Book Description
What is "digital telephony"? To the authors, the term digital telephony denotes the technology used to provide a completely digital telecommunication system from end-to-end. This implies the use of digital technology from one end instru ment through transmission facilities and switching centers to another end instru ment. Digital telephony has become possible only because of the recent and on going 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 and 11 provide the reader with the present status of teler-hone technology in terms of voice digiti zation as well as switching principles. The book is an outgrowth of the authors' consulting and teaching experience in the field since the early 1980s. The book has been written to provide both the engineering student and the practicing engineer a working knowledge of the prin ciples of present and future telecommunication 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. Numerous clients and associates of the authors as well as hundreds of others have provided useful information and examples for the text, and the authors wish to thank all those who have so contributed either directly or indirectly.

Book Description
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.

Book Description
This bestselling book is now the standard guide to building phone systems with Asterisk, the open source IP PBX that has traditional telephony providers running scared! Revised for the 1.4 release of the software, the new edition of Asterisk: The Future of Telephony reveals how you can save money on equipment and support, and finally be in control of your telephone system. If you've worked with telephony in the past, you're familiar with the problem: expensive and inflexible systems that are tuned to the vendor's needs, not yours. Asterisk isn't just a candle in the darkness, it's a whole fireworks show. Because Asterisk is so powerful, configuring it can seem tricky and difficult. This book steps you through the process of installing, configuring, and integrating Asterisk with your existing phone system. You'll learn how to write dialplans, set up applications including speech synthesis and voice recognition, how to script Asterisk, and much more -- everything you need to design a simple but complete system with little or no Asterisk experience, and no more than rudimentary telecommunications knowledge. The book includes: A new chapter on managing/administering your Asterisk system A new chapter on using Asterisk with databases Coverage of features in Asterisk 1.4 A new appendix on dialplan functions A simplified installation chapter New simplified SIP configuration, including examples for several popular SIP clients (soft phones and IP telephones) Revised chapters and appendicies reviewed and updated for the latest in features, applications, trends and best-practices Asterisk is revolutionizing the telecom industry, due in large part to the way it gets along with other network applications. While other PBXs are fighting their inevitable absorption into the network, Asterisk embraces it. If you need to take control of your telephony systems, move to Asterisk and see what the future of telecommunications looks like.
