When show int s0/0 I see that:16 input errors, 9 CRC. I think errors from service provider? because I alway use under 100 kps but still have some errors.

Thanks very much,

Hi,

yes those errors seem to be external to the router. Alternatively, if you are using an external csu/dsu the errors may come from it too not only from the service provider.

Let us know,

When you're able, schedule some downtime for this circuit, and have your provide do some loopback testing on an off-hours time. Simply open a trouble ticket with them, indicating that you're taking CRC errors at the customer-premisis-equipment. 16 input hours per day doesn't seem like alot, but it's still worth checking out, especially since your WAN provider should do this for free.
