Subject: (PM) Up and down PRI, errors, show ISDN questions
>We are having a great streak of luck here. We swapped over to ComOS 3.8.2 a
>week and a half ago with no visible improvement. We haven't lost a customer
>yet....but I have about 5-10 customers that are right on the edge. Now this
>Monday we have all our PRI and our T-1s cut physically at the pole. Bell
>South was suprisingly responsive and got the lines back up that night. Well
>ever since then all hell has broke loose. We were up for a few hours at
>most. I got dropped from home and couldn't reconnect. Once I got to the
>office all the PM's were down. To be more specific I had maybe handful of
>users on when they should have been full. The people who were on were idle
>for the most part. I noticed intermintant error lights on our pairgain
>boxes(PRI+T-1s). I tried getting in to the Pms via PMvision and telnet and
>after rebooting the machines I could get in but I was having trouble
>keeping a connection to them. We finally got everything stable the next
>morning but they seem to be going down twice a day in about 12 hour
>intervals. We have NEVER had a problem like this with out PRI before. I
>want to think that Bell gave us a crappy patch job on the lines. I guess we
>have been spoiled by the fact we never had a problem before and therefore
>I'm not sure how to proceed in showing Bell the lines are bad. I've looked
>at the line0,1 on each PM and I'll attach that below. I also did a sh isdn
>and thats included as well. I've rarely had the need other than curiosity
>to look at these before but I know we did not have these kinds of errors
>showing and thats when the Pms were up for 30+ days at a time. We are
>getting these errors in the course of a day or two. My other question is
>could it be possible that when the lines were severed the Pms could have
>suffered any damage in the ethernet port or other areas?
