helo sir,

we have given an ISDN Dial-up(64k) connection to a customer.From our side we r really pumping 64k, but at the end(at customer) we r getting only between 10k-20k only.When we monitor our dial-up connection through performance monitor in WINDOWS NT(clients machine) so many CRC errors have been found(shown by monitor).

Please suggest me how to rectify this problem.

CRC errors are usually caused by noise, either in the line or trouble with the modem

Like  stevenlewis says, first try to swap the modem (or use it from another location), if it proves OK, you have to replace the wiring.

Thank u very much for ur great response.

but still i have another problem. when the customer connect to another ISP, no CRC errors are being generated (but the band width is low (15k-20k) ).So i confused a lot.

So please give me a conclusion.

Please check the grounding of the NT device on the client's side. Without proper grounding, the problem will not be resolved.
