Short Description
Telephony is the use or operation of an apparatus for transmitting signals between widely removed points. The field of telecommunications has undergone dramatic changes since the previous edition of this book was published in 1991. This new edition updates all information, providing a comprehensive overview of digital communication technology as it applies to modern telephone systems.
From the reviews of the Second Edition . "The book stresses how systems operate and the rationale behind their design, rather than presenting rigorous analytical formulations . [It provides] the practicality and breadth essential to mastering the concepts of modern communications systems." -Telecommunication Journal In this expanded new edition of his bestselling book, telephony expert John Bellamy continues to provide telecommunications engineers with practical, comprehensive coverage of all aspects of digital telephone systems, while addressing the rapid changes the field has seen in recent years. Bellamy discusses the near-complete conversion to digital technology in telephone networks worldwide, examines both existing and emerging technologies, and explores the intricacies of carrying voice over data networks as well as the use of telephone networks for carrying data for Internet access. He emphasizes system design, implementation, and application, but also correlates the practice to communications theory. With 30 percent new material, Digital Telephony, Third Edition features:
* Clear explanations on how to overcome problems associated with the replacement of old analog technology with new digital technology
* A new chapter on digital mobile telephone technology
* New material on how, data networks support voice communication
* A new chapter on digital subscriber access technologies
