the dumper switchgear. Andy and Diane opened up a large junction box that was full of terminal blocks with wires going every which way in an orderly fashion. They located a couple of wires, and Andy unwrapped the wires from the handset while Diane removed the screws holding the wires to the terminal block. Then Andy clipped one wire from the telephone handset to each of the two wires and handed me the phone.

Diane told me that they were going to drive down toward the train gate where the railroad tracks come into the plant and try to find these wires on the other end. So, what they needed me to do was to talk on the phone so when they find my voice, they will know that they have the right wires. Diane said, “Just say anything.” Then they left the switchgear and I could hear them drive away in the truck.

Well. This was my opportunity to just talk to no one for a while without interruption. How many times do you get to do that in one day? Probably only when you are on the way to work and back again if you aren’t carpooling with anyone. Or you’re sittin’ on your “thinkin’ chair” in a single occupant restroom. So, I just kicked into Ramblin’ Ann mode and let myself go. I believe my monologue went something like this:

“The other day I was walking through a field, and who should I run across, but my old friend Fred. I said, ‘Well, Hi Fred, how is it going?’ and Fred told me that he was doing just fine, but that he had lost his cow and was wondering if I could help him look for it. I told him I couldn’t right now because I was helping some people find a wire at the moment, and if I became distracted, we might not only lose the cow, but we might lose the wires as well, so I better just keep on talking so that my friends on the other end can find the wires they are looking for. After that I went to the store and I picked up three cans of peas. I thought about getting four cans of peas but settled on three and brought them to the checkout counter, and while I was waiting in line I noticed that the little boy in front of me with his mom was looking at me as if he wanted to have one of my cans of peas, so I quickly made it clear to him that I was buying these cans of peas for myself by sliding them further away from him and glaring at him. Luckily the boy wasn’t persistent otherwise I would have broken down and given him a can of peas because he was looking kind of hungry and I was feeling sorry for him, though, I didn’t want him to know how I was feeling, so I put on a grim expression….”

Needless to say… My monologue went on for another 15 minutes. Yes… .15 minutes. I had expected Andy and Diane to have returned earlier, but I didn’t know how hard it was going to be to find the other end of the wires, so I just kept on ramblin’ to the best of my ability. It’s like what it says in the Bible. If we wrote down everything I said, it would have filled many volumes. Being a Disciple of Ramblin’ Ann came in handy that day. For more about Ramblin’ Ann, you can read the following post:

Ed Shiever Trapped in a Confined Space With A Disciple of Ramblin’ Ann

When Andy and Diane returned they said that they had found the wires right away, but that they had sat there for a while just listening to me ramble. They said I was cracking them up. They also mentioned that they thought I was completely crazy. Well. I was glad that they found the wires and that my rambling abilities had come in handy.

Five months after I had joined the electric shop, Andy and I were sent to Oklahoma City to learn about a new kind of electric troubleshooting. It was called “Digital Electronics”. I had just finished my electronics class at the Vo-Tech, and so I was eager to put it into practice. Andy and I went to a two day seminar where we learned to troubleshoot what was basically a PC motherboard of 1984. We used a special tool called a digital probe and learned how the processor worked with the memory chips and the bios. It wasn’t like a motherboard is today. It was simple.

A simple Motherboard like this

A simple Motherboard like this

It was just designed for the class so that we could use the digital probe to follow the different leads from the chips as the electric pulses turned on and off.

We were using digital probes similar to this

At the time I was thinking that this was a waste of time. I had been learning all about troubleshooting electronic circuits from Bill Rivers and Sonny Kendrick. I couldn’t see how this was going to be useful. I didn’t know that within a couple of years, most of our electronic circuits in the precipitator controls were all going to be replaced with digital controls, and this was exactly what I was going to need to know.

So, Andy and I spent two days learning all the basics of how new computers were going to be working. This was the same year that Michael Dell was beginning his new computer company further down I-35 in Austin Texas. Who would have thought that 18 years later I would be working for Dell. But that’s another lifetime away…

Early in my career at the Seminole Plant I learned when someone paged you on the gray phone, you should always check the earpiece of the phone before you put it on your ear – it might be full of clear silicone calk (or worse). Also, at the end of the day when you reach to pick up your lunch box, you should pick it up gently. Someone could have slipped a full bottle of mercury (like 20 pounds) in it. This prevents you from pulling the handle off your lunch box or hearing it crash to the floor, smashing everything in its path. It’s amazing what Power Plant Men are capable of doing.

    We used hand lotion in the electric shop for the gray phone trick. I remember Andy catching an unsuspecting operator in the main switchgear more than once.

Working Smarter with Power Plant Dumb Terminals

Originally posted January 3, 2014:

After the reorganization at the coal-fired power plant in North Central Oklahoma during 1987, a bunch of new faces showed up at the plant.  I mentioned in last week’s post that we had a new plant manager, Ron Kilman (See Post:  “From Pioneers to Power Plant Managers“).  In that post I also mentioned that the PC age was rapidly growing and I had bought a computer of my own and was eager to learn more.  The Electrical Supervisor, Leroy Godfrey had retired, and was replaced by a guy named Tom Gibson.  Tom was a good supervisor who was willing to think out of the box.

Tom gave me one of my first assignments directly by calling me to his office.  Well, Leroy had never really called me to his office before.  When Leroy wanted to chew you out, he was happy to come down to the Electric Shop and do it, so I didn’t really know what to expect by being “called to his office”.  Believe me… it wasn’t the last time he had “called me to his office.”  But it was the most satisfying time.  Mainly because this time, when I arrived, Tom’s face wasn’t beet red with anger like it was on one later occasion.

This is what Tom told me to do…  He said that we needed to install computer terminals all over the plant.  They had a chart where they wanted the terminals to go.  There were about 15 locations all over the plant including the coalyard which was about 1/2 mile from the main plant.  Along with those, there were a bunch of IBM Network printers that needed to be installed with the terminals.

Then Tom told me the best part.  He wanted me to do it all myself.  Then he told me an even better part…. He said, (and I quote) “I want you to learn everything you can about this computer stuff.  I think it will come in handy.”  As my friend Stephen Todd at Dell would say, “That was the ‘Keys to the Kingdom”.  I told him I would be glad to do everything he asked.

That last part later came back to haunt Tom…. but he did tell me…. learn “everything” I could about the computer.  When he was referring to “The Computer”, he was talking about the company mainframe, a Honeywell system that resided in Oklahoma City at Corporate Headquarters.

The Terminals I was going to install were called “Dumb terminals”.  they weren’t computers, they were just monitors with a keyboard that connected directly to a switch back in the telephone room that was connected via a microwave link directly to Oklahoma City and the Honeywell system:

A DEC terminal like this.

A DEC terminal like this.

