BRI Ports up/down after outgoing calls

[Jan-Hendrik Reichardt]

I got a UC540, using BRI 0/1/0 for my German ISDN. Everytime, I do 2 outgoing calls, the BRI-Port goes up/down. During this time I'm not able to make a call for about 15 seconds, until the Port is up again.

Any ideas?

Some hint that might help (didn't help me tho):

CLi shows this, everytime my described problem occurs:

%MARS_NETCLK-3-HOLDOVER-TRANS: Holdover timer exceeded for Controller BRI0/1/0

Any suggestions how to fix this?

Hi Jan-Hendrik,

It is a long shot, but can you see if your ISDN is set to layer 1 active all the time? You may to need to check this with your carrier...

Cheers,

David.

Thanks for your advice, but I already fixed it myself. I only needed to adjust my "network-clock-participate" settings.
