DS1 reset causes remaining DS1s to unregister - 2851

Unanswered Question
Oct 6th, 2009

Hello,

I have a total of 5 DS1's configured on 3 VWIC interfaces. One of the T1's is configured E&M and is used a tie line to a remote PBX. If I have an issue with the tie line T1 and reset it from the CM, it will register like it is suppose to but will cause the other 4 - T1's to unregister. If I reset those T1's(VWIC one and two) they will register and the T1 on VWIC 3 will go down. This will continue until I either reboot the gateway or do a shut / no shut on that interface.

If you have encountered a similar issue, please let me know what had to be done to reslove. - - Thank you...

Haven't seen anything like this on recent IOS. If you're on 12.3 code up to about 12.4(11)T this could be a bug. But 15T and later there shouldn't be anything like this that is a known issue anyways.
