R5 is the DCE end of the link per our hardware configuration.
You can verify this with the "show controllers serial" on the command
line. In most network designs what you would see is the router
connected to a CSU/DSU which provides the clocking for the link and the
router would be the DTE end. In this case for the practice lab topology
the routers are directly connected without a CSU/DSU so one of them must
clock the line. The clock rate itself is arbitrary as long as its not
too fast for the interface (i.e. the interface does not support that
clock rate).
