Abstract:

This book provides a comprehensive functional description of the Defense Communications System, hereinafter abbreviated as DCS. The description of the DCS and analysis of the system operation constitute a specificatation for formulation of computer programaram design plans. The function and operations of various types of DCS switching centers are examined in detail, with particular emphasis on the store and forward switching systems. Both manual torn tape and automated switching methods are described from the standpoint of a computer simulation model. Among the automatic store and forward switching systems included here are the ANFGC-30, thehe Plan 55, and the 82B1. In the area of circuittit switching, the manual ringdown, common control and step by step methods are discussed and illustrated by message flow charts and time phase charts. This document does not compare switching systems or discuss their mechanical features, since it is not concerned with details of equipment design. The approach illustrates, through logic and message flow diagrams, the functioning of the various nodes with special attention to the points where queues are to be expected. Author
