I was on ISDN for about a year, using a 3Com modem. Compared to dial-up, it was amazing as the connect time was only 3-4 seconds. No more listening to the buzzy connect sequence trying to guess what rate it would negotiate. But something happened to the line and BellSouth could not get it working again. After a couple of rounds of "It passes our tests" and "It still doesn't work" I gave up and went to Time-Warner's RoadRunner cable internet. My ISDN ISP was Uzi Nissan, of nissan-dot-com fame.
