Ahh...Ok. Gotcha. I forgot you use the PM3s. We use an
Ascend product here (Max TNT) so we ALWAYS have trouble
with USR products and have to tell clients to turn OFF the
X2 protocol, as it seems they will have NOTHING but
problems connecting unless they disable X2
(www.808hi/56k/trouble2.htm is the site I use now-a-days
for most 56k modem trouble-shooting.)

OUR problem is that our LEC has us on a switch with copper
instead of fiber like the original work order specified,
and the switch we're on is KNOWN to have problems... *SIGH*
We just encourage most of our users to get ISDN, because it
either works or it doesn't. There's no in-between like with
analog modems. Plus they get faster connects & better
throughput with an ISDN router. :-)

I'll keep that in mind. I still don't like WinModems,
though. :-)

:-) Yep. Then again, there's the days you walk in and your
main machine is locked up. :-(
