Description

Cutting-edge xDSL: technology, standards, architecture, regulation, and its application. *The state of the art in DSL technology, standards, and architecture *ADSL, HDSL2, SHDSL, VDSL, line unbundling, spectrum management, and more *Voice over DSL and video-on-demand: technical progress and its impact on services *DSL in the home: automating deployment, enhancing security, maximizing revenue *Improved coding techniques, multi-user detection, and other new advances Digital Subscriber Lines (DSLs) have transformed millions of ordinary phone lines into broadband arteries that link homes and businesses to the Internet at megabit speeds. DSL Advances brings together the state of the art in DSL technology and architecture for every technical professional and manager. The authors of the classic Understanding Digital Subscriber Line Technology review the key challenges service providers and equipment manufacturers face now, preview tomorrow's most important standards and technical enhancements, and offer new insights into today's regulatory and business environment.Coverage includes: *HDSL2 and SHDSL: The next generation of symmetric DSL technology *Recent developments in ADSL and standards for line unbundling *Spectrum management standards: "traffic cops" for crosstalk management *Voice over DSL and video-on-demand: technical progress that enhances the business case *DSL networked homes: wired/wireless LANs, shared phone and AC wiring? including both centralized splitters and distributed in-line filter premises wiring *Streamlining deployment: CPE auto-configuration and flow-through service provisioning *Security risks and essential safeguards for vendors, service providers, and users *Future directions, including advanced coding techniques and multi-user detectionshow more

About Thomas Starr

THOMAS STARR, Sr. Member of Technical Staff at SBC Technology Resources Inc., is responsible for development and standardization of xDSL and other new local access technologies for SBC's network. He serves as vice-chair of the T1E1.4 DSL standards working group and vice-chair of the DSL Forum. MASSIMO SORBARA, engineer at GlobespanVirata, is Chair of the T1E1.4 Digital Subscriber Loop Access subcommittee.JOHN M. CIOFFI, Professor of Electrical Engineering at Stanford, holds over 40 patents, including basic patents on DMT, VDSL, and V-OFDM. He spent seven years at Bell Laboratories and three years at IBM, and now advises many leading communications and investment firms. PETER SILVERMAN has represented the DSL Forum's interests to other standards bodies and was its principal architect for CPE management and auto configuration. Starr, Cioffi, and Silverman co-authored Understanding Digital Subscriber Line Technology (Prentice Hall PTR).show more