So, when I returned to the electric shop, I began my “hacker” apprenticeship.  One that would later allow me to harass Gene Day in the Control Room, confuse Dick Dale in the warehouse, cause headaches for the IT department downtown, and finally cause the President of the Electric Company to personally call our Plant Manager Ron asking who was this guy Kevin Breazile!  Hence the reason for Tom Gibson’s beet red face a few years later.  But that is another story for another time.

I had two things right away that I had to figure out.  How was I going to run cables from the telephone room in the office to each of the places around the plant that needed a computer terminal and what are these funny connectors and what do I need to do with them?

A Modular DB25M to RJ45 Adapter

Ok, so I figured they plugged in the back of the terminal and then there was a Cat1 cable (no, not a Cat3, a Cat1) that plugged into that, and needed to plug into a jack in the wall that I was going to have to install.  They called these funny connectors “Hoods”.  The 25 pin Hoods that we used were blue.  We had 9 pin hoods also that we used for the actual PCs that the clerks and the chemist were using.  They had an emulator program to make them act like a dumb terminal:

In an early post called “Power Plant Men’s Club Prizes and a Story of Luck” I explained how I have always been cursed with being very lucky.  Well, that’s what some may call it, but I prefer to believe that one of my best friends St. Anthony helps me out at certain times.  Well, this was one time when I asked for his assistance.  St. Anthony of Padua is considered the Patron Saint of lost items.  So, I asked him to help me figure out how I was going to do all this work in a reasonable amount of time.

As is often the case, St. Anthony pointed me in the right direction.  This particular day, he told me to tell my problem to Charles Foster.  My close friend and one of the two Electric Shop foremen (not mine.  I was working for Andy Tubbs).  So, during lunch I told him what Tom Gibson told me to do, and showed him the blueprints where they wanted the terminals placed throughout the plant.

One of the places that needed a terminal was right there in the electric shop office.  Charles looked around the office and said, “You know what?  there used to be an old intercom system in this office that I think goes up to the telephone room.  In fact, I think all the intercoms that were originally installed in the plant went to the telephone room.”

An old intercom sort of like this only in a box that sat on the desk and it had more switches

An old intercom sort of like this only older and in a box that sat on the desk and it had more switches

I vaguely remembered the intercoms when I was working as a summer help as there used to be an old box sitting in the garage when I worked for Stanley Elmore.  They were later cut out and removed, because it wasn’t really practical and so it wasn’t used.  Charles told me to start there, because there were intercoms everywhere.  In the control room, the warehouse, and even in the coalyard!  And definitely in the office area.  This was just what I needed to hear.  My work was already half done.

I pulled the cables out from under the desk where they had been cut and checked them out.  There were definitely enough cable pairs to do the job.  In most places I had to install both a terminal and a printer, so I had a lot of dual wall jacks just for this job:

A dual RJ45 Wall Jack

A dual RJ45 Wall Jack

There were some places where the intercom system didn’t go where I needed to install either a dumb terminal or at least connect a computer.  So, I was looking for any kind of alternate way to install the jack without having to run cables all the way from the telephone room to these locations.  So, I went out and bought a book about networking so that I could learn more about what was really going on.  If I had bought it a few years later it might have been called “Dumb Terminals for Dummies”, but the Dummies books hadn’t come around yet.

I have since thrown that book away after using it for years to prop up the corner of our sofa bed for the times when my mom would come and visit and she would sleep on the bed, only it had a broken bracket, and the Networking book was just the right thickness to level the bed…. But there was one page in the book that I found that allowed me to hook up dumb terminals in places where there was only a phone line.

You see.  When the phone lines were run throughout the plant, they used a three pair cable.  Well.  A phone really only uses two wires (or one pair).  so, this left 4 more wires not doing anything.  The only problem was that the dumb terminal used 4 pair, or 8 wires…

An RJ45 Cable

An RJ45 Cable has 8 wires

So, when I was reading the networking book, I ran across a diagram that made me stop and stare.  I like to think that I was holding a half eaten apple in my hand and I had just taken a bite when I stopped mid-bite and stared.  It would have been a nice picture to remember sort of like when the apple fell on Newton’s head.  Only we didn’t have cellphones with cameras in those days, so no one was around to take my picture.  The diagram I saw was this:

The pin configuration for an RJ45 connector

The pin configuration for an RJ45 connector

What?  This showed 4 of the wires are nothing but grounds….  The network cable only really uses 4 of the 8 wires.  Which means I only needed two pair.  And guess what?  The phone lines run all over the plant were 3 pair with only one pair being used!  So, I was able to install the computer jacks right next to the telephone jacks and use the same cable that the telephone was using, and they all tied back to the telephone room where the main computer switch was located that connected to the Mainframe computer back in Oklahoma City through something called a Memotec X.25 Modem.

So, now that I have gone through all this detail to tell you how I was able to quickly install all these terminals and printers around the plant in a way as if it is exciting (because it is to me).  I know that many of you are so bored out of your gourd that you have already stopped reading before you have reached this sentence….  I suppose those of you that are still following along are wondering “Why?”

Why would we want to install all these dumb terminals throughout a power plant that connected to the Honeywell Mainframe down at Corporate Headquarters?  Well.  It was because all the plant operators, mechanics, welders, machinists, electricians, instrument and controls and heavy equipment operators were going to start using it to do stuff.  Yeah.  All of us were being introduced to the computer age.  From the janitor on up.

Each printer had 4 character ID that identified it, so if you were looking at a work order on the terminal, you could choose to print it.  You just had to know the 4 character number and you could print the work order out on any computer in the company.  Usually, this meant, you wanted to use the printer that was closest to you.  But if you wanted to print something out for the warehouse, as long as you knew their printer ID, you could send them a printout of some part that you wanted them to retrieve for you.  Then call them up and tell them you printed something out on their printer.

Ok.  So the average Joe didn’t see much benefit, but it did get them used to seeing computer monitors all over the place, which at least helped them in the future when the real computers showed up.  Right now, they were just “Dumb Terminals” and that’s what a lot of the operators and maintenance people thought… they are just dumb…

I, on the other hand was in hog heaven.  You see.  I had called downtown to the IT department and asked to get a user name so that I could log directly into the mainframe.   After all, my supervisor Tom had told me to learn “everything” I could about “this computer”.  So, I took him up on it.  I quickly was learning UNIX commands, though at the time, I didn’t know that’s what they were called.

I began learning the Computer language called “A” before I realized there was a “B” language and a “C” language, and that C was the one that was really used at the time.  As it turned out the mainframe had manuals for everything right on it.  That is how I was able to cause so much trouble the next few years.

Oh, and one more interesting thing I discovered on the mainframe.  It had this interesting feature called “Email”.  Yeah.  Only, after figuring out how to pull up a list of all the emails on the system I found that there was only a handful of people that actually had e-mail addresses.  So, the only person I would email on the mainframe was an engineer named Craig Henry.

