I'm looking for a discussion of ISDN, on about the technical level of IEEE Spectrum or CACM. I'm especially interested in how it affects user interface. For example, now that DTMF is not used for signalling (the D channel handles that) can I be sure I'll be able to control e.g. my home answering machine remotely? Now I *don't* want someone to answer this quesion, nor do I want to read the Specifications (which are surely overkill): what I want are pointers to decent summaries, even up to book length. -- ARPA:jrd@media-lab.media.mit.edu Phone: (617)-253-0360

The AT&T Technical Journal (formerly the BSTJ or the BLTJ) had a special issue on ISDN in January 1986, volume 65 no. 1. It describes both ISDN and AT&T's approach to implementing it. The issue also happens to be the first one after they changed the journal from the old staid blue covers to the glitzy new format with lots of color pictures. Back issues are available from AT&T's CIC in Indianapolis at 800-432-6600. Have a credit card (not your calling card) handy. To answer the question that was posed, the terminal interface for ISDN is entirely different from that for an analog telephone, so you can't plug your existing answering machine in directly at all.
