Abstract
The realization of the intelligent network concept is traced, first in the former Bell System in the early 1980s, and subsequently in the Regional Operating Companies, post divestiture. The history of common channel signaling and the introduction of 800 Service, Calling Card Service, and Private Virtual Network Service are described. The network nodes and operations systems that are the major components of the intelligent network are introduced, and their potential application for a wealth of voice, data, and video services is suggested. The next generation of the intelligent network, called the advanced intelligent network, which through its service-creation capabilities holds promise for rapid service development and a cornucopia of customized services, is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
