Do you mean a couple *of* calls? Your description is missing words out.

Where did you get the files?? Been looking for them. Thanks

Thanks for the video context. I saw the setup at VCFMW and just wish I had a little more time to stop and talk. Nice to see some of the work that went into getting ready. Great work!

This was the most impressive part of the entire show. If you need help next year, I'm local to the show

If you are looking for something easier than the 110 blocks. Consider a pair of QKBOX41A 19in rack mount brackets Part: A0352331 These are for mounting two BIX mounts QMBIX10A (250 pair) or QMBIX12E (300 pair) to a standard 19in rack. The Northern Telecom (now Belden) BIX strips provide easy access to bothe the feed crossconnect sides, as apposed to having to remove a full C4 or C5 block on a 110 frame to access the feed side.

I had multiple people tell me during and after the show, "I can't believe how committed they are to the bit!", but of course it's more than a "bit" given the months of engineering and preparation that went into this. The dedication was inspiring.

Impressive! ☎ ❤☎

The phone network running at the show is one of the coolest things about VCFMW! Thanks so much for your tremendous efforts in making it happen!

Hi! My Ion StormPro 30ACi+ inverter also overcharged the battery and didn't last a full 3 years. I am unable to get a new one due to warranty -- can I buy a new cheaper inverter (from another company) to work with the rest of the system?

Coincidentally, I co-op'ed as an outside plant engineer with BellSouth in Tuscaloosa while I was in school there (in electrical engineering). I haven't checked lately, but last I heard, AT&T was using Lucent 5ESS switches in all three Tuscaloosa central offices (Northport, Druid Hills, and Tuscaloosa Main & Toll). They replaced the switch in the Main & Toll office after I graduated (the former clicky beast in that CO was an AT&T [Lucent] of some variety), and for some reason I never had a reason to visit the Northport CO, but I've seen the 5ESS in the Druid Hills office. :)

You know, as you were making that call and saying the phone number out loud, "three...four...eight...", I was thinking, "That's a weird coincidence. That's the same exchange number used by my undergraduate university in Tuscaloosa, Alabama" (I obviously skipped a lot of the video). 😆

Do you have a DMS TOPS operator position terminal?

This is actually an SL-100 PBX, not a DMS-100

That was part of Nortel central office equipment

HI, I have a question to ask you. I have an IBM6182 plotter (HP7550A) and I have connected the RS-232-C cable to the Terminal port (DB25) of the plotter to the COM 5 card of the PC (DB9). I would like to print the *.hpgl files directly via the serial port with the command: "copy nome.hpgl >com5" because I don't have the drivers for Windows 11. I tried but the plotter goes into error and freezes (15: ERROR IN I/O TRANSMISSION). What should I do to make the PC communicate with the Plotter? How do you set the plotter? Can you help me solve and recommend programs, whether for Windows or Linux? Thank you Federico

HI, I have a question to ask you, I hope you can help me. There are three input ports in the plotter: 1 - IEE-488 2 - Computer/Modem DB25 Male 3 - Terminal DB25 Female I used a DB25 Male - DB9 Female > DB9 Male - USB rs232 cable and connected it to port 2. Since it's not plug&play, the PC doesn't see the printer, what can I do? Should I connect the PC with another type of cable? I would be very grateful if you could point me to a solution. Federico

Glad you got that fixed and that it was trivial. I am having less luck with my CRT monitor. The power LED actually shuts off the moment a signal isn't detected, and the power build fades away, even though there's still technically some power running through the supply. By design, the monitor is supposed to remain idle with its power LED on, until a source is detected. Unfortunately, the monitor only intermittently detects a source. When it does finally detect it, it powers on fine and displays an image. Finally at this point, its power on/off becomes consistent as far as I know. It's as if the monitor is dodgy when cold but fine to go once it's warm. After left for a while, it's back to square one and I have to do specific power-on procedures in order to get the monitor to hang on and display an image.I am still not sure what the issue is. All the caps I inspected looked physically fine. There is a buzzing coming from somewhere in the monitor, but that could just be some loose coils. I hope it's not a failure with the main board or video signal board.

Post up a couple of TRAVERs so we can see the translations you are using.

So that tap is quite spectacular. But even more is your background noise 😍

Now replaced by a Raspberry Pi running Asterisk.

