[Guest_imported]

I am need to setup a Cisco 2600 router to another Cisco 1600 router, I already have one internal DSU/CSU 56/64 in the Cisco 2600 and one DSU/CSU external with the Cisco 1600 conected with a V.35 cable. I already have an 128 ISDN line installed P to P.

What is the best sort of config to use for this?

I never do this befeore, and I need the list of material that I need. Ej. one T568A to talk to the router, or one T568B, Laptop, where to find the list of commands that I need, Etc.
