Connecting two 2620 router via T1 CSU/DSU via crossover cable

Hi-

I have two 2620 router with T1 CSU/DSU. I am trying to connect both router via a crossover cable. The pins outs are 1->4, and 2->5.

On both routers I am seeing alarm & s0/0 is down/down. On one of the routers I am seeing CD light. I am I missing something or is it bad crossover cable?

Thanks,

JP

Which one is providing clocking?

The pins outs should be:

1->5

2->4

Also, make sure one of the router is providing timing.
