A practical, service-oriented guide to large-scale ADSL implementation. From service architecture to applications, standards to business case, Implementing ADSL delivers a complete, up-to-date analysis of what it takes to deploy ADSL. Written by a leading authority in the field, this book will be equally valuable for implementers and decision-makers in both service provider and enterprise IT organizations.

Learn how to estimate ADSL service demand, revenue, capital, and ongoing expenses over the short and long-term; then review the current status of ADSL, G.Lite, and other xDSL techlogies, cable modems, and other alternatives. Next, Ginsburg introduces the ADSL service architecture, outlining an end-to-end service model from the physical layer to the network layer, and addressing crucial issues such as Quality of Service (QoS), security, and IP multicasting. Understand ADSL's physical infrastructure, including splitters and other premises equipment; DSLAMs and other central office equipment; aggregation, access, and core networks; digital loop carriers; gateways; caching solutions; and other key elements. The author also reviews a wide range of ADSL services, including end-to-end ATM virtual circuits, PPP connections, bridging, routing, voice, video, and portals. You'll find seven detailed implementation scenarios, complete with diagrams and configuration listings based on actual deployments: *Residential and corporate Internet access *Telecommuting *Portals and media distribution *Internet wholesaling *Corporate intranets and extranets *Voice over IP *Video streaming Whether you are a network manager, architect, administrator, or engineer, Implementing ADSL brings together crucial information and insight for making the best possible decisions about today's most important access techlogy. 0201657600B04062001