Craig Henry.  Engineer and Gentleman

Craig Henry. Engineer and Gentleman

I had met him briefly once, but in the next few years, he was a valuable source of information.  Email seemed like a great idea, but what good was it if there was only a few people you could send an email?

As for Craig Henry… As Humphrey Bogart said to Claude Rains in Casablanca, “This is the beginning of a Beautiful Friendship.” Come to think of it… Craig Henry sort of reminds me of Claude Rains…  I must admit, I learned a lot more from him than he ever learned from me.

When Enough Power Plant Stuff Just Ain’t Enough

Originally posted March 21, 2014:

As a young novice Power Plant Summer Help, I had watched seasoned Power Plant Men measure the distance between two points by walking between them and multiplying the number of steps by three. At first I wondered how they could be sure that their strides were all exactly three feet apart. Because the end result of these actions usually came out pretty close to their estimate, over time I began to think that the length of the stride of any respectable Power Plant Man must naturally be three feet.

So, one day when I was working on going to pull a cable from one manhole to the next, I decided I wanted to know the distance before I pulled a lot of cable off of the cable reel. So, I remember that I grabbed the tape measure out of my tool bucket and began walking at as normal of a gait as I could.

I thought if I measured the first step, or even the last step I took that it would somehow be a different size because I wasn’t moving at my normal speed. So. I figured I would surprise myself by just stopping at some random step as I walked between the two manholes.

I don’t know if anyone was watching me as I stood out in the field just north of the two smokestacks, if they were watching me, then they would have seen me pause and stand still for a moment looking down. Start messing around with my feet. Then take a few more steps. Pause once more and do the same thing.

What I was doing was stopping in the middle of my stride when I had just put a foot down, before I lifted the other foot and with my Stanley metal tape measure, I was measuring the distance from the back of one heel to the back of the other heel.

I can’t say that I was too disappointed to find that my stride was not exactly three feet. I hadn’t figured I was completely Power Plant Man material anyway. It turned out to be exactly 30 inches. Or two and a half feet. So, I realized I was about 3/4 Power Plant Man measured by my stride.

I found that I could easily walk between two points and measure the distance with great accuracy by multiplying the number of steps by two and a half feet. With great knowledge comes great responsibility…. or…um… something like that. Hence the story about how enough was not quite enough.

During the spring of 1992 I was tasked with running telephone cable to various points around the plant. We were going to begin installing a new computer network known as the “Ethernet”. When I first heard the name, I thought they were referring to something in space, where it used to be the belief that there was an area called the “Ether”. But as it turned out, it was the regular network that is still in use today.

Dennis Dunkelgod from Oklahoma City had come to the plant with a bunch of drawing much like they did a few years earlier when they wanted me to install the Dumb Terminals all over the place. (See Post “Working Smarter with Power Plant Dumb Terminals“). This time the diagrams included places where PCs were going to be placed. And where the network server was going to be setup. This required much better quality wiring than the dumb terminals.

So, Dennis saw to it that I had 1/2 mile of 100 pair telephone cable to run from the main plant up to the coalyard. Along with the cable came a box of 25-pair punchdown blocks. I’m sure you’ve seen punchdown blocks in movies when someone is tapping into a phone line, so they go up to these punchdown blocks and hook their handset up to the wires and listen in.

One of the places where I needed to place a number of computers was in the warehouse and the warehouse office. There were no good phone lines running to this building. There were barely enough to take care of the phones that were in the office at the time. So, I needed to figure out how to run the telephone cable to the warehouse which was the southern-most building in the main plant grounds.

Across the drive from the warehouse was the garage. When I looked at the phone panel in the garage, this looked like a good place to tap into the phone system. There were two 25 pair blocks in this building for only one phone. Enough for all the computers in the garage and the warehouse.

All I needed to do now was figure out how to pull a 50 pair telephone cable from the garage over to the warehouse. After looking for the conduit that brought the existing cable into the garage, I was able to determine how it went over to a hand hole at the north corner of the building and then over to a manhole not far away.

A hand hole was a shallow hole in the ground that has buried conduit coming into it. Our handholes had a large piece of concrete covering it.

When I looked at the handhole I suddenly remembered that in during the week of March 21, 1981 I had visited the Power Plant to pick up my application to apply for working as a summer help for my 3rd summer. I was wearing a beard that day when I arrived. While I was in college, I usually wore a beard in the winter to keep my face warm because I rode my bike a lot, and it helped keep my face warm.

I had my friend Tim Flowers with me that day because he was going to apply to be a pre-novice Power Plant Man and work as a summer help also that summer. It was snowing that day and it was almost 4:30pm. Quittin’ Time by the time I had said hello to the many Power Plant Men that I hadn’t seen since the previous summer.

We were heading back out to the parking lot when I heard someone hollering at me. I looked over toward the garage and there was Jim Heflin sitting on a backhoe digging a ditch. He had turned off the backhoe so that I could hear him yelling at me.

A Backhoe

Here is a picture of a backhoe

The Backhoe that Jim was on didn’t have a cab on it. He was all bundled up tying to keep warm. I believe when he pulled down his face warmer, he too was wearing a beard. He said that before he could go home that day he had to finish this rush job to dig a ditch all around the back and side of the garage.

When I returned the next summer Jim asked me if I remembered him digging the ditch in the snow that day in March. I told him I did. Then he said, “Come here.” We walked around the side of the garage, and sure enough. There was the ditch still open leading around the side and back of the garage. He said, “It was such a rush job I had to stay out in the snow digging this ditch before I could go home, and it has been left untouched since then.

The reason I bring this up, was because the ditch he had been digging was for the conduit that went from the handhole around the back of the garage and over to the warehouse. Later that summer the Construction crew from downtown came out to the plant and laid the conduit in the ditch and covered it back up. So, I knew how the cable needed to run from handhole to handhole over to the warehouse. Oh. Before I forget. Here is a picture of Jim Heflin with a beard:

The Splittin' Image of Jim Heflin

The Splittin’ Image of Jim Heflin

So, back to figuring out how to get the cable to that warehouse. I measured how far it was from the punch down blocks to where it went down into the ground. From there I walked with my normal gait (which I knew was exactly 30 inches – remember?) counting my steps.

I measured how many steps it was to each handhole and over to the warehouse. where the conduit came up out of the ground and went into the warehouse. In this manner I calculated that I needed 775 feet exactly.

I figured I didn’t want to use the 100 pair cable. That was a lot more cable than we would ever need for this job, so I went up to Bill Bennett’s office and told him that I needed 775 feet of 50-pair telephone cable to go from the garage to the warehouse. He said that he would order some.

