Yes, they are ISA and non-Win, but they are Rockwells. Look in
http://www.o2.net/~gromitkc/20000307a.html for the lowdown.
AOPEN makes a Texas Instrument model, which is probably good,
its is the FM56PVS-T (the -T is the critical part and makes it
a TI chipset modem, hopefully with the V90/X2 protocol. If so,
it should be good).
Non-Win Rockwells work, but they are not good performers. They
have aggressive speeds, usually a notch or two higher than they
should for given line conditions. They get LOTS of retrains
which I can see on my logs here. They frequently disconnect
with "lost carrier" in my logs. Retrains are bad, because it
means the modem is spending most of its time resending data that
had errors. The Connect speed may be 52,000 vs 46,666 for a
USR/TI, but the lower speed modem will pass MORE data bytes in
a given time.
There are also lots of other bugs that plague Rockwells.
On the server end, Rockwell digital modems at the ISP end do
not work well with Channelized T1 service using D4/AMI
signalling,and that is about 50% of the phone switches in the
USA. The US Robotics make great consumer modems but are just
terrible for an ISP, although the later revisions seem to be
working better. At one time there was a class action suit
about it, if I recall. The Lucent digital modems, like I use
here at Nook Net seem to be the most robust of the lot. I
tried equipment from Ascend and Cisco here and simply could
not make it work above 31,200. Cisco tried valiantly with
their AS5200....no dice. My Lucent Portmasters PM3 do fine.
On the Analog end, I use a number of US Robotics couriers,
and they do real well too. In one village I was kinda cheap
and used US Robotics sporsters 33.6 data fax modems, and
they work well too.
