BCM450 All circuits busy with PRI

[Clyde329]

We've just installed a BCM450 with a pri. Incoming callers are getting this message. the trunks(channels) are idle at the CO and looks like the calls are routed correctly. We checked the BCM and the most channels busy were four,
(1,2,4,23). we determined trunks 1-3 were the problem by monitoring at CO and making calls, so we busied them out at CO. System worked fine for approx 3hrs then same thing happened with trunks 4 & 5, so they were busied out also. No problem since. We have changed DTM card in BCM & pair gain Card in T1 shelf. Any ideas?

Open a ticket with Nortel. They are well aware of the trouble & have come out with a couple of Beta patches that still have not fixed problems wth PRI locking up. Let us hope that they get it fixed soon!!!!!!!!!!!!!!!!!!!!!!!

There is a bulletin related to this that was just released yesterday (or today).

BULLETIN ID: 2008009199, Rev 18

Analysis:
ISSUE: B-channels locking up on PRI
RELEASE: BCM 450 R1
CR: Q02003707
SYMPTOMS: Customers are reporting an intermittent problem with random channels locking up on PRI. The problem
appears to be triggered by incoming calls because it usually happens on the first few channels. Customers rarely report
issues making outgoing calls.
WORKAROUND: None
STATUS: This Condition is currently under investigation by BCM Sustaining designers. A designer patch has been
created and is being tested. Please

Oops - cut off the last bit:

created and is being tested. Please contact Nortel Technical Support and open a case if you believe you have a system
with any of the symptoms above.

Nortel already has the designer core-tel patch they will install for you.
This has fixed almost all issues with 450 and PRI including an issue with my own customer.
