Abstract
THE object of this book is to bridge the gap between theory and practice. To students and engineers of telephony it can be commended. The growth of automatic telephony has been marvellously rapid, and few outside the Post Office are aware of the numerous problems that had to be satisfactorily solved before progress could be made. Questions are often set on this subject in technical examination papers, and examples with answers are given at the end of the chapters. ‘Trunking’ in telephony means that branch of the subject that is concerned with the provision and arrangement of the plant required to carry the traffic with a specified grade of service. In the second edition, it would be useful if the author utilised some of the theorems given in the theory of statistics to ‘holding time’, ‘traffic flow’ and busy hour problems.
