This book includes detailed coverage of digital cable systems -- most existing systems are analog. It shows how to control the return data coming from customers via the coax network. It discusses migrating from a broadcast-only network to one that can handle 2-way traffic.

This book covers the planning, design and implementation of hybrid fiber-optic coaxial (HFC) broadband networks in schools, universities, hospitals, factories and offices, whether they are in a single building or multiple campuses. Within the next few yea

Broadband Cable Access Networks focuses on broadband distribution and systems architecture and concentrates on practical concepts that will allow the reader to do their own design, improvement, and troubleshooting work. The objective is to enhance the skill sets of a large population that designs and builds broadband cable plants, as well as those maintaining and troubleshooting it. A large cross-section of technical personnel who need to learn these skills design, maintain, and service HFC systems from signal creation through transmission to reception and processing at the customer end point. In addition, data/voice and video specialists need to master and reference the basics of HFC design and distribution before contending with the intricacies of their own unique services. This book serves as an essential reference to all cable engineers—those who specifically design and maintain the HFC distribution plant as well as those primarily concerned with data/voice technology as well as video technology. - Concentrates on practical concepts that will allow the user to do his own design, improvement, and trouble-shooting work. - Prepares cable engineers and technicians to work with assurance as they face the latest developments and future directions. - Concise and tightly focused, allowing readers to easily find answers to questions about an idea or concept they are developing in this area.

Fully updated, revised, and expanded, this second edition of Modern Cable Television Technology addresses the significant changes undergone by cable since 1999--including, most notably, its continued transformation from a system for delivery of television to a scalable-bandwidth platform for a broad range of communication services. It provides in-depth coverage of high speed data transmission, home networking, IP-based voice, optical dense wavelength division multiplexing, new video compression techniques, integrated voice/video/data transport, and much more. Intended as a day-to-day reference for cable engineers, this book illuminates all the technologies involved in building and maintaining a cable system. But it's also a great study guide for candidates for SCTE certification, and its careful explanations will benefit any technician whose work involves connecting to a cable system or building products that consume cable services. Features * The much-awaited second edition of an award-winning book, written by leading figures in the cable industry. * Organized to "follow the plant" from signal creation, through multiplexing, transmission, and, finally, reception and processing within consumer's premises. * Focuses on the practical, not the theoretical, and explains concepts and techniques using a minimum of mathematics. * Covers both analog and digital signals, as well as coaxial and fiber-optic broadband distribution systems. * Discusses system architecture in detail, including considerations relating to digital fiber modulation and network reliability. * Explores a wide range of customer interface issues, including analog and digital video reception, consumer electronics, and home networks.

There is widespread concern in the telecommunications industry that public policy may be impeding the continued development of the Internet into a high-speed communications network. In the absence of ubiquitous, high-speed ¡°broadband¡± Internet connections for residential and small-business customers, the demand for IT equipment and new Internet service applications may stagnate. Broadband policy is controversial in large part because of the differences in the regulatory regimes faced by different types of carriers. Cable television companies face neither retail price regulation of their cable modem services nor any requirements to make their facilities available to competitors. Local telephone companies, on the other hand, face both retail price regulation for their DSL service and a requirement imposed by the 1996 Telecommunications Act that they ¡°unbundle¡± their network facilities and lease them to rivals. Finally, new entrants are largely unregulated, but many rely on facilities leased from the incumbent telephone companies at regulated rates to connect to their customers. This asymmetric regulation is the focus of this volume, in which telecommunications scholars address the public policy issues that have arisen over the deployment of new high-speed telecommunications services. Robert W. Crandall is a senior fellow in the Economic Studies program at the Brookings Institution. His previous books include (with Martin Cave) Telecommunications Liberalization on Two Sides of the Atlantic (2001) and (with Leonard Waverman) Who Pays for Universal Service? (Brookings 2000). James H. Alleman is an associate professor in interdisciplinary telecommunications at the College of Engineering and Applied Science, University of Colorado, on leave at Columbia University.

The access network is expected to be one of the major battlegrounds of telecommunications network operators, since upgrades of the existing narrowband access network will be the critical factor in supplying multimedia broadband services in a competitive market. The future broadband access network architecture needs to be flexible enough to efficiently support the provision of a full set of broadband and narrowband services with a wide range of capacity demands. A wide range of broadband access technologies are available. Furthermore, the key issues in the upgrading of the very cost sensitive access network are financial as well as technological, both for incumbent and new entrant operators. Thus, in order to identify minimum-risk introductory strategies the economic viability of access network broadband upgrades needs to be carefully assessed. However, despite the definite need for techno-economic evaluations, very few books have been published in this field. One of the reasons might be that broadband access network upgrading only very recently gained wide recognition as a key challenge for broadband delivery. Secondly, this kind of strategic work and these studies tend to be considered rather sensitive by operators, and thus both results and methodologies are not usually readily available. Thirdly, the work reported in this book in many respects was a major pioneering effort, which quite ambitiously aimed at modelling the whole life-cycle costs and revenue streams of access network upgrades, as opposed to several other efforts, which often are limited to pure investment cost comparisons.
