Make a cross-over cable and plug them together. A T-1 cross-over cable is:
A End B
1 to 4
2 to 5
4 to 1
5 to 2

One router needs to be the clock-source Internal and the other router needs to be Network timed.

E1 crossover cable is the same as T1

and life is good, perfect answer. with the tab down on a rj-45 pins 1 and 2 are on the left. in that configeration they number left to right.. on a rj-45 jack, they are green-red (4-5) and white-blue (1-2)
