If you are an engineer working for a telecommunications carrier or Internet service provider, or a manufacturer or student interested in communication technology and digital communications, this comprehensive overview of broadband access technologies is essential reading for you. The book offers you an in-depth understanding of unbundling for voice and data services, and provides expert guidance on hardware considerations and critical communication protocols. You get extensive coverage of the various alternatives for the customer premises, including home networking, single equipment customer premises, and multi-equipment customer premises. Supported with nearly 250 illustrations and including over 120 equations, the book covers a wide range of key topics to help you with your work in the field, from telecommunication networks evolution, existing infrastructure and dial-up modems, and HDSL and ADSL, to the digital subscriber line access multiplexer, protocol architecture, and VDSL. Moreover, the book dedicates entire chapters to the emergent voice over video DSL, Wireless Local Loop, and Optical and EFM Access Networks.
