Abstract
The ultimate goal of AT&Ts strategy for broadband products and services — an integrated communications infrastructure that will make multimedia communications as ubiquitous and easy to use as traditional telephone service — may be revolutionary in its effects on commerce, education, health care, entertainment, and many aspects of everyday life. But evolution, not revolution, is the path to that goal. Together with its leadership in asynchronous transfer mode (ATM) technology, the cornerstone of multimedia networking, AT&T offers realistic, flexible options for the evolution of today's heterogeneous networks — whether private or public, optimized for data, voice, or video — toward a future technology infrastructure of broadband integrated services digital networks (BISDNs) based on ATM. In surveying some of the major product and service plans of AT&T Network Systems Group (NSG) and AT&T Communications Services Group (CSG), this paper presents a broad evolutionary path for migration to BISDN.
