I have a Line Side T1 from an Avaya G3 connected to a Win2000 server with an NMS AG4000 card. Trunkmon shows no errors or code violations and my application works fine.
I move the T1 cable to a Win2003 server with an NMS CG6060 card. the board starts successfully. Trunkmon reports no alarms or slips and the Frame Sync is OK, but code violations occur at a pace of a hundred or so per second. The voice channel works - I can place calls, hear prompts, and select options. The problem that occurs is the NMS card incorrectly detects a disconnect signal at seemingly random times and terminates the call. Any idea why I would not see the code violations on the AG4000 but do see them on the CG6060 with the exact same connection, or how to troubleshoot this issue?

Here are my cg\cfg settings:

Clocking.HBus.ClockSource = NETWORK # NETWORK or OSC

Check the line encoding between your CG 6060 config file and the one used for your AG 4000 card. Make sure the CG 6060 is using the same one.

You've programmed your CG 6060 to get its clock from trunk 1, so make sure that trunk 1 is plugged into the telco circuit and not one of the other trunks.

Double-check your OAMSYS.CFG file and make sure it is booting the correct board-level configuration file. Its an easy mistake to make a revised board-level config file and forget to update OAMSYS.CFG (I know, I've done it).

If none of that works, please post the board-level config file for your AG 4000 card.

Tim,
Thanks for the reply. I actually had 2 CG6060 cards exhibiting this behavior. I installed one that's been working for some time in the lab, and sure enough the problem's gone. Sending the cards that didn't work back to the manufacturer.

Wow! That's interesting. Glad you got it work out, though.
