Hi, can you show us your running config of both sides, so we can know where would be the problem? cheers, Heiman.

RE: ISDN Port goes to Deactivated mode [7:72022]
I have experienced the same problem and would really like to see what the others have to say. While testing, I put my router with a BRI-1B-S/T card behind a PBX with an NTI card and the problem vanished. This led me to believe that the problem has something to do with the telco. I *think* the telco switch may not be able to detect, in a timely fashion that your isdn line is active, because European ISDN switches normally deactivate layer 1 or layer 2 of an idle isdn line. Removing and re-inserting the cable sort of resets the layers 1 and 2. Has the same effect as typing clear int brix/y on the router.

Re: ISDN Port goes to Deactivated mode [7:72022]
Probably layer 1 and 2 are deactivated by the Telco. It's better to use a dialer interface as backup of a serial line. Then L1/2 stays up. Refer to other ISDN thread as well. If you don't want to do that, try to change the TEI negotiation. Cisco's default is TEI negotiation when the router is powered up. TEI negotiation also happens when you reset your interface. So try to configure TEI negotiation on first call for your backup interface only: interface bri0 isdn tei first-call When the serial goes down, the backup makes its first calls and trigger TEI negotiation. I hope ...
