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

Should clear that up for you.

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

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?
