When calling a particular modem from home on what is otherwise a 
*very* clear line... (I watched the phone company checking it, and
otherwise hear no noise) I still get occasional brief bursts of
noise.  I've been told that this is due to phase shift in the newer
(3 yr old) digital switching system at the local Bell office.  How
exactly does phase shift happen?  Is there a work-around?  Can the
phone company fix it (ha!)?

(this is at 2400 baud; there is no problem at 1200)

I'll summarise resonses mailed to me.


Thanks,

-charles