I don’t remember what time it was when I woke up in a cold sweat in the middle of the night thinking that the length of cable was just going to reach the telephone junction box, and not enough to comfortably reach the punch down blocks halfway up the junction box. So, when I arrived at work in the morning I went straight to Bill’s office and told him that I should have ordered at least 800 feet of cable instead of 775, just to be safe. Bill told me that he had already placed the order for 775 feet. It was too late to change it.

I thought to myself… surely when you order 775 feet of cable they will send some reasonable amount, like 1000 feet. Would they really cut it off at 775 feet exactly. So, I told myself it would be all right.

Sure enough. a couple of days later a reel of 50 pair telephone cable showed up in the electric shop. In big numbers written on the side of the real in red marker were the numbers “775 ft.” Oh geez.

Ok. Somehow I was going to have to make this work. Cross my fingers that maybe my stride was only 28 and a half inches now instead of 30 inches and I had measured it longer than it really was.

So, I pulled the cable from the garage, through the manholes over to the warehouse. In order to pull it from the last handhole into the junction box in the warehouse I had strapped some mule tape to it that I had strung earlier through the conduit using a fish tape. I remember going inside and beginning to pull the last bit of the cable to the junction box hoping to see the end of the cable come up out the conduit.

As I was pulling the cable, I could feel the cable beginning to bind up as it was tightening up in the last handhole. I was still only holding mule tape when I couldn’t pull anymore. Meaning that I didn’t have any cable yet.

So, I went back to the garage and pushed as much cable into the conduit that I could and still punch down the wires on the punchdown block. I even lowered the punchdown block in the junction box hoping that the extra foot would help. Then I went to each handhole and pulled the cable from the garage in the direction of the warehouse until it was as tight around the corners as it would go.

I had managed to pull an extra 2 feet or so into the last handhole. Now all I had left was to go into the warehouse and pull the mule tape to see if the cable would reach the junction box. — Suspense. Yeah. I know.

When I pulled the last 2 feet of cable from the handhole into the junction box, the end of the cable came out. But only about 1 foot of cable was in the junction box. A punchdown block is about 1 foot long.

So, in order to be able to punch the telephone cable down on the punch down block, I had to put the punchdown block at the bottom of the junction box, right where the cable came out of the conduit. On both ends of the cable, I never had to cut one inch of cable from either end. After making sure I had every inch of cable pulled tight through every handhole, I punched down both ends using the handy dandy Telephone wire punchdown tool.

I told myself that from now on, I was always going to throw in a couple hundred extra feet whenever someone asks me how much cable I need. That was too close! You would have thought I learned my lesson.

Now, 22 years later, I still have the same problem as a business analyst at Dell. Part of my job is estimating how long it is going to take to complete various parts of a project. I always make the same mistake and try to over-analyze it so that I can give a really accurate value. The problem is, that I don’t take into account that things take longer than you would think because of factors out of our control.

My project managers know me well enough to take the number that I give them and add a decent amount of time to my estimates. I even tell them that they should because I always underestimate the time. I always estimate how long it would take me to do it personally and I’m not usually the person that is actually writing the code.

Through the last 12 and a half years while working at Dell, I have never missed a go-live date. Oh. Just like this story, we finish on time, but with little or no time to spare. We are always up to the wire. Beginning right when I said we would and ending on the date we planned. Believe me. Just as I pulled every inch of slack out of that cable that day, we end up doing the same with the progress of our projects.

So, I guess I still haven’t learned to properly pad my estimates to reduce the risk of falling short. I think it has something to do with my personality and the way everything has to be mathematically calculated in my head.

      Hah! my stride (heel to toe) is 3 feet, two strides to the link. That’s what practice does.

      But I have learned to add 10% to everything (nearly), somehow it always gets used. 🙂

      In the early 70s I was an assistant to a surveyor in a large electrical contractors when we tendered for, and won, a contract to rewire a local Town Hall, the unusual thing about the job being that the engineers had specified pyro (fireproof) cable throughout the building, some of which was large three phase stuff and very expensive.

      We scaled up the runs from a 1:100 drawing and placed the orders according to those measurements, each of the large cables being cut specially for that run – every single length was wrong when it was installed, short by several feet.

      It took a lot of measuring on site to realise that the drawings were totally inaccurate, this was a Town Hall that had been built in stone around 150 years earlier and some of the walls were two or three feet thick, on the drawings they looked like standard stud walls.

      Expensive lesson to learn but I kept my job 🙂

Turning the Tables on a Power Plant Telephone Interloper

Originally posted June 13, 2014:

When discussing Telephones at the Coal-Fired Power Plant in North Central Oklahoma, I have to remember that some of my readers have a completely different perspective of telephones than me. My children grew up probably never seeing a real rotary dial phone except in movies or old TV shows. It might be a little hard for them to imagine a telephone being a possible murder weapon. Telephones have come a long way since I grew up in the 1960’s and 70’s.

A Rotary Dial Telephone

A Rotary Dial Telephone

When you turned the dial on a Rotary phone you put your finger in the hole on the number you want to dial and then you swing it around until your finger bumps up against the metal bracket. When you pull your finger out of the hole, the phone sends a rapid succession of pulses to the telephone company telling them what number you just dialed. It was very… well…. tedious and manual…. and not even electronic. It was electric signals and switches. “Mechanical” is the word I think I’m trying to say.

Even the way you received a dial tone was by sending something called a “Ring-to-ground” signal to the telephone company. That would happen when you would lift the receiver off the hook. There are only two wires used to communicate in an old phone and only one of those had voltage on it. when you ground that wire (called the “Ring”) momentarily, the phone company would then send a dial tone to your phone.

You could actually do this on a dead phone line at times when the phone company had shut off your service. On an old pay phone, when the proper coin was inserted in the phone, the coin itself was used to ground the ring wire, thus telling the telephone company to send the dial tone, allowing you to use the phone. In 1983 there was a movie called “Wargames”.

Wargames Starring Matthew Broderick and Ally Sheedy

I had learned about how these telephones worked from Bill Rivers just before going to watch this movie. During the movie Matthew Broderick’s character needed to make a phone call at a pay phone but didn’t have a coin. By taking the mouthpiece off of the transmitter, and using a metal pop top he found on the ground, he was able to ground the “ring” wire to the pay phone, and he received a dial tone. There was a good ol’ boy sitting behind me in the movie theater that said, “You can’t do that!” — Being the newly educated smart (-alec) guy I was, I turned around and said, “Yeah. You really can.”

Anyway. This isn’t a story so much about how old phones work. I just wanted to bring the younger readers back-to-date on phones since now they don’t really call them telephones anymore. It is more like, “Smart Phone” and “Cell Phone”, “Mobile Phone” or just “Phone”. The phone in the house isn’t even referred to as a telephone. We now call them “Home Phone” to distinguish them from the actual phones that we use.

Anyway, when I joined the electric shop in 1983, I learned about the phone system. We didn’t use the older Rotary Dial phones at the plant. We were one step up. We had “Touch Tone” Phones.

