T1 connectio between cisco and non-cisco router

I have Cisco 2612 with T1 CSU/DSU interface with HDLC. The remote office has Wellfleet router with external Adtran DSU/CSU. As soon as I plug in to telco, I received a lot of input errors. How should I trace this problem?

Re: T1 connectio between cisco and non-cisco router

You need to use PPP encapsulation,

first; HDLC will not work with non-

cisco devices.

If you still have problems after making

that change on both ends, you should

work with your carrier doing loopback

tests to figure out where/if there is

a problem in the circuit.
