Re: PRI flapping

Hello Mike,

there was a problem on the T1 line with alarm RAI = Remote Alarm Indicator detected then the alarm was withdrawn and the controller and line came up again.

If this has happened many times you should call the ISDN provider and ask them to verify the line.

Hope to help

Re: PRI flapping

Thanks for the reply. That is what I thought. I have not done a lot of troubleshooting with PRI's and I just wanted to make sure I was not missing something.