A Power Plant Touch Tone Phone

As I have mentioned in previous posts, we had our own telephone computer at the Power Plant. It was called a ROLM phone system. See the post “A Slap In the Face at a Gas-fired Power Plant“.

A ROLM Phone Computer

A ROLM Phone Computer – I like showing this picture of the Phone computer

To give you an idea of the technology used by this phone system, you connected to it using a “teletype” terminal that you connected to a telephone by clipping the receiver in a cradle. Then you dialed the phone computer. When you connected, it was at 300 Baud. Think of 300 bytes per second, only using audio…. like a fax machine. — It was like connecting using a modem. 300 baud meant that when it typed out the results on the paper that scrolled out the top, you could watch it as it slowly printed out each line. The maximum speed of the terminal was 300 baud.

 

This is the TI Silent 700 Terminal.  We used this exact model of Teletype terminal at the Power Plant

In this picture you can see the cradle in the back where the phone receiver would fit in those two rubber cups.

After many years of going to the lab to connect to the telephone computer to make changes and to monitor the telephone traffic, in 1992 I decided to bring my 8088 computer to work and set it on the desk in the electric shop. We didn’t have our own computer yet. At that time the only people that had computers were office workers and the Shift Supervisor. We had started a computer club and having a computer in the shop was a big help. I had just replaced this computer at home with a 486.

This is a Leading Edge computer.  My father had this one.  An earlier version than the 8088 that I was using.

I had a modem on my computer, so I tried connecting to the telephone computer, and it worked! So, sometimes during lunch when Charles Foster and I were sitting there talking about movies we had seen while eating vegetables from his garden, I would connect to the ROLM computer and just watch the call log. I could see whenever someone was dialing in and out of the plant.

We had a special call in number into the plant that allowed you to make “trunk” calls. This is another term you don’t hear much anymore. You see….. for the younger readers (again)…. long distant calls used to cost a lot of money. You would be charged by how many minutes you were on the call. During the day, it could be as high as $3.00 a minute to call across the country. Amazing huh? Because today, most of you with cell phones and even your land lines (which are rarely real land lines anymore) long distant phone calls are now free with your phone plan.

Yeah, if you wanted to call someone in the next town over, you would have to pay a fee for every minute you were on the call…. That was when AT&T had a monopoly on the phone lines in the United States. Sure, you only payed $7.00 each month for your phone, but you could only call people in your immediate area or you would be charged extra.

A Trunk line gave you access to a much wider area. The Electric company had a trunk line that gave them access to most of Oklahoma. You could dial into a local number that would connect you to the company phone system. Then after entering the correct password number, you could dial access numbers that would take you to another office location in the electric company. Once on that phone system, you could dial to get an outside line, and then dial a local number in that area.

Our plant had three access numbers that allowed you to dial out locally to Stillwater, Ponca City and Pawnee. This was useful when a foreman needed to call people out to work. They could dial into the plant, then back out to one of these other towns and then dial the local phone number of the crew member they were trying to reach without incurring a personal charge on their phone line.

So, here I was in 1992 during lunch watching the phone traffic in and out of the plant (not exactly NSA style, but sort of), when I saw something unexpected. A long string of numbers showed up. Someone had dialed in on the Stillwater trunk, then dialed out to the Corporate Headquarters trunk, then out to Oklahoma City and from there they placed a long distance call to a phone number in the same area code. The prefix on the phone number was familiar to me. It was a Ponca City phone number. I had lived in Ponca City for three years when I had been married, from 1986 to 1989. I knew a Ponca City phone number when I saw one.

I thought this was odd, because it wouldn’t be normal for someone to dial from Stillwater through out plant to Oklahoma City only to call a Ponca City phone number when they could have dialed the local Ponca City access code. Then they wouldn’t have had to make a long distance call which bypassed our trunk call system causing the electric company to be billed for the long distance telephone call.

At the time I was a CompuServe user. This was when the World Wide Web was in it’s infancy. I was still using a DOS computer. When I connected to the Internet, it was either by using my dad’s Internet account from Oklahoma State University where I would use Telnet to access a bunch of mainframe computers all over the country, or I would use the DOS-based version of CompuServe. CompuServe was the king of Internet access before America Online came around and seemingly overnight made CompuServe obsolete.

A screenshot of the CompuServe Program I was using.

A screenshot of the CompuServe Program I was using.

In 1992, CompuServe had a service where you could look up phone numbers and find out whose number it was. Imagine that! Yeah. That was one of the neatest features on CompuServe! That and getting stock quotes. — Like I said…. There was no “www.whitepages.com” online. The only catch to using the reverse phone number feature, was that it was like making a long distance call. It cost money. You were charged by the minute for using the CompuServe reverse telephone number service, with the least amount being a dollar.

So, I bit the bullet and accessed the Phone Number lookup section of CompuServe. I quickly typed in the number. When the name and address of the user popped up, I quickly hit “Print Screen”, and then exited the service. My fee came to $1.00, but at least I knew what number had been dialed in Ponca City.

Charles, Scott Hubbard and I were a little excited by the time Terry Blevins walked into the electric shop office after lunch was over, I told him what I had seen.

When I told Terry the name of the person that had received the long distance call, he recognized the name right away. When I gave him the address, he was sure he knew who it was. The phone number belonged to the Music Director at the Ponca City High School. His son was attending college in Stillwater, Oklahoma.

Well, that sort of cinched it. We had a pretty good idea who had made the call. It was a college student calling home, who had been given the phone number most likely by a fellow student who knew the code to call home in Oklahoma City. So, the only local access code this guy knew was how to dial through our plant to Oklahoma City and back out where he was free (but it was not free for us) to make a long distance call home.

Armed with this knowledge, I headed up to the front office. I went straight to the Plant Manager, Ron Kilman’s office. I told Ron what I had found. I explained in detail how the person had dialed from Stillwater into our plant and then to Oklahoma City and out and then placed a long distance call to Ponca City leaving us with the phone bill. Since it was the middle of the day, the cost of a long distance call was not cheap.

I told Ron that I had used CompuServe to lookup the phone number and that Terry had said that it belonged to the Music Director at the Ponca City High School and that he had a son in college in Stillwater. I was all ready to pounce on this guy. This was a fraudulent use of the telephone service and there were some pretty strict laws then about stealing long distance from someone else.

Ron, being the more level-headed of the two of us thought about it for a minute and said, “What would be the best way to stop this from happening?” — Oh. Well.  I was so intent on catching the culprit, I hadn’t thought about that angle…. “Well….” I said, “We could change the pass code used to log into our phone system. We would just have to tell our supervisors what the new number is.”

