Clocking and all settings are fine - have been working with the telco for over 2 weeks on this.
I just can't imagine that the PRI could lockup the BCM and force a hard reboot this often.

Another thing to consider is to ask the telco to swap the physical pairs that the T is delivered on. Strange how sometimes this makes the problem go away even when Telco says everything tests fine.

System worked for 4 days straight,Dec 27-30, rebooted 2x on Dec 31. Rebooted 2x within the hour on Jan 02/08. - now Bell says they will Change the assignment on the DMS500 - let's cross our fingers. What is the next step?

Would you like me to loan you an external CSU just to see if that would help?

Can the telco put a 24/7 monitor on it for several days? I had a T-1 that was going down sporadically and AT&T absolutely said it was my equipment and I had swapped twice.

I was there one night and by fortune the NIU was in the phone room. As I glanced at it, the lights on one of the 5 T-1s would occasionally flash red/orange and back. I called Special Services and they again grumbled at looking at the circuit. All of a sudden there was an apology and a request to stay on site while they did a fix, the circuit was taking 3000 hits a minute, whatever that meant.

I got to bill them for my time.

With this much time involved you have a right to insist on a 24/7 monitor for at least several days.

the system worked great for 5 more days and then locked up completely. I ended up replacing the BCM with a 3.0 - so far so good. I think the constant rebooting for 1 month really screwed things up. I guess we will never know if the PRI provider was at fault.

Hey Terry, I think it sounds like you owe me beer!!!!!!
