Access Networks Technology And V5 Interfacing

by Alex Gillespie

Overview

New interfacing technology allows multiple access networks made by different manufacturers to be attached to the same core telecommunications system, facilitating growth and raising significant regulatory, technical and competitive issues. Access Networks: Technology and V5 Interfacing is the first book to present a unified view of this technology and specifically V5, the global interface standard.

The book examines both the fundamentals and advanced aspects of network access technology, and the implications for the future of access networks, up to soliton transmission and quantum cryptography.

The author organizes the book into two sections: technological issues and interface issues. A comprehensive examination of the V5 interface standard covers its architecture, multiplexing, message formats, signaling, control protocols, PSTN protocol, bearer channel connection protocol, link control protocol and protection protocol.

The book provides separate chapters on advanced copper, optical fiber, advanced optical, and radio access technologies; the powering of access networks, ATM in the access network, and the supported services. Each chapter ends with a summary of the material covered.

This groundbreaking book facilitates a rapid understanding without relying on mathematics. It is an essential resource for both graduate students and telecommunications engineers involved in the selection of new technologies and the design of telecommunications systems and equipment.

Editorial Reviews

Access networks are the complex multiplexing and transmission systems that are being deployed between users of the telecommunications network and the core switching systems. The first part of the treatment deals with transmission over the different physical media, ranging from simple copper pairs to solitons and quantum cryptography; and with general issues related to powering, services and asynchronous transfer mode. The second half describes the V5 interface and introduces the broadband VB5 interface. Annotation c. by Book News, Inc., Portland, Or.