Ron asked me what it would take to do that. I told him I could do it in two minutes. We quickly settled on a new 4 digit pass code and I left his office and returned to the electric shop and made the change essentially turning the tables on the Telephone Interloper. I suppose the college student in Stillwater was lucky that our plant manager at the time was the type to forgive and forget.

Three years later the entire electric company phone system was replaced by a new AT&T computer which was managed by AT&T. As you can tell… Technology just keeps moving forward making seemingly really neat new inventions quickly obsolete.

      I still stand in awe at all the talent we had at the plant- never has one place had so many guys of remarkable skill and overall just good people and kind hearted.

Turning the Tables on a Power Plant Telephone Interloper

Originally posted June 13, 2014:

When discussing Telephones at the Coal-Fired Power Plant in North Central Oklahoma, I have to remember that some of my readers have a completely different perspective of telephones than me. My children grew up probably never seeing a real rotary dial phone except in movies or old TV shows. It might be a little hard for them to imagine a telephone being a possible murder weapon. Telephones have come a long way since I grew up in the 1960’s and 70’s.

A Rotary Dial Telephone

A Rotary Dial Telephone

When you turned the dial on a Rotary phone you put your finger int he hole on the number you want to dial and then you swing it around until your finger bumps up against the metal bracket. When you pull you finger out of the hole, the phone sends a rapid succession of pulses to the telephone company telling them what number you just dialed. It was very… well…. tedious and manual…. and not even electronic. It was electric signals and switches. “Mechanical” is the word I think I’m trying to say.

Even the way you received a dial tone was by sending something called a “Ring-to-ground” signal to the telephone company. That would happen when you would lift the receiver off the hook. There are only two wires used to communicate in an old phone and only one of those had voltage on it. when you ground that wire (called the “Ring”) momentarily, the phone company would then send a dial tone to your phone.

You could actually do this on a dead phone line at times when the phone company had shut off your service. On an old pay phone, when the proper coin was inserted in the phone, the coin itself was used to ground the ring wire, thus telling the telephone company to send the dial tone, allowing you to use the phone. In 1983 there was a movie called “Wargames”.

I had learned about how these telephones worked from Bill Rivers just before going to watch this movie. During the movie Matthew Broderick’s character needed to make a phone call at a pay phone but didn’t have a coin. By taking the mouthpiece off of the transmitter, and using a metal pop top he found on the ground, he was able to ground the “ring” wire to the pay phone, and he received a dial tone. There was a good ol’ boy sitting behind me in the movie theater that said, “You can’t do that!” — Being the newly educated smart (-alec) guy I was, I turned around and said, “Yeah. You really can.”

Anyway. This isn’t a story so much about how old phones work. I just wanted to bring the younger readers back-to-date on phones since now they don’t really call them telephones anymore. It is more like, “Smart Phone” and “Cell Phone”, “Mobile Phone” or just “Phone”. The phone in the house isn’t even referred to as a telephone. We now call them “Home Phone” to distinguish them from the actual phones that we use.

Anyway, when I joined the electric shop in 1983, I learned about the phone system. We didn’t use the older Rotary Dial phones at the plant. We were one step up. We had “Touch Tone” Phones.

As I have mentioned in previous posts, we had our own telephone computer at the Power Plant. It was called a ROLM phone system. See the post “A Slap In the Face at a Gas-fired Power Plant“.

To give you an idea of the technology used by this phone system, you connected to it using a “teletype” terminal that you connected to a telephone by clipping the receiver in a cradle. Then you dialed the phone computer. When you connected, it was at 300 Baud. Think of 300 bytes per second, only using audio…. like a fax machine. — It was like connecting using a modem. 300 baud meant that when it typed out the results on the paper that scrolled out the top, you could watch it as it slowly printed out each line. The maximum speed of the terminal was 300 baud.

 

This is the TI Silent 700 Terminal.  We used this exact model of Teletype terminal at the Power Plant

In this picture you can see the cradle in the back where the phone receiver would fit in those two rubber cups.

After many years of going to the lab to connect to the telephone computer to make changes and to monitor the telephone traffic, in 1992 I decided to bring my 8088 computer to work and set it on the desk in the electric shop. We didn’t have our own computer yet. At that time the only people that had computers were office workers and the Shift Supervisor. We had started a computer club and having a computer in the shop was a big help. I had just replaced this computer at home with a 486.

This is a Leading Edge computer.  My father had this one.  An earlier version than the 8088 that I was using.

I had a modem on my computer, so I tried connecting to the telephone computer, and it worked! So, sometimes during lunch when Charles Foster and I were sitting there talking about movies we had seen eating vegetables from his garden, I would connect to the ROLM computer and just watch the call log. I could see whenever someone was dialing in and out of the plant.

We had a special call in number into the plant that allowed you to make “trunk” calls. This is another term you don’t hear much anymore. You see….. for the younger readers (again)…. long distant calls used to cost a lot of money. You would be charged by how many minutes you were on the call. During the day, it could be as high as $3.00 a minute to call across the country. Amazing huh? Because today, most of you with cell phones and even your land lines (which are rarely real land lines anymore) long distant phone calls are now free with your phone plan.

Yeah, if you wanted to call someone in the next town over, you would have to pay a fee for every minute you were on the call…. That was when AT&T had a monopoly on the phone lines in the United States. Sure, you only payed $7.00 each month for your phone, but you could only call people in your immediate area or you would be charged extra.

A Trunk line gave you access to a much wider area. The Electric company had a trunk line that gave them access to most of Oklahoma. You could dial into a local number that would connect you to the company phone system. Then after entering the correct password number, you could dial access numbers that would take you to another office location in the electric company. Once on that phone system, you could dial to get an outside line, and then dial a local number in that area.

Our plant had three access numbers that allowed you to dial out locally to Stillwater, Ponca City and Pawnee. This was useful when a foreman needed to call people out to work. They could dial into the plant, then back out to one of these other towns and then dial the local phone number of the crew member they were trying to reach without incurring a personal charge on their phone line.

So, here I was in 1992 during lunch watching the phone traffic in and out of the plant (not exactly NSA style, but sort of), when I saw something unexpected. A long string of numbers showed up. Someone had dialed in on the Stillwater trunk, then dialed out on the Oklahoma City trunk, from there they placed a long distance call to phone number in the same area code. The prefix on the phone number was familiar to me. It was a Ponca City phone number. I had lived in Ponca City for three years when I had been married, from 1986 to 1989. I knew a Ponca City phone number when I saw one.

I thought this was odd, because it wouldn’t be normal for someone to dial from Stillwater through out plant to Oklahoma City only to call a Ponca City phone number when they could have dialed the local Ponca City access code. Then they wouldn’t have had to make a long distance call which bypassed our trunk call system causing the electric company to be billed for the long distance telephone call.