Worked on telecoms 45years, finally with Lucent as a Transmission Lab manager. My garage has a lot of test equipment and benches.Nice to see a garage being used the right way. A man cave😅. We had a DMS100 a USAF Fairford it was always a fascinating switch.

How do I get this machine?

Amazing video. I worked on DMS500 since mid-90s, kept quite a handfull of documention if you need. Mostly cds. Im retired now but company i worked for 20 years still have 3 DMS running in VA, and im probably will be cLled back for decommission job once all services have migrated to voip.

Thank you for this. Four years later, this video helped me diagnose my memory problems.

I must be getting old. I worked on these at BNR in our captive offices, mid 80s, and wrote some of the LCM and other maintenance software other peripherals, i.e. the double dashes that report card failure on 1/2 the replaceable unit. I can't remember much (PROTEL or other), I went on to other work at Nortel and anyway, so long ago ... amazing to see this set up in a garage, I wouldn't know how to do any of this anymore (I do remember loading large tapes of test software) in lab shifts that were sometimes only available at midnight ... blast from the past. Thankyou.

The network module slots are based upon 32-bit PCI bus running at only up to 25MHz due to the less ideal transmission line characteristics of the extra connectorization. The next generation jumped to PCIe. It’s quite possible that I might have EEPROM data as I have most every module and card.

I believe that you bought the AMP CHAMP butterfly tool rather than Amphenol’s. They are plug compatible, but have entirely different insulation displacement mechanisms. I bought one of these new in the mid 80’s to work on 1A2 key systems that were largely abandoned after divestiture. I still have it in it’s hard plastic shell case along somewhere in storage. There are other sizes such as 24-pin for HP/IB, 36-pin for Centronics parallel printers, and 64-pin used on some channel banks to bring out all 28 T-1 TX or RX pairs of a T-3.

Amazing..

I heard "vampire tap' in Netflix series 'Archive 81'

Is it possible to go from this to rj45?

Just came across this. Were you able to find the documentation that you were looking for?

Used to hack those all the time

Me: Just flip all the switches on at once....what's the worst that could happen? 🤣

I was inspecting a live DMS 100 in Norfolk, VA, USA on Dec 13, 2023. I will be removing the switch in February 2024. I have been removing CO switches worldwide since 1985. Presently, I am mining buried LEAD cable USA-wide. In Nov 2023, pulled 300,000 lbs. in Chillicothe, OH, USA. If anyone knows of abandoned buried cable (LEAD or Stalpteh) I would be interested. Also, interested in CO switches coming up for removal worldwide.

Sweet, I used to patch these and a handful of others.

We only just replaced our Meridian, quite the throwback here.

Looks just as complicated as starting up an airliner.

i connected with many DMS-100s when I worked at the NOC @DFW. Never physically worked on one. More intuitive than a GTD5.

Woah that's awesome that you have this. We still have many in operation throughout the company, I only monitor and occasionally do programming, but never seen one be started up from scratch that's really cool.

I kept expecting to hear HAL's voice at some point during the power up.

My god, seeing this power up sequence, I understand the expertise my former colleagues had. I was one of the last "new hires (2006)" during the CVoIP transition from TDM and the last soldiers standing were older and extremely intelligent. I learned so much but never saw what they had to know. This is what they did in the back of 18 wheelers when hurricanes hit and they drove "ER trucks" to site. Loading specific site configs onto these things, powering them up to provide 911 and emergency call services to devastated areas. Wow.

Gripping

22 yrs and going working on the DMS 100.

What is the tool's name?

Yeah, that white string can be used to pull back against the jacket to open it up to the spot you need to expose the color strands. I'm looking to repair several of these cables, just bought the same tool you have, now I need to find bundles of male/female ends. Thanks for the tips on how this tool works.

Cool! I remember the first time I mop-booted a VAX - a VS2000 back in 1997 or 98

Been a few years now - How did the replacement inverter work for your dad ? I assume the SEC America inverter?

Oah boy! I've made off thousands of these frigging things!! We had one building with 63 base-5 segments - all running around in different locations... Pre-VLAN, pre-TP.. Urgh..

Debian OS with minicom FTW! Sooooo much better than windoze!

kames tool strips the jacket properly... it's basically a rotating tool that holds itself onto the round jacket and you spin it around the circumference . It has an adjustable blade that cuts into the jacket as you spin it around. Very efficient quick and high quality if you get the right tool... I think places that sell industrial electrical wire tools and such sell them. I bought mine from a place called gerrie electric in canada
