Re: Weird Outage
An Avaya loopback device (we call them cigars) would have been handy (placed at the DMARC). You send the command to loop it up, then, clear measurements, then list measurements just like you were doing a regular T1 test from the PBX. The interesting part about using these loopback devices is that if the T1 is bad "beyond", the loop won't come down gracefully. So, you have to force it down. But, it's a good indicator.
Also, I have found that list measurement summary (instead of log) is helpful when testing a T1. You just repeat the summary, and, if you have slips or errors, you can see them right away. I have heard people say that they have to wait 15 minutes to see if the "trouble has cleared" when, really, list measurement summary would have told them right away.
