Here is my issue.
I have two VWIC cards on a 2811 going to 2 providers.
One E1 is going down with errors. Line code violations blablabla, and sometime just by chaging the time on the CCM.
Do I need to configure clock source internal on both controller or source line on one of them ?
many thanks.

Clock source must be line on both.
You also need network-clock-participate and network-clock-select.

well ,when I have source line on both, marticipate on both and select either the first one or the second one, then I still have the E1 going down with line code violations.
the only "stable" config is internal on both, participate on both, no select.
But in this config, I have slip erros. no big deal but I don't really understand why it does not work with source line.

Sometime strange things happen when multiple clocks are in a router.
If you can prove that one circuit at time is 100% stable and clean with line clock, -participate and -select, but two are not, then it would be matter for the TAC to look at.
