Mike, if I may... Much of what was once the promise of ISDN has been supplanted today by the Internet's delivering on two of its central themes: interoperability and universality. Indeed, the biggest single boost to ISDN came in the wake of the initial WWW craze, itself, but this was only a small fraction of the overall potential that the ISDN folks were hoping for. In other words, the Internet's impact has been such that it obviated many of the cures for ills that once appeared to be the reasons for many of ISDN's capabilities, in the first place. This is not to suggest that ISDN would have succeeded on its own without the Internet, nor does it necessarily suggest that these two models are one-for-one replacements for one another, although there are many overlaps. Since the Internet is capable of accepting just about any protocol you can throw at it, and still deliver on the end-to-end promise, ISDN is now relegated to a great extent, and shares the same space today as, dialup and other last mile data link protocols such as V.34, V.90, Cable Modem, Frame Relay, X.25, ATM, and others more exotic, because the 'net doesn't care whose rules the last mile end links play by. But this was not the original intent behind ISDN's being. It was intended to be an end-to-end delivery platform, demanding of a consistent profile. This fact, in itself, sets it apart from DSL and CableModem, which by definition are not end-to-end, but which were designed for last mile utilization exclusively, from the start. I know that this is not in direct reply to your point, but I thought that I'd throw it up on the board, anyway. FWIW. Regards, Frank Coluccio
