T1 Line Problems?

I am wondering if the errors that I'm receiving on my line are acceptable or not. I also want to know why is it that even though all

24 channels of my T1 are initialized available bandwidth reads 1152kilobits/sec?

Thank you, Stanley Louissaint Fluid Designs

the number of errors you are receiving are not acceptable. errors should not exceed 1% of the total number of packets. the key problems I see are the interface resets and carrier transitions. This shows a problem with, the vendor T-1, the cabling form the telco dmarc to the router or the interface card as the most likley culprits. There are some steps you should take to check the current status of the circuit. the last clearing of the interface counters were 2w0d and the last loss of signal was loss of frame 1, last occurred 6d23h . You need to clear counters s0/0 . then check your show interface to see if the errors are still occurring. If the errors are still occurring open a ticket with you circuit vendor. If the errors are not occurring for the next few days, it is possible there was a vendor issue on the network.

Ok, Cogent claims its not their issue. I will try a different wic card as I have another one possibly even a whole new router and go from there.

Stanley Louissa> the number of errors you are receiving are not acceptable. errors

Looks like you have a clocking issue. Change the clocking on the T1 to internal. It is currently configured for line. These statistics should be ZERO 99.99% of the time. The path code violations indicate a clocking problem.
