This book has been written with the intention of helping those who ore concerned with planning, ordering, managing and using telecommunications facilities in connection with their business activities, and who do not wish to obtain a detailed technical and mathematical knowledge of the subject. The various types of telecommunications traffic are analysed without recourse to the underlying theory, and the reader is introduced to the terminology and operation of modern telecommunications systems and networks. Particular attention is paid to the relationship between traffic-carrying capacity and cost, and to the importance of traffic measurement and forecasting as a means of matching equipment provision to demand. The role of performance targets is discussed and the book explains how a comparison between public-network tariff options and the cost of private system and network alternatives can ensure a cost-effective solution to any communications problem. The principles are demonstrated by simple worked examples and a detailed glossary of terms is included.

The author joined the Post Office Engineering Department as an apprentice at Ashford, Kent, in 1943. After transferring to the London headquarters of the Department in 1949, he was involved with various aspects of the development of the UK telecommunications network for some 30 years. During this period he acquired a wide knowledge of the economic principles of switching centre, network and strategic planning. He subsequently took charge of the Performance Evaluation Section of what is now the Performance Engineering Division of British Telecom Research Laboratories, at Martlesham Heath, in Suffolk. In this post, from which he retired in 1986, he was responsible for a wide range of projects, from coordinating the evaluation of the System X public-network switching system to the evaluation of private networks and PBXs.
