An amazing percentage of "private" lines are pseudowires, and neither you nor 
your telco salesdroid can know or tell; even the "real" circuits are routed 
through DACS, ATM switches, and the like.  This is what link encryptors are 
all about; use them.

I would sure be interested in hearing about hands-on operational
experiences with encryptors.  Recent experiences have left me 
with a sour taste in my mouth.  blech!
