Voice Port going down and says administrativley down

Unanswered Question
Jun 3rd, 2007

As indicated the voice port goes down / up several times a day as if someone has administratively shut it down and no one has done so. See attachment.

The NM-HDV-1E1-30E= card and the card in the PBX that this connects to have already been replaced. The next thing left is the 2 metre cable between the router and PBX. Customer ays that there has been no H/W or S/W change in router or PBX before the problem started.

I have this problem too.

Hi,

the port goes down each 5 minutes exactly, like if a timer is involved. Does ever stop doing this ? Which IOS are you using? While is up, can you check "show controllers e1" ?
