Router interface errors

[davidstevens]

I am converting from a public to private sonet ring. I am using ppp multilink to bond multiple Ts. On a 7204 at one location I am using internal clock on the controller interface. The opposite end (1841) the clock source is line (according to ATT specs). The interface (sh int) shows many crc errors, aborts, frame errors, aborts. When I do a sh service-module there are no errors. ATT sees little or no errors. They appear to be bogus errors because the users are not complaining. Is this something I have to live with? Thanks.

If the provider is providing clock on the circuit, both ends need to take the clock from the line. If not then your setup is correct. But it is worth looking at.
