Thats great to hear... Here, they do not, at least with PRIs against
a DMS 100 and running ComOS 3.8.

Livingston PortMaster PM-3 ComOS 3.8
System uptime is 24 days 23 hours 19 minutes
Sometimes they stay connected only 5min before dropping, sometimes
upto an hour or two... Almost always with lots of
retrains/renegotiations. This was tested on several different lines
and locations to the same CO in town. My Zoom external running K.Flex
(from my location at home anyways) stays connected indefinitly...
Almost NO renegotiations/retrains. In short, its performance is
stellar. The same Zoom running the v.90 code drops connections (same
cause codes as the other v.90s - User Request - Call Circuit Closed).
Same thing with a Motorola Modem Surfer upgraded to V.90-- same thing
with all HCF modems we have tested running v.90. But the Flex code
works really well using the same line conditions.
ANY of the HCF modems, and no, not just the compaq modems --Acer PCI,
Supra etc. all perform equally as poorly as the other v.90 modems I
have tried. So far the only v.90 that has performed OK has been the
various 3com modems once they are forced to connect at reasonable
speeds...
When you say _seem_ to work well, have you really tested them ? Try
using one for 8 or 9hrs working remotely on a few telnet consoles... I
have a bad feeling you will see what I mean. :-(
For me switching my modems at home is no big deal. Flashing a modem
is trivial... For 7,000 customers of varying degrees of technical
knowledge... I dont think so.
