Digital Networks

  • John C. McDonald
Part of the Applications of Communications Theory book series (ACTH)


A digital switching system rarely stands alone and performs its functions for a closed community. Most frequently, the system operates as a node in a network of switching systems. Such networks are formed by design procedures which trade-off transmission and switching cost to minimize overall network cost. When communications services are to be provided over a large geographic area, these procedures yield minimum cost solutions which involve a multiplicity of switching systems. While previous chapters have described the elements and operation of digital switching systems in their own context, this chapter will describe networks of interconnected digital switching systems.
