Moving T1's from Nortel to Avaya and not working...

[schupp]

I am working a project to remove a Nortel 81C and complete the installation of a 8720.
We move a couple ATT T1's a couple weeks ago without any issues.

Issue
I was told by ATT and the (mad) Nortel guy that the config on the T1's were all the same.
When we moved the 4 T1's last night the d channel came up but the b channels were OOS Far end.
several hours later ATT said that there is a difference with the T1's that wer cut a couple weeks ago and the ones that we tried to cut last night. The T1's from last night were running ESS4 protocol.

Not sure what this means.

Sounds like you need protocol A (AT&T Custom/4ESS) on the ds1 forms for the circuits from last night. The ones from weeks ago must be set at some other protocol.
