Synopsis

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.

From the Back Cover

PacketCable promises to be one of the most important developments in networking technology to date. The PacketCable™ network, a project managed by the Cable Television Laboratories consortium, is expected to be deployed by all major American cable companies as well as many overseas cable operators. The large-scale PacketCable network enables high-speed simultaneous transmission of digital computer data and telephone voice signals over cable modems and facilitates the widespread deployment of video and voice Internet applications, such as video conferencing, by utilizing cables that are already in place through cable T.V. Developed through the cooperative efforts of numerous cable television operators and telephony and networking vendors, the specifications enable cable modems to compete aggressively with twisted-pair telephony and DSL technology.

Written for anyone with a stake in this up-and-coming field, Digital Telephony Over Cable serves as a companion guide for implementors and managers alike. It provides an accessible overview of more than a thousand pages of technical specifications with in-depth explanations of the most salient features, and offers extensive background on many of the underlying technologies that make digital telephony over cable possible. You will learn how all of these specifications come together to create a complete, functional telephony network running over a shared access medium.

Readers will find in-depth coverage of important topics such as:

• PacketCable architecture
• PacketCable devices
• Security issues, including cryptography, key management, ciphers, and X.509 certificates
• Quality of service issues, focusing on DOCSIS and DQoS
• DOCSIS and MAC specifications for cable modem communication over shared coax
• Network-based call signaling, featuring MGCP and NCS
• Distributed call signaling, featuring SIP
• Network management, covering SNMP, billing, and electronic surveillance
• Internetworking with PSTN

The book concludes with a look into the future of cable modem telephony, including possible changes to current specifications, ownership issues for the MTA, and Fiber to the Home (FTTH) technology.
