The Virtual Bookcase Reviews of 'Implementing ADSL':

Reviewer Rob Slade wrote:
ADSL (Asymmetric Digital Subscriber Line), along with many other new and desirable telecommunications technologies, is all too often presented in one of two ways. Either you get "this is new, and you need it!" uninformative boosterism, or you get packet structure specifications for those who need to program the core protocols into switches. It is, therefore, gratifying to find a book that gives you the hard core, and hardware, realities of the system. Chapter one presents the business case for ADSL, based on the usual "Internet users want more bandwidth" model, plus a budget relying on a number of relatively unsupported suppositions and the American telephone network business. Ginsburg does make a very important point all too often lost in other works: ADSL is not a networking protocol as such, but is more akin to a modem specification. Therefore the discussion of encoding methods that begins chapter two is very welcome for those who need to use and understand the technology, rather than merely programming packets. The further material on ATM (Asynchronous Transfer Mode) and alternate options (such as frame relay and Internet Protocol) at the higher layers helps the reader to see how these systems work together. Chapter three outlines the components of the ADSL architecture throughout a network, with the hardware parts mentioned being perhaps more directly related to that topic than the software that is reviewed. Many of the services presented in chapter four actually rely on ATM, PPP (Point to Point Protocol) and other higher layer protocols. Implementation is covered, with detailed configuration examples and screen shots from real products, in chapter five. Chapter six addresses the technology alternatives for providing high bandwidth access to the public. (By the way, a thousand fold increase is 100,000 percent, not 10,000 percent, and a hundred fold increase is 10,000 percent, not 1,000 percent. You're welcome.) This book will, indeed, be useful for those implementing ADSL. Service providers will find a wealth of information that has probably been confined to the engineering department up until now. Users will finally get a chance to understand what ADSL actually is, and where it fits into the rest of the alphabet soup. copyright Robert M. Slade, 1999

Book description:

The 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 overview of what it takes to deploy ADSL. Written by a leading authority on ADSL, this book will be equally valuable for decision-makers and implementers in both service provider and enterprise IT organizations. The author begins with a detailed look at the business drivers and financial models associated with ADSL implementation. 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 technologies, cable modems, and other alternatives. This book 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. Next, Ginsburg 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 technology
