Earlier claims from the Bells were that ISDN service would be available to half the nation's business phones by the end of 1992. The report took an optimistic view of the delay, claiming the prediction more than doubles the actual 22.42 percent of the 105.5 million lines where ISDN service was available at the end of 1991. Projections in individual regions range from 21 percent to 87 percent. The first call using the National ISDN standard from Bellcore won't be made until November, however. National ISDN was proposed a year ago to unify the way the technology is implemented in switches by Northern Telecom and AT&T, the leading providers. Both companies announced immediate support for the standard, but software takes time to rewrite, and firms which want the service today still must ask what kind of switch to which they're connecting. Generally, regular ISDN business lines, called "Basic Rate Interfaces" in the trade, cost 30 percent more than analog phone lines, offering two digital channels of up to 64,000 bits/second each and a 16,000 bit/second signaling channel, which can be used for voice, fax, data, or video conferencing, as required. The new document also includes plans of Cincinnati Bell Telephone Company, Rochester Telephone Company, AT&T, and MCI, as well as testing programs for ISDN telephones, computers, and other ISDN end-user equipment.
