following up a message from Bob Juge to Gene Lowry:
 BJ> Also, if one x2-enabled I-Modem calls another x2-enabled I-Modem,
 BJ> they can do either ISDN (64K/64K) by default _or_ synchronous x2
 BJ> (64K/64K) by having one of the I-Modems force an analog call.  Why
 BJ> would you want synchronous x2 instead of ISDN? Because USR's
 BJ> implementation of ISDN v.120 does not support data compression, and
 BJ> x2 does.
Replace "synchronous" with "symmetrical", please.  My brain wasn't awake yet 
:-)
