It will be impossible to roll out ISDN for residential service without such gizmos, and they'd better have enough battery backup potential for keeping the line running in the event of an AC failure. Your comments regarding ISDN and analog not interacting ever is perhaps the way things will be at bigger corporations, but not elsewhere. The 64000 BPS pipe provided by an ISDN B channel is the same as what your current analog voice circuit gets digitized into in the C.O. today. The only difference in service between an Analog to ISDN converter in your house and running analog to the CO is where the Analog/Digital conversion takes place. There is a big advantage in doing the A/D conversion closer to your house rather than at the C.O. since the analog lines pick up noise without a means for compensation. SLC-96 units provide a similar A/D conversion outside the C.O.
