[darijohorvat]

Hi!

we have used 2651XM for years as a voice gtw with E1 link.

Now, I have replaced it with 2851 router and I`am using the same one E1 link!

now, there is no problems with voice call (everything works fine), but under E1 controller status I see lot of errors!

E1 0/0/0 is up.

Applique type is Channelized E1 - unbalanced

No alarms detected.

alarm-trigger is not set

Have you checked the Network-clock-participate and network-clock on the router also where are you clocking from ?

[darijohorvat]

you mean on router which provides clock? can`t check it, it is provider equipment.

But, nothing was changed on that line (line physicaly remain the same), only my router was replaced!

in configuration I see this command:

network-clock-participate wic 0

Should this be turned off?

[Nicholas Matthews · Accepted solution]

try network-clock-select 1 e1 0/0/0

Should clear that up for you.

hth,
