Digital Isdn

DSL technologies explained by the experts who created the standards The most complete coverage anywhere: ISDN, HDSL, ADSL, and VDSL The basic infrastructure for the global broadband network of the future is already in place in most homes and offices. Ordinary telephone lines can provide low-cost, high-volume access to the exploding world of telecommunications services that users increasingly rely on. Now, leading experts in the field have come together to share their insights in a single volume, explaining the past, present, and future of all the DSL technologies. Understanding Digital Subscriber Line Technology: Covers the entire DSL family, from ISDN at 144 kb/s to VDSL at 52 Mb/s Details DSL at all layers of protocol, with special emphasis on the physical layer Discusses applications from both provider and end-user points of view Gives an insider's view of the telecommunications standards process Key standards are explained, including transmission line characteristics, data rates, modulation and coding methods, operations procedures, transconvergence layers, protocols, and network architectures. With its inside track and extensive level of detail, Understanding Digital Subscriber Line Technology will be indispensable to telecom and datacom engineers at every level. It also offers a comprehensible explanation of issues in this growing field to managers, marketing experts, and consumers of DSL technology.

This book provides an up-to-date and thorough grounding in the concepts of modern digital transmission. It is written in a pedagogic style, aimed at enabling readers to understand the fundamental concepts and processes. System descriptions are included, however the text also explains the basic techniques of transmission, and includes the necessary mathematical background. The basic processes, such as matched filter detection, pulse shaping, line coding, channel coding, error detection and correction, etc. are described in the central part of the book. Understanding the concepts behind these processes requires a grasp of basic mathematical models, and this is provided in the first part of the book. Finally, to put the processes in context, the third part describes elements of the public switched telephone network. The book is written throughout in a modern, digital context, and is comprehensively illustrated with helpful figures. Although the models (time- and frequency-domain concepts) have wider relevance, they are developed specifically for modeling digital systems. The processes described are those found in current transmission systems, and the description of the PSTN includes an outline of newly formulated standards for the synchronous digital hierarchy (SDH), SONET and for broadband ISDN (ATM). The many worked examples and exercises with solutions will be particularly helpful to students.

Integrated Services Digital Network - Integrated Services Digital Network (ISDN) is a type of circuit switched telephone network system, designed to allow digital transmission of voice and data over ordinary telephone copper wires, resulting in better quality and higher speeds than available with analog systems. More broadly, ISDN is a set of protocols for establishing and breaking circuit switched connections, and for advanced call features for the user.

Broadband Integrated Services Digital Network - In the 1980s the telecommunications industry conceived that digital services would follow much the same pattern as voice services, and conceived a grandiose vision of end-to-end circuit switched services, known as the Broadband Integrated Services Digital Network (B-ISDN). This was conceived in the 1990s as a logical extension of the end-to-end circuit switched data service, ISDN.

Mobile Station Integrated Services Digital Network - The Mobile Station Integrated Services Digital Network (MSISDN) is the mobile equivalent of ISDN. Used as a value, MSISDN refers to the Mobile Subscriber ISDN Number, which is a max 15-digit number.

Digital facsimile equipment - Digital facsimile equipment refers to the modern fax machines which operates on ISDN 64 kbit/s signals and having colour faxing, high speed 3 seconds per page transmission, high resolution graphics, 256 grey scales and may be PC based, high speed fax, Lan Fax etc.
