You can use a back to back cable to simulate a T1 connection. From one of our internal websites -

Connecting a t1 cable to a MIP card .

t1 cable pinouts needed for the MIP card :

1, 3 , 9 , 11

back to back connections

Need to set clock to internal clocking :

follow pins should be connected :

1---to -----9

3---to --- 11

sho controllers slot# t1 on MIP card .

Thanks for your reply. Can I do that with integrated CSU/DSU module or I have to use the old routers that

have no integrated CSU/DSU (like 2500 series router)? Thanks.

router#show controllers serial 0/0

Interface Serial0/0

Hardware is PowerQUICC MPC860 with Integrated FT1 CSU/DSU module

It should work if you cross 1-4 and 2-5 on the rj-45 pins.
