dual router back to back serial connection (2501 <-> 2620)

Thanks in advance.

Is it possible to run a back to back serial connection between a 2501 and 2620?

If so, what cabling would I require?

If not, is there an alternative configuration for the topology below, or should I pickup another 2620?

Purpose: simulate a WAN connection between the two routers.

Reason: one router would be dhcp client for cable modem, WAN serial to second router WAN serial, which acts as gateway for LAN.

Sure, what kind of interface cards do you have installed in the 2620?

If you have a WIC-1T, then you need a DCE to DTE cable, some people sell them on eBay with a buy-it-now for $1.95.

If you have a WIC-1DSU-T1 card, then you'll need a CSU/DSU for the

2501, and the appropriate cabling for the CSU/DSU to the router. Then you hookup the CSU back to back with the CSU card with a cross-over T1 cable (easy to make one).
