Download or read book Digital Telephony and Network Integration written by Bernhard E. Keiser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is "digital telephony"? To the authors, the term digital telephony de notes the technology used to provide a completely digital point-to-point voice communication system from end to end. This implies the use of digital technol ogy from one end instrument through the transmission facilities and switching centers to another end instrument. Digital telephony has become possible only because of the recent and ongoing surge of semiconductor developments allowing microminiaturization and high reliability along with reduced costs. This book deals with both the future and the present. Thus, the first chapter is entitled, "A Network in Transition." As baselines, Chapters 2, 3, and 10 provide the reader with the present status of telephone technology in terms of voice digitization as well as switching principles. The book is an outgrowth of the authors' continuing engineering education course, "Digital Telephony," which they have taught since January, 1980, to attendees from business, industry, government, common carriers, and tele phony equipment manufacturers. These attendees come from a wide variety of educational backgrounds. but generally have the equivalent of at least a bachelor's degree in electrical engineering. The book has been written to provide both the engineering student and the practicing engineer a working knowledge of the principles of present and future voice communication systems based upon the use of the public switched network. Problems or discussion questions have been included at the ends of the chapters to facilitate the book's use as a senior level or first year graduate level course text.

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.
