two site connected with E1.

My question is in Remote site,with only 262 packets input,how can it have a 4325 input packets error.What is the problem?What should I deal with it?

packets input = Total number of error-free packets received by the system

input errors = Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so that this sum might not balance with the other counts.

I suggest you refer to the Cisco Command Reference for information on these outputs: (They are very good)

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/finter_r/irfshoin.htm#xtocid13

These errors could be due to any of the above mentioned problems. Check your configurations if it matches with your provider's. Also check the line for any errors. A bit error rate test (BERT) would tell you if the line is good or noisy.
