Ok, Here it is.  Hopefully very simple.  The dce think of it as a 
translator it speaks two different technologies at layer one of the osi 
model.  The dce recievies a signal from say a t1, which operates at 
level one of the osi model.  The t1 signal has clock in it.... this is 
derived from a stratom clock passed down through the networks for 
timing...... so you have two dce or csu both operating on the ends of 
the circuit, in the same language using the same beat.... in synch.  All 
of this is fine, but the routers have to take the data that they are 
receiving and pass to the dce.  So this requires that the 
routers....dte... are also in synch... where can they get the common 
signaling from?  you guessed it, the same timing signal can be passed to 
the routers from the csu................ lets try that again, the dte 
can receiving the timing from the dce.  the dce terminates the t1 
circuit, derives the timing and places that on a timing pin/pins to the 
dte.  The dce also derives the data from the t1 and sends that on the 
data pin/pins to the dte
