What research is being done in broadband ISDN? Is it possible to purchase a prototype switch that supports it? Where should I look for more info? Thanks, Jimmy Niemann EDS Research jcn@edsr.eds.com

Of course there's research into it, but that consists mainly of developing applications that can make use of ISDN without being illegal under MFJ. What kind/size of switch were you looking for? If you want a real switch (either CO or PBX), you can call 1-800-NORTHERN (yes, there are one too many digits ...) and ask for information on the DMS-10/ DMS-100/SL-100.

Bellcore (Bell Communications Research, Inc) is making plans for an industry forum on Broadband ISDN to be hosted by US West on May 22 & 23. For additional information on registration, etc. contact: William Rubin, BISDN Product Manager (908-758-2167) 331 Newman Springs Road (Room 2X-421) Red Bank, NJ 07701 or Alan Tedesco, Dist.

Broadband ISDN is a digital "pipe" significantly higher in bandwidth than "primary rate" ISDN. Briefly, there are three types of ISDN access: Basic Rate: two B channels of 64 Kb each and one 16 Kb D channel used for signaling and also capable of packet data transmission. Primary Rate: a 1.544 megabit (DS-1 rate) access arrangement that can be configured in different ways, but in it's most common form consists of 23 B channels of 64 Kb each and one D channel, also at 64 Kb for signaling. Broadband ISDN: A digital rate significantly greater than Primary.

If you are interested in research related information on Broadband ISDN, I recently edited a collection of papers on the subject and that has been published by Artech House Inc. of Norwood, MA. The title of the publication is "Integrated Broadband Networks," order number 425474, and the toll free number of Artech house is 1-800-225-9977 ext. 4002. I'd be happy to provide anyone who needs more information (such as contents of the book etc.) by email. Please send me mail at the address given below. Also, if you're interested in standardization efforts in the United States for Broadband ISDN, the standards body dealing with it is the ANSI T1S1.5 comittee.
