Communication Switching Architectures for Business, Industry, and Government

  • A. E. JoelJr.
Part of the Applications of Communications Theory book series (ACTH)


Perhaps no area of communication application has successfully introduced into operation so many innovations as switching for business, industry, and government sectors. Much of this advancement has occurred as a result of the introduction of digital switching into this market in the United States. This occurred in 1973, several years ahead of digital switching in the U.S. public network (1976). These innovations are not only in the services area but also in the systems architecture.
