[cisco-nas] Lost Fragments

[Voralt]

We have a PRI into a 3640 and are running 128k ISDN connections.  When I
look at "show ppp multi", I see the following.  xxx has lots of lost
fragments and discards and coincidentally, says their connection seems
"slow".  yyy says it is running fine.  Another bit of information is that
user xxx is on LEC A and all of the users on LEC A have lost fragments and
discards and appear to be slow.  yyy is on LEC B and all of the users on LEC
b have no problems and no errors.  We are using LEC C for the PRI.  If we
drop all of the users and make them dial back in, it still follows all of
the users from LEC A.  To me, it seems like an issue either inside LEC A's
network, or between LEC A and LEC C, but I'm not sure exactly where.  We've
contacted LEC C and they say "we see no errors on the PRI, have a nice day".
Any ideas where this error might be originating?  I can't imagine that it is
on the user end.
