The #1 Working Reference on SS7--Revised & Expanded Signaling System #7 is the hands-down choice for engineers and network managers everywhere. Travis Russell's Signaling System #7, Third Edition, gives you a bedrock understanding of the signaling network, its architecture, and the protocols used to communicate through it. Accessible even to novices, Russell's guide also provides the technical details, protocol messages, and application examples so fundamentally helpful to developers, engineers, and network planners. Network-switching expert Russell brings his succinct, logical style to: * New coverage on VoIP and SS7-TCP/IP interactions * Solutions to protocol issues in migrating telecom to the Internet * Details on SS7 in broadband and cellular networking * Lucid explanations of protocols and network entities, with hands-on examples and applications * Clarifications of ANSI standards and Bellcore publications, with model solutions *New information on local number portability * Needed technical data for design and specifications

Your source for the latest terms and concepts used today in the field of telecommunications! The objective of this book is to provide a self-contained quick-reference to telecommunications jargon and facts in a clear concise manner. The unique feature of this book is its illustrated approach. The Telecommunications Fact Book and Illustrated Dictionary consists of two parts: the first part defines the telecommunications jargon related to voice, data, video, electronic, satellite, and fiber optics communications. The second part provides a database for facts and figures related to various facets of the telecommunications field.

As the telecommunication and information field expands and becomes more varied, so do publications about these technologies and industries. This book is a first attempt to provide a general guide to that wealth of English-language publications -- both books and periodicals -- on all aspects of telecommunication. It is a comprehensive, evaluative sourcebook for telecommunications research in the United States that brings together a topically-arranged, cross-referenced, and indexed volume in one place. The information provided is only available by consulting a succession of different directories, guides, bibliographies, yearbooks, and other resources. On the one hand, it is a directory that describes in detail the major entities that comprise the American telecommunication research infrastructure including federal and state government offices and agencies, and private, public, and corporate research institutions. On the other hand, it is a bibliography that identifies and assesses the most important and useful reference and critical resources about U.S. telecommunication history, technology, industry and economics, social applications and impacts, plus policy, law and regulations, and role in the global telecommunication marketplace. No existing guide covers all of these aspects in the depth and detail of this volume.

Optical and wireless technologies are being introduced into the global communications infrastructure at an astonishing pace. Both are revolutionizing the industry and will undoubtedly dominate its future, yet in the crowded curricula in most electrical engineering programs, there is no room in typical data communications courses for proper coverage of these "next generation" technologies. Optical and Wireless Communications: Next Generation Networks covers both types of networks in a unique presentation designed for a one-semester course for senior undergraduate or graduate engineering students. Part I: Optical Networks covers optical fibers, transmitters, receivers, multiplexers, amplifiers, and specific networks, including FDDI, SONET, fiber channel, and wavelength-routed networks. Part II:Wireless Networks examines fundamental concepts and specific wireless networks, such as LAN, ATM, wireless local loop, and wireless PBXs. This section also explores cellular technologies and satellite communications. Eventually, next generation networks will be as ubiquitous as traditional telephone networks, and today's engineering students must be prepared to meet the challenges of optical and wireless systems development and deployment. Filled with illustrations, examples, and end-of-chapter problems, Optical and Wireless Communications: Next Generation Networks provides a brief but comprehensive introduction to these technologies that will help future engineers build the foundation they need for success.
