Synopses & Reviews
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
* More than 300 graphs illustrating concepts
* Examples from the U.S. network as well as ITU public telephone networks
*An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department.
Review
"...strongly recommended for academic libraries serving electrical engineering and telecommunications programs including those owning an earlier edition..." (E-Streams, Vol. 4, No. 5, 2001)
"...provides the reader with the opportunity to review the entire area of telephony and digital telephony in particular." (New Books and Multimedia, January 2001)
Synopsis
John Bellamy, an expert in the digital communications field, provides an up-to-date revision of his bestselling book. Throughout, emphasis is placed on system level design considerations and explanations are given on why digital technology has supplanted analog technology in telephone networks around the world. Readers will quickly gain a clear understanding of classical communications theory and the implementation of communications equipment and systems.
Synopsis
Hier kommt die umfassend aktualisierte 3. Auflage eines Bestsellers, von dem in zweiter Auflage mehr als 16.000 Exemplare verkauft wurden.
Seit Erscheinen der 2. Auflage 1991 hat sich auf dem Gebiet der Telekommunikation viel ver ndert. Diese Neuauflage tr gt allen Neuerungen und Entwicklungen der vergangenen 8 Jahre Rechnung und nimmt damit erneut die Spitzenposition unter der Fachliteratur ein. Diskutiert werden alle Aspekte der digitalen Kommunikationstechnik und -netzwerke f r Sprachdienste. Dabei handelt es sich jedoch nicht um ein Fachbuch im traditionell analytischen Sinne der Informationstheorie, wenngleich theoretische Grundlagen rein qualitativ und - wenn n tig - quantitativ betrachtet werden. Der Schwerpunkt dieses Bandes liegt vielmehr auf den anwendungs- und betriebsspezifischen Aspekten der Entwicklung von Kommunikationssystemen. Hauptziel ist die Einf hrung in Prinzipien, Terminologie und Anwendungsaspekte, die die praktische Umsetzung beeinflussen. Dar ber hinaus enth lt dieser Band umfangreiche Information zu Datenkommunikationsnetzwerken, soweit es um die zus tzlichen Einrichtung von Sprachdiensten geht.
