We've got a PM3 hooked up to a Adtran Atlas 800 which provides ATT-5ESS
emulation and BRI lines, which is making the vast majority of people quite
happy. Very few disconnects. This is advertised as a V90 56k pool.

We've also got a PM3 hooked right into BA PRIs which makes most people
happy, but there are some situations where it won't work. We use NI-2
switch type here to connect to BAs 5ess, which is what we were told to do.
This is advertised as a general purpose dialin number, thus the variations
in speed. We get more disconnects on this than the other PM3. both have
3.8.2. Would this likely be a padding thing? I could hook up a terminal to
the RS232 connector on the T1 linecard and adjust it there, or should I
ask BA to adjust it at the switch. How much adjustment, and which way
works best?

Now, two of our employees have X2 sportsters flashed to V90. One says
columbian is superb and has disc troubles with mug, and one says mug is
superb and has disc troubles with columbian. One of them took a new V90
sportster home and had excellent luck with both. Looks like he'll be
buying a new modem. It could be padding, or more likely, just inconsistent
implementations of V90 from 3com.
Since we're migrating away from analog MP8s and MP16s, which are excellent
33.6 dialin equipment, some customers have had some troubles. Most of them
we resolve. But not all. I was thinking we should start budgeting a
customer retention and happiness fund and use it to sell subsidized modems
to our customers when all else fails. That'd be cool, but then if the next
ComOS doesn't get along with all the modems we just bought, we'd be in a
pickle.
Anyone got any suggestions for a quality external V90 modem that is
reliable and not overpriced? If we recommend them, people will come crying
to us when the stop working if they are not reliable.
I might also keep a pool of 30 analog business lines with the MP8/16
equipment hooked up.
