Huber Since the mid-1980s the idea of the integrated services digital network(ISDN)has become reality. In ISDN voice services with supplementary features and data services with a bit rate of up to 64 kbit/s are integrated in one network. For voice communication and many text and data applications the 64-kbit/s ISdn will be sufficient. Although it is minor as yet, there exists already a growing demand for broadband communication with bit rates from some megabits per second up to approximately 130 Mbit/s [Wiest, 1990](e.g, high-speed data communication, video communication, high-resolution graphics In order to provide the same advantages of isdn to broadband communication users, network operat and service providers, the development of an intelligent broadband-ISDN(B-ISDN)is necessary. The future B-iSDN will become the universal network integrating different kinds of services with their individual features and requirements. B-ISDN will support switched, semipermanent and permanent, point-to-point, and poin to-multipoint connections and provide on-demand, reserved, and permanent services. B-ISDN connection support packet mode and circuit mode services of mono-and/or multimedia type of a connection-oriented or connectionless nature in a unidirectional or bidirectional configuration [Handel and Huber, 1991b] B-ISDN Services and Applications As already mentioned, there exists some demand for broadband communication which originates from business customers as well as residential customers. In the residential area, on the one hand, people are interested in video distribution services for entertainment purposes, like television and high-definition TV; on the other c 2000 by CRC Press LLC© 2000 by CRC Press LLC 72 Networks 72.1 B-ISDN B-ISDN Services and Applications • Asynchronous Transfer Mode • Transmission of B-ISDN Signals • ATM Adaptation Layer • B-ISDN Signaling 72.2 Computer Communication Networks General Networking Concepts • Computer Communication Network Architecture • Local-Area Networks and Internets • Some Additional Recent Developments 72.3 Local-Area Networks The LAN Service Model • Other Features • The Importance of LAN Standards 72.4 The Intelligent Network A History of Intelligence in the Network • The Intelligent Network • Intelligent Network Systems • The CCS7 Network • The Service Control Point • Data Base 800 Service • Alternate Billing Services • Other Services • The Advanced Intelligent Network • Back to the Future 72.1 B-ISDN Manfred N.
