Hi all,

i have an as5350 carrying voice traffic normally, but quite often, the E1s carrying traffic go down and come back itself again. The ios in it is a c5350-is-mz.123-6c.bin. On going through the log history, i got the following message:

00:15:39: %CONTROLLER-5-UPDOWN: Controller E1 3/7, changed state to down

Hi,

Check you synchronization.

I suppose you take it from different sources,

so you have such messages

"There are no good clocks in the system"

Konstantin.

i have Tdm-dial-clock configured but this still happens; ie E1s going down every now and then
