If you're using a back-to-back cable, the DCE will ALWAYS be the router with
the DCE side
of the cable. If you're doing frame-relay, and using 1 router to be the
frame-relay switch, you'd
typically use the DCE side of the back-to-back on the frame-switch for all
routers connected
to the frame-relay switch. You would then set your desired clock rate on
each serial interface.
