Digital phone set problems

[jimc35]

The issues I am having with some digital sets are not related to the Nortel switch itself but the cabling involved. With that said here is my issue. I manage a Opt 81C at a military facility where the Nortel is located in one building and the entire base's phone service feeds from that building. The digital sets I have are at a separate building about a 1/4 mile from the switch. I get power to the sets ( I can press the program button and change features) but I cannot get the time to come up nor can i get any of the buttons to work. The weird thing is some digital sets are working fine but others are not in this building. This building's cables multiples with another building nearby and I am curious as to whether that is the reason but not sure. Distance is not an issue since I have other digital sets working just fine further away at other buildings. Hope I this makes sense.

Sounds like a cabling issue to me, like the phones are not getting enough voltage or inconsistent voltage. If you take a phone back to an MDF or IDF and connect them to your TIE cable closer to the PBX do they work then?

Can you idu TN and the switch see the Phone? It will reply with serial number, type. etc. . .

NT CODE: NTMN03BA

Reset the cards. I had the same thing happen to me when I had a PBX lose power. Once I brought the cards back up everything worked fine.

What I have found often works: Software "MOV" the TN to another TN, then "MOV" it back again so it is on the TN it started at. It has almost the same effect as outing and rebuilding.

I agree with the cable issue idea. The more cable on a line, the more resistance you have. This higher resistance equals to an additional cable length problem. 1500 feet is okay, but with the added cable going in other directions, adds up to more cable. Maybe 2500 or 3500 feet? Remove those "multiple" connections and try it. Or, you might want to look at the MCK extenders. They work.
