unsuccessful in reading any of the 1200 baud data I have recorded. I have |
spoke with engineers and techs. Even one of the engineers who designs modems. |
All of them agree that it IS possible, but can't tell me why I am unable to do |
this. I believe that the problems is in my cheap ass modem. One tech told me |
I needed a modem with phase equalization circuitry which is found in most |
expensive 2400 baud modems. Well one of these days I'll find $500 lying on |
the street and I'll have nothing better to spend it on! Ha! Actually, I have |
a plan and that's another file..... |
I should point out one way of reading 1200 baud data. This should work in |
theory, however, I have not attempted it. |
Any fully Hayes compatible modem has a command that shuts off the carrier |
and allows you to monitor the phone line. The command is ATS10. You would |
then type either answer or originate depending on who you wanted to monitor. |
It would be possible to write a program that records the first 300 or so |
characters then writes it to disk, thus allowing unattended operation. |

After numerous calls to several Bell offices, I found the one that handled |
Tymnet's account. Here's a rough transcript: |
Op: Pacific Bell priority customer order dept. How may I help you? |
Me: Good Morning, this is Mr. Miller with Tymnet Inc. We're interested in |
adding some service to our x town location. |
Op: I'll be happy to help you Mr. Miller. |
Me: I need to know how many lines we have coming in on our rotary and if we |
have extra pairs on our trunk. We are considering adding ten additional |
lines on that rotary and maybe some FX service. |
Op: Ok....What's the number this is referenced to? |
Me: xxx-xxx-xxxx (local node #) |
Op: Hold on a min....Ok bla, bla, bla. |
Well you get the idea. Anyway, after asking her a few more unimportant |
questions I asked her for the address. No problem, she didn't even hesitate. |
Of course this could have been avoided if the CN/A in my area would give out |
addresses, but they don't, just listings. Dressed in my best telco outfit, |
Pac*Bell baseball cap, tool belt and test set, I was out the door. There it |
was, just an office building, even had a computer store in it. After |
exploring the building for awhile, I found it. A large steel door with a push |
button lock. Back to the phone. After finding the number where the service |
techs were I called it and talked to the tech manager. |
Mgr: Hello this is Joe Moron. |
Me: Hi this is Mr. Miller (I like that name) with Pacific Bell. I'm down |
here at your x town node and we're having problems locating a gas leak |
in one of our Trunks. I believe our trunk terminates pressurization in |
your room. |
Mgr: I'm not sure... |
Me: Well could you have someone meet me down here or give me the entry code? |
Mgr: Sure the code is 1234. |
Me: Thanks, I'll let you know if there's any trouble. |
So, I ran home, got my VCR (stereo), and picked up another TRC from Trash |
Shack. I connected the VCR to the first two incoming lines on the rotary. |
One went to each channel (left,right). Since the volume of calls is almost |
consistent, it wasn't necessary to stop the recorder between calls. I just |
let it run. I would come back the next day to change the tape. The VCR was |
placed under the floor in case a tech happened to come by for maintenance. |
These nodes are little computer rooms with air conditioners and raised floors. |
The modems and packet switching equipment are all rack mounted behind glass. |
Also, most of the nodes are unmanned. What did I get? Well a lot of the |
logins were 1200, so I never found out what they were. Still have 'em on tape |
though! Also a large portion of traffic on both Tymnet and Telenet is those |
little credit card verification machines calling up Visa or Amex. The |
transaction takes about 30 secs and there are 100's on my tapes. The rest is |
as follows: |
Easylink CompuServe Quantumlink 3Mmail |
PeopleLink Homebanking USPS Chrysler parts order |
Yamaha Ford Dow Jones |
And a few other misc. systems of little interest. I'm sure if I was |
persistent, I'd get something a little more interesting. I spent several |
months trying to figure out my 1200 baud problem. When I went back down there |
the code had been changed. Why? Well I didn't want to find out. I was out |
of there! I had told a couple of people who I later found could not be |
trusted. Oh well. Better safe than sorry. |
************************************** |
Well, if you need to reach me,try my VMS at 415-338-7000 box 8130. But no |
telling how long that will last. And of course there's always P-80 systems at |
304-744-2253. Probably be there forever. Thanks Scan Man, whoever you are. |
Also read my file on telco local loop wiring. It will help you understand how |
to find the line you are looking for. It should be called Telcowiring.Txt |
