Let me understand this better: do you have a back-to-back DB-60 serial
cable from your rouer to the frame switch? If not, please describe the
setup in more detail.
On a lab setup with back-to-back DB-60 serial cables, the speed shows up
on the physcial DCE side of the cable:
R8#sh controller serial 0/0
Interface Serial0/0
Hardware is PowerQUICC MPC860
DCE V.35, clock rate 64000
idb at 0x82479F98, driver data structure at 0x82482284
SCC Registers:

So you are asking how to see the clock rate on the other end (DTE), is
that correct?
