Nars/Bars question.

You absolutely positively cannot use SL1 protocol when connecting to a Non-SL1. SL1 is a proprietary Nortel Protocol. You would probably want to try using NI-2, QSIg if you've got it.

This BUG
BUG1369
Loop # out-of-range in BCH_TO_TN.?

Is pretty common with wrong protocols. It is saying, that it cannot determine the B-Channel to TN coorelation. With SL1 protocol, the PBX wants to send or receive Explicit Signalling,meaning, When you send me a call, tell me which Interface ID (IID) and which B-channel to set the call up on. When I make a call, I'll tell you where I am sending the call when I make outbound calls.

The bug message is inferring, that Implicit signalling is occuring and the M1 does not know what to do. If you do an DCH trace, you will see something to the effect of
DCH 16 IMSG SETUP REF 0000842F CH 0 TOD 16:39:02 CK 0019DCE0 on inbound, Notice the "CH 0". If you do a full hex dump, there are octets that can be decoded if Implicit or Explicit signalling is being used.

You won't need to go that far however, since we know off the bat that its a protocal issue.

Heres a hint for everyone:
If you see this bug, when you are connecting to a DMS, tell the guy/gal in the CO to add SL1PROFL to table LTDEF.
It looks like this

TABLE LTDEF:
DALLSL1 1 B
PRA 48 48 24 24 NTNAPRI V1 SL1PROFL (NOPMD ) $
