No, you don't loopback any of the interfaces. Configure one of the t-1 ports for clock source line and the other as clock source internal. Then check your cable. A t1 crossover is not the same as an ethernet crossover.
A t1 crossover is 1-4 and 2-5. Good luck, ejay ...Cisco Consultant for sale or rent.

I am using a crossover cable connecting the 2 routers back to back. From reading, I understand I need to enable the loopback command, but I have found several and none are working so far. I am using the 2 routers to learn more on router configurations since I dont have much hands on. So I am using them only for practice at home. Thanks for any help. __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