At the time I was a CompuServe user. This was when the World Wide Web was in it’s infancy. I was still using a DOS computer. When I connected to the Internet, it was either by using my dad’s Internet account from Oklahoma State University where I would use Telnet to access a bunch of mainframe computers all over the country, or I would use the DOS-based version of CompuServe. CompuServe was the king of Internet access before America Online came around and seemingly overnight made CompuServe obsolete.

A screenshot of the CompuServe Program I was using.

A screenshot of the CompuServe Program I was using.

In 1992, CompuServe had a service where you could look up phone numbers and find out whose number it was. Imagine that! Yeah. That was one of the neatest features on CompuServe! That and getting stock quotes. — Like I said…. There was no “www.whitepages.com” online. The only catch to using the reverse phone number feature, was that it was like making a long distance call. It cost money. You were charged by the minute for using the CompuServe reverse telephone number service, with the least amount being a dollar.

So, I bit the bullet and accessed the Phone Number lookup section of CompuServe. I quickly typed in the number. When the name and address of the user popped up, I quickly hit “Print Screen”, and then exited the service. My fee came to $1.00, but at least I knew what number had been dialed in Ponca City.

Charles, Scott Hubbard and I were a little excited by the time Terry Blevins walked into the electric shop office after lunch was over, I told him what I had seen.

When I told Terry the name of the person that had received the long distance call, he recognized the name right away. When I gave him the address, he was sure he knew who it was. The phone number belonged to the Music Director at the Ponca City High School. His son was attending college in Stillwater, Oklahoma.

Well, that sort of cinched it. We had a pretty good idea who had made the call. It was a college student calling home, who had been given the phone number most likely by a fellow student who knew the code to call home in Oklahoma City. So, the only local access code this guy knew was how to dial through our plant to Oklahoma City and back out where he was free to make a long distance call home.

Armed with this knowledge, I headed up to the front office. I went straight to the Plant Manager, Ron Kilman’s office. I told Ron what I had found. I explained in detail how the person had dialed from Stillwater into our plant and then to Oklahoma City and out and then placed a long distance call to Ponca City leaving us with the phone bill. Since it was the middle of the day, the cost of a long distance call was not cheap.

I told Ron that I had used CompuServe to lookup the phone number and found that Terry had said that it belonged to the Music Director at the Ponca City High School and that he had a son in college in Stillwater. I was all ready to pounce on this guy. This was a fraudulent use of the telephone service and there were some pretty strict laws then about stealing long distance from someone else.

Ron, being the more level-headed of the two of us thought about it for a minute and said, “What would be the best way to stop this from happening?” — Oh. Well. I was so intent on catching the culprit, I hadn’t thought about that angle…. “Well….” I said, “We could change the pass code used to log into our phone system. We would just have to tell our supervisors what the new number is.”

Ron asked me what it would take to do that. I told him I could do it in two minutes. We quickly settled on a new 4 digit pass code and I left his office and returned to the electric shop and made the change essentially turning the tables on the Telephone Interloper. I suppose the college student in Stillwater was lucky that our plant manager at the time was the type to forgive and forget.

Three years later the entire electric company phone system was replaced by a new AT&T computer which was managed by AT&T. As you can tell… Technology just keeps moving forward making seemingly really neat new inventions quickly obsolete.

When Enough Power Plant Stuff Just Ain’t Enough

Originally posted March 21, 2014:

As a young novice Power Plant Summer Help, I had watched seasoned Power Plant Men measure the distance between two points by walking between them and multiplying the number of steps by two. At first I wondered how they could be sure that their strides were all exactly two feet apart. Because the end result of these actions usually came out pretty close to their estimate, over time I began to think that the length of the stride of any respectable Power Plant Man must naturally be three feet.

So, one day when I was working on going to pull a cable from one manhole to the next, I decided I wanted to know the distance before I pulled a lot of cable off of the cable reel. So, I remember that I grabbed the tape measure out of my tool bucket and began walking at as normal of a gait as I could.

I thought if I measured the first step, or even the last step I took that it would somehow be a different size because I wasn’t moving at my normal speed. So. I figured I would surprise myself by just stopping at some random step as I walked between the two manholes.

I don’t know if anyone was watching me as I stood out in the field just north of the two smokestacks, if they were watching me, then they would have seen me pause and stand still for a moment looking down. Start messing around with my feet. Then take a few more steps. Pause once more and do the same thing.

What I was doing was stopping in the middle of my stride when I had just put a foot down, before I lifted the other foot and with my Stanley metal tape measure, I was measuring the distance from the back of one heel to the back of the other heel.

I can’t say that I was too disappointed to find that my stride was not exactly three feet. I hadn’t figured I was completely Power Plant Man material anyway. It turned out to be exactly 30 inches. Or two and a half feet. So, I realized I was about 3/4 Power Plant measured by my stride.

I found that I could easily walk between two points and measure the distance with great accuracy by multiplying the number of steps by two and a half feet. With great knowledge comes great responsibility…. or…um… something like that. Hence the story about how enough was not quite enough.

During the spring of 1992 I was tasked with running telephone cable to various points around the plant. We were going to begin installing a new computer network known as the “Ethernet”. When I first heard the name, I thought they were referring to something in space, where it used to be the belief that there was an area called the “Ether”. But as it turned out, it was the regular network that is still in use today.

Dennis Dunkelgod from Oklahoma City had come to the plant with a bunch of drawing much like they did a few years earlier when they wanted me to install the Dumb Terminals all over the place. (See Post “Working Smarter with Power Plant Dumb Terminals“). This time the diagrams included places where PCs were going to be placed. And where the network server was going to be setup. This required much better quality wiring than the dumb terminals.

So, Dennis saw to it that I had 1/2 mile of 100 pair telephone cable to run from the main plant up to the coalyard. Along with the cable came a box of 25-pair punchdown blocks. I’m sure you’ve seen punchdown blocks in movies when someone is tapping into a phone line, so they go up to these punchdown blocks and hook their handset up to the wires and listen in.

One of the places where I needed to place a number of computers was in the warehouse and the warehouse office. There were no good phone lines running to this building. There were barely enough to take care of the phones that were in the office at the time. So, I needed to figure out how to run the telephone cable to the warehouse which was the southern-most building in the main plant grounds.

Across the drive from the warehouse was the garage. When I looked at the phone panel in the garage, this looked like a good place to tap into the phone system. There were two 25 pair blocks in this building for only one phone. Enough for all the computers in the garage and the warehouse.

All I needed to do now was figure out how to pull a 50 pair telephone cable from the garage over to the warehouse. After looking for the conduit that brought the existing cable into the garage, I was able to determine how it went over to a hand hole at the north corner of the building and then over to a manhole not far away.

A hand hole was a shallow hole in the ground that has buried conduit coming into it. Our handholes had a large piece of concrete covering it.

