Paperback. Condición: New. Print on Demand. This book provides practical advice and methods for building telephone exchanges. Its author, an experienced telephone engineer, shares insights gained over 14 years in the field to assist readers in developing their own telepony services. The book begins with the process of selecting and setting up equipment, including wire, cables, insulators, poles, and even manholes. The author stresses the importance of planning ahead to avoid costly retrofits and headaches during installation. The topics of grounding, and the use of tools like voltmeters and ammeters are also covered. There's a nice chapter on troubleshooting techniques which is a helpful addition. The author advocates for building a system that anticipates future needs and even includes some conjectural methods that may prove useful. For example, the book suggests the use of a "bi-metallic" wire made from both copper and iron that has yet to be produced. The book concludes with a discussion on the telephone industry and how it might change in the future, emphasizing the need for adaptable design.
