BCM drops calls unexpectedly

[BobZahn]

We have two recent cases documented where the BCM drops all active calls on the system. Once all the calls are dropped it starts to receive calls again like nothing happened. Any idea what is causing this?

I have activated some new skills this week but they are not receiving calls as of yet.

Do you have T-1 trunking to the BCM? Next time this happens, I'd check the CSU stats in the BCM and see if you were getting any errors on the T-1. If you do have a T-1, I'd suspect something in the circuit.

We have three PRI's going into the BCM. We have discovered a bad channel on one of the digital trunk modules and asked the carrier to turn off the channel we determined was bad.

Could their work cause the PRI's to drop all their calls?

It's possible, depending on how they had to make their changes.