When I looked at the handhole I suddenly remembered that in during the week of March 21, 1981 I had visited the Power Plant to pick up my application to apply for working as a summer help for my 3rd summer. I was wearing a beard that day when I arrived. While I was in college, I usually wore a beard in the winter to keep my face warm because I rode my bike a lot, and it helped keep my face warm.

I had my friend Tim Flowers with me that day because he was going to apply to be a pre-novice Power Plant Man and work as a summer help also that summer. It was snowing that day and it was almost 4:30pm. Quittin’ Time by the time I had said hello to the many Power Plant Men that I hadn’t seen since the previous summer.

We were heading back out to the parking lot when I heard someone hollering at me. I looked over toward the garage and there was Jim Heflin sitting on a backhoe digging a ditch. He had turned off the backhoe so that I could hear him yelling at me.

A Backhoe

Here is a picture of a backhoe

The Backhoe that Jim was on didn’t have a cab on it. He was all bundled up tying to keep warm. I believe when he pulled down his face warmer, he too was wearing a beard. He said that before he could go home that day he had to finish this rush job to dig a ditch all around the back and side of the garage.

When I returned the next summer Jim asked me if I remembered him digging the ditch in the snow that day in March. I told him I did. Then he said, “Come here.” We walked around the side of the garage, and sure enough. There was the ditch still open leading around the side and back of the garage. He said, “It was such a rush job I had to stay out in the snow digging this ditch before I could go home, and it has been left untouched since then.

The reason I bring this up, was because the ditch he had been digging was for the conduit that went from the handhole around the back of the garage and over to the warehouse. Later that summer the Construction crew from downtown came out to the plant and laid the conduit in the ditch and covered it back up. So, I knew how the cable needed to run from handhole to handhole over to the warehouse. Oh. Before I forget. Here is a picture of Jim Heflin with a beard:

The Splittin' Image of Jim Heflin

The Splittin’ Image of Jim Heflin

So, back to figuring out how to get the cable to that warehouse. I measured how far it was from the punch down blocks to where it went down into the ground. From there I walked with my normal gait (which I knew was exactly 18 inches – remember?) counting my steps.

I measured how many steps it was to each handhole and over to the warehouse. where the conduit came up out of the ground and went into the warehouse. In this manner I calculated that I needed 775 feet exactly.

I figured I didn’t want to use the 100 pair cable. That was a lot more cable than we would ever need for this job, so I went up to Bill Bennett’s office and told him that I needed 775 feet of 50-pair telephone cable to go from the garage to the warehouse. He said that he would order some.

I don’t remember what time it was when I woke up in a cold sweat in the middle of the night thinking that the length of cable was just going to reach the telephone junction box, and not enough to comfortably reach the punch down blocks halfway up the junction box. So, when I arrived at work in the morning I went straight to Bill’s office and told him that I should have ordered at least 800 feet of cable instead of 775, just to be safe. Bill told me that he had already placed the order for 775 feet. It was too late to change it.

I thought to myself… surely when you order 775 feet of cable they will send some reasonable amount, like 1000 feet. Would they really cut it off at 775 feet exactly. So, I told myself it would be all right.

Sure enough. a couple of days later a reel of 50 pair telephone cable showed up in the electric shop. In big numbers written on the side of the real in red marker were the numbers “775 ft.” Oh geez.

Ok. Somehow I was going to have to make this work. Cross my fingers that maybe my stride was only 17 and a half inches now instead of 18 inches and I had measured it longer than it really was.

So, I pulled the cable from the garage, through the manholes over to the warehouse. In order to pull it from the last handhole into the junction box in the warehouse I had strapped some mule tape to it that I had strung earlier through the conduit using a fish tape. I remember going inside and beginning to pull the last bit of the cable to the junction box hoping to see the end of the cable come up out the conduit.

As I was pulling the cable, I could feel the cable beginning to bind up as it was tightening up in the last handhole. I was still only holding mule tape when I couldn’t pull anymore. Meaning that I didn’t have any cable yet.

So, I went back to the garage and pushed as much cable into the conduit that I could and still punch down the wires on the punchdown block. I even lowered the punchdown block in the junction box hoping that the extra foot would help. Then I went to each handhole and pulled the cable from the garage in the direction of the warehouse until it was as tight around the corners as it would go.

I had managed to pull an extra 2 feet or so into the last handhole. Now all I had left was to go into the warehouse and pull the mule tape to see if the cable would reach the junction box. — Suspense. Yeah. I know.

When I pulled the last 2 feet of cable from the handhole into the junction box, the end of the cable came out. But only about 1 foot of cable was in the junction box. A punchdown block is about 1 foot long.

So, in order to be able to punch the telephone cable down on the punch down block, I had put the punchdown block at the bottom of the junction box, right where the cable came out of the conduit. On both ends of the cable, I never had to cut one inch of cable from either end. After making sure I had every inch of cable pulled tight through every handhole, I punched down both ends using the handy dandy Telephone wire punchdown tool.

I told myself that from now on, I was always going to throw in a couple hundred extra feet whenever someone asks me how much cable I need. That was too close! You would have thought I learned my lesson.

Now, 22 years later, I still have the same problem as a business analyst at Dell. Part of my job is estimating how long it is going to take to complete various parts of a project. I always make the same mistake and try to over-analyze it so that I can give a really accurate value. The problem is, that I don’t take into account that things take longer than you would think because of factors out of our control.

My project managers know me well enough to take the number that I give them and add a decent amount of time to my estimates. I even tell them that they should because I always underestimate the time. I always estimate how long it would take me to do it personally and I’m not usually the person that is actually writing the code.

Through the last 12 and a half years while working at Dell, I have never missed a go-live date. Oh. Just like this story, we finish on time, but with little or no time to spare. We are always up to the wire. Beginning right when I said we would and ending on the date we planned. Believe me. Just as I pulled every inch of slack out of that cable that day, we end up doing the same with the progress of our projects.

So, I guess I still haven’t learned to properly pad my estimates to reduce the risk of falling short. I think it has something to do with my personality and the way everything has to be mathematically calculated in my head.

      Hah! my stride (heel to toe) is 3 feet, two strides to the link. That’s what practice does.

      But I have learned to add 10% to everything (nearly), somehow it always gets used. 🙂

      In the early 70s I was an assistant to a surveyor in a large electrical contractors when we tendered for, and won, a contract to rewire a local Town Hall, the unusual thing about the job being that the engineers had specified pyro (fireproof) cable throughout the building, some of which was large three phase stuff and very expensive.

      We scaled up the runs from a 1:100 drawing and placed the orders according to those measurements, each of the large cables being cut specially for that run – every single length was wrong when it was installed, short by several feet.

      It took a lot of measuring on site to realise that the drawings were totally inaccurate, this was a Town Hall that had been built in stone around 150 years earlier and some of the walls were two or three feet thick, on the drawings they looked like standard stud walls.

      Expensive lesson to learn but I kept my job 🙂
