Cisco Voice over Frame Relay, ATM, and IP is a direct complement to the Cisco authorized training course of the same name. Based on the content of the CVoice course, this book provides an intermediate-level treatment of Cisco voice technologies. The overall objective of the book is to teach engineers how to design, integrate, and configure voice over Frame Relay, ATM, and IP of enterprise or managed network services using various Cisco 2600, 3600, 3810, and 5300 multiservice access devices. Coverage of analog and digital telephony fundamentals and principles of voice communications enables readers to determine optimum service selection, equipment, and configuration of a voice-over data network. Network design engineers and network support engineers will find this book invaluable for its detailed voice coverage on Cisco IOS, hardware, and configuration as well as networking professionals pursuing the Voice Access certification or CCIE certifications.
