[cisco-voip] ISDN BRI: VIC2-BRI-NT/TE log error messages

Wed Dec 12 14:01:49 EST 2007

Hi,

Running under CME 3.3 on a 3640 with VIC2-BRI-NT/TE  in a NM-HD-2V. I have a BRI ISDN line attached . I use ISDB for occasional incoming calls and fax. It appears to work fine (for years now) but I get the following in the log. My regular POTS lines all have noise on them so I assume the BRI does as well. Some days I get no messages other days they happen all the time. However the fact that the interface is going down for seconds at a time, can't be good. See config, q921 debug , and log and below. Any thoughts or help much appreciated.

Best,

leb
