sundance-communications.com/forum Forums TDM Business Telephone Systems Nortel Telephones & Systems CICS 7.0 Lines are disabling

We have a customer who has a CICS working off of the Analog ports an Option 11C over OPX circuits. The lines will randomly be disabled in Maintenance even though we still have the PBX dialtone at the CICS Dmarc. When they are re-enabled, they still wil not come back up unless we power the KSU down. Since the distance on the OPX circuits round trip is about 20,000 feet, we thought we had transmission issues but they measure fine at 34ma and no more than 6db loss. We have changed the KSU, SW and Trunk cards. Has anyone else seen this problem with 7.0? My next step is to go back to 6.1 MR.What am I missing here? Any suggestions would be greatly appreciated. :bang:

The only issue I have with CICS behind any PBX is being able to provide a DS signal to release the lines. CICS doesn't release on silence.

Try changing the loss package to "long PBX" in Lines setting.

Thanks Marv. We have already changed the loss settings.

I figured you probably went that route of loss settings already but it was worth a shot.

I don't have an answer for you sorry.
