sundance-communications.com Forums More-Phone & VoIP Systems Other Telephones & Systems Now work with an AT&T 5ESS

Ok...I got the "South" part correct.

I lost track of who now owns who, what company acquired another, etc. It seems most companies with a local reference in their name are gone, such as banks that have a state, city/town or region in their name. Southern New England Telephone was acquired by Frontier Communications a few years ago, I'll sometimes still refer to the local telco as SNET.

If anyone still works on the 5ESS or knows - I wonder if there's a way to have an extension, or TN, go directly to voicemail without being on a port, or LEN? We have many spare analog LENs with more to come, but I haven't come up with a way to do it yet. Looked at some main department numbers in the system that go to a menu, those were on LENs.

If the 5Es are going away and the DMS is going away and the GTD-5s are gone....

What's left?

What is running the Network!?!?!?!

Yes the migration to VoIP has been underway for a few years, but due to Covid and other reasons it's been a very slow one.

I helped out a couple times in the switchroom moving cable pairs for the techs. It wasn't with a punch down tool, but a manual wire wrap tool! It's been many years since I've used one of those. Old technology is still here, for a little while at least. I still have a highly modified 1A2 system at home. Behind the living room couch is a 25 pair cable connected to a 66 block. One of several 'IDFs' in the house. Unlike the 5ESS I work with, the home system won't be decommissioned.

Verizon is migrating to packet switching switches. I suppose in areas where FiOS isn't available, Verizon will migrate users to the new switches and reuse existing OSP copper.

To answer Ed's question, AT&T gear that understood NI-1 and NI-2 was never the issue. It was AT&T's older "Custom" protocol that was a very minor hurdle for DMS. The old saw was to ask the switch guy to use NTNAPRI and set the sub-trunk L1 Flag to yes. My stuff would be optioned as DMS100.

We had a guy come fly in to train a couple of new guys who will work primarily on the switch and frame. He asked me to give a basic configuration lesson to them. You can tell he's an old C.O, guy - what I refer to as software and config he calls it 'Translations'.

When I was with Siemens I did a lot of PRI work. NI-2 I believe was the most common D-Channel protocol, I think 5ESS was an option too.

Guilty as charged using "translations". I still have a habit of using terms that aren't as familiar or PC these days: I still say "dike" and "buttset" or might suggest using a "slave printer" or other device when I should say "dedicated" (but that's what we said in the 70's and 80's). "Strap DTR high" or "Strap 'autoanswer' to on" might be better read today as "set". A little off topic. Thanks Keyset6.

You're welcome dagwood systems. I assume you're referring pin 20 on a Db25 connector for 'DTR high', meaning for a modem. I think I could usually get a modem operational with pins 1,2,3,4,5, 6 & 20. 7 was sometimes connected to 1 (ground).I wouldn't consider this totally off topic - I'm told the company that supports the 5E remotely 'dials in' a couple times a day via modem.

The other terms you mentioned I consider common. Even T, R, A, A1, LG, L I understand.
