A comprehensive treatment of the subscriber loop of integrated services digital networks, that is the entire connection from the network to the user's terminal. Focusing on the basic rate network and its widespread penetration and use in the public telephone network, shows how the hardware functions are implemented and examines the software requirements for accessing the network and its services. Also details the benefits of such networks and compares them to other types of networks and technologies, and projects trends into the future of subscriber access technology. Addressed to engineers and engineering managers involved with the design and development of ISDN equipment. Includes a glossary, mostly of acronyms. Annotation c. by Book News, Inc., Portland, Or.
