back to back T1 connection

Can someone please tell me whether it’s possible to connect two routers back-to-back using integrated T1 CSU/DSU?? I have a Cisco 3620 and a 1720 in a lab environment and trying to connect the serial interface on both routers back-to-back.

If it’s possible could you please tell me where I could find the configuration info.

Thanks in advance.
