We currently have an E3 line configured between two of our office. That E3 line is up, but from time to time it goes down and after some loop testing with the provider it comes back up.
The E3 controllers of each routers are configured with the command clock source line.
However our provider say that he is not providing the clocking and that we have to configure one of the router to provide that clocking (routers configured in master slave).
We are not sure that this is even possible that the provider is not giving us the clocking since the line is up (and we heve the command clock source line on both end). Did somebody can confirm if the E3 line may be even up with that config?
We want to avoid providing the clocking if the provider is giving it also through the line.
