BCM 400 Errors

I have a new BCM 400 that has been a real pain in the ass. It continues to drop calls. The system has been rebuilt. Base unit has been replaced. Cards replaced. Cables replaced. Service provider has run test for hours on the PRI and all have come back clean. The only thing that remains is my vender Qwest. Soon that too will be replaced.

The system continues to fail.

Critical error 75

Clock control is in free run. This could indicate a problem with the cable connection, or with the signal from the network.

Critical Error 44

Are you aware of the bad batch of DTMs from Nortel? I don't have the PAA handy, but there was a run for a few months in 2004 that would fail like this. Check the date on your DTM and post and I can check it out. Of course your Nortel vendor should know all about this..

The vender replaced the NIU and provides a ground and I've been error free for 24+.

I'll keep my fingers crossed.

I have another strange issue that came about after the OS was patched last week. I have IP phones that hang off XP workstations and connect via ms VPN, the voice path drops out. No dial tone, ring back and can't hear at either end. The strange thing the VM notice works it connects as if it works, then out of the blue the voice path returns with tone etc...

I've ruled out the firewall.

thanks
