Available in PDF, EPUB and Kindle. Book excerpt: Telecommunications is a major global industry, and this unique book chronicles the development of this complex technology from the electric telegraph to the Internet in a simple, accessible, and entertaining way. The book opens with the early years of the electric telegraph. The reader will learn how the Morse telegraph evolved into an international network that spanned the globe, starting with the development of international undersea cables, and the heroic attempts to lay a trans-Atlantic cable. The book describes the events that led to the invention of the telephone, and the subsequent disputes over who had really invented it. It takes a look at some of the most important applications that have appeared on the Internet, the mobile revolution, and ends with a discussion of future key developments in the telecommunications industry.

Download or read book Digital Telephony Over Cable written by D. R. Evans and published by Addison-Wesley Professional. This book was released on 2001 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breakthrough PacketCable technology will enable cable companies to deliver high-speed Internet access, video, and IP-based residential telephony across the same coax wires. Every major U.S. cable company has committed to deploying PacketCable. It is estimated that 11% of U.S. residential calls will be carried on PacketCable networks by 2005. This is the first comprehensive guide to PacketCable: architecture, components, and implementation. Evans introduces the PacketCable standard, its goals and the business and technical problems it is intended to solve. Next, he shows how PacketCable networks handle each key task they must perform, including network-based and distributed call signaling; provisioning telephony and other services through Multimedia Terminal Adapters; transmission of billing information; interoperability with the classic Public Switched Telephone Network, and more. Evans also shows how the PacketCable standard provides hooks for implementing advanced Quality of Service (QoS) applications. For implementers, managers, and others concerned with providing CATV, broadband Internet, and telephony services over cable networks, and for building IP telephony networks from scratch using shared-access architecture.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
