Britain is set to unveil big ISDN push, at last. After years of pushing back the introduction of ISDN, British Telecom is now planning a great leap forward. Instead of installing 1,500 ISDN basic-rate interface (2B + D) lines in the first year as originally planned, it is telling suppliers that it will install 50,000 lines during 1990. Plans for the following years have been given a similar upward thrust, in line with a memorandum of understanding between European PTTs that ISDN will be made available to 95 percent of business customers by the end of 1992. Currently, the UK has about 1,000 "ISDN" lines installed as part of BT's nonstandard Integrated Digital Access (IDA) service. ==================================== And reproduced from a photocopy that landed on my desk a few minutes ago... Plans for the digital communications era of the future have been unveild by British Telecom with the launch of an advanced service to carry voice, data and pictures. The service, "British Telecom ISDN 2", will pave the way for more high-tech applications such as the picture-phone, ultra-fast fax and high-speed data transfer. ISDN 2 will provide high-speed digital services to branch offices and small and medium businesses. Such services have, until now, been available only to large business sites. The launch follows a 23 million pound order with STC Telecommunications for equipment to provide up to 90,000 lines of network capacity. Nick Kane,BT's Director of Marketing and Sales said: "Our new service, the first ISDN service in the world to conform to the latest international standards, enables a broad spectrum of our customers to take advantage of information technology services previously only available to large businesses. In doing so it will accelerate the introduction of the information society." ================================== Trying to disentangle this from the marketing blurb ... ISDN 2 is "true" ISDN and seems to be based on standard I420. The older ISDN 1 was BT's Integrated Digital Access (IDA) service and was based on the 1980 ISDN standard which got changed (oops...). What interests me is why we all found this out from external sources when we are in the division that is supposed to be supporting the introduction of ISDN. Maybe I'll be able to throw away my modem someday soon... :-) -Pete French. | "The rhythm's gone, British Telecom Research Labs. | The radio's dead.
