With its promise of high speed Internet access, Asymmetric Digital Subscriber Line (ADSL) techniques are now making their way out of the laboratory and into the general consumer market. This creates the need for telecommunications professionals to have not just an awareness of the technology, but an in-depth understanding of its workings, its potential, and its applications. ADSL: Standards, Implementation, and Architecture provides this knowledge with a detailed treatment of current ADSL standards along with overviews of the implementation, marketing, and architectural issues involved in the rollout of ADSL technology. Beginning with an overview of analog and digital communication-including the difficulties of using existing lines for new services-the author discusses the various types of xDSL transmission methods, the specific transmission, equipment, and hardware requirements of ADSL, and devotes considerable attention to the protocols-ATM, Ethernet, and TCP/IP-used in conjunction with ADSL. The final chapter pulls together all of the aspects of ADSL to address software architecture issues, such as nesting protocols, coordinating signaling control with data processes, special real-time issues, and strategies for the migration to ADSL and beyond. As a collection of topics, ADSL: Standards, Implementation, and Architecture explains why and how ADSL will take its place within the family of data transmission protocols used around the world. It serves as a primary resource for telecommunications professionals who need to know more about ADSL and how they can use it. It also provides technical managers and manufacturers with the ideal reference for an overview of the technology and how it might be applicable to their needs.

Overviews what it takes to deploy ADSL, for decision makers and implementers in both service provider and enterprise information technology organizations. First looks at business drivers and financial models associated with ADSL implementation, then 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 security and IP multicasting. Offers seven detailed implementation scenarios with bandw diagrams and configuration listings based on actual deployments in areas including residential and corporate Internet access, telecommuting, and media distribution.

The digital subscriber line (DSL) industry is expanding rapidly and a technology once thought to be only transitional will soon clear $100 billion in total annual service revenue. From the world's leading DSL experts, Implementation and Application of DSL Technologies builds upon the theory presented in Fundamentals of DSL Technologies

Access to the Internet is an increasing problem in many areas of the world. As the popularity and usefulness of the Internet increases on a daily basis, lack of access to the technology is putting many groups at a disadvantage in terms of better education, better jobs and even in terms of higher levels of civic participation. However, creating a network infrastructure to serve outlying communities and sectors of the population is not straight-forward. This book brings together all the aspects of the problem – technical, regulatory and economic - into one volume to provide a comprehensive resource. It describes the latest technological advances that allow cost-effective network infrastructures to be built, and places them in the context of the applications and services that the infrastructure will deliver. A section on business models and case studies from North American and Europe demonstrate that the solutions are economically and practically viable. This book is essential for anyone looking to gain an understanding of the issues and technology surrounding the access debate. It will be of particular relevance to network engineers/designers/planners at the incumbent operator companies charged with delivering broadband access to as yet unconnected regions. Governments and regulatory bodies will also find this a useful guide to the problems that they may face.

A complete guide of all DSL varieties, this volume also acts as a working handbook of configurations for all Cisco Systems devices. This book covers new standards and deregulation issues, including the recommended G.shdsl standard International regulatory and infrastructure detail for a more global approach.

This module discusses the network services and architectures in the Internet World. topics include network architectures, network connectivity, IP-based networks, broadband networks, wireless networks, and Next Generation Internet.
