Telephone Installation Handbook

Until recently, in many parts of the world, all telephone wiring was the responsibility of the Public Telecommunications Operator, such as AT&T in the USA or British Telecom in the UK. Only PTOs or their agents were permitted to install, alter or remove telephone wiring within premises. Recent legislation means that anyone is permitted to do such work provided the appropriate regulations and codes of practice are followed. This book provides a practical guide to the installation of telephone wiring, from the simple, single extension socket to the Private Automatic Branch Exchange (PABX). First the functioning of the telephone system, with particular emphasis on the Local Loop connecting the subscriber and the local exchange, is described. Then the various sockets, connection devices and cables are shown. The chapter on installation techniques describes how to apply these components. Methods are suggested for implementing various schemes for single-line and multiple-line installations, from planning stage to commissioning. The next chapter deals with fault-finding and fault prevention, including fault-finding tables. Functional descriptions of all common types of apparatus designed to be connected to the telephone system are then given, including simple telephones, fax machines and modems. This chapter includes a wide range of accessories.Finally the necessary tools, test equipment and materials needed by installers are described. The text is supported by an extensive glossary of technical terms, abbreviations and acronyms, and in particular those peculiar to the telephone industry. Other appendices give supplier addresses and useful contacts, as well as providing circuit diagrams and descriptions of a number of telephone-related electronic devices.This book arms you with knowledge of regulations and techniques to help plan and implement telephone installations. Above all, this is a practical book for those intending to make a living from installing extensions and systems, for facilities managers responsible for workplace systems and who need to communicate effectively with installers and maintainers, and for those who prefer to do their own work around the house.Steve Roberts has a lifetime of experience in communications including time in space research with NASA, Cable and Wireless, and latterly in the manufacture of telecommunications equipment. He has written numerous articles and circuit ideas for magazines such as Electronics World and Wireless World. first practical guide to telephone installationdesigned for electricians and other installation engineersdetails and tips, not theory
