PM3's were pretty solid. PM4's, not so much. They were often problematic
requiring periodic reboots of the entire chassis to keep them sane even
right up through the last firmware release until Lucent killed them off
in favor of their newly acquired Ascend equipment. The team that designed
them were good guys. We used to work directly with them on issues and get
early access to beta releases of new firmware for the PM's, including new
cutting edge protocols such as K56Flex and later V.90. :)

I still have a soft spot for the Portmasters :-). We had rows of PM2's
with US robotics 33.6K sportster modems attached on 8mm tape racks.
Back when a town of 40K people could all connect through 2XT1's and
everyone was happy.
