Digital Signal Processing in Telecommunications aims to provide a practical insight into the way in which digital signal processing (DSP) technology is exploited across a broad range of telecommunications applications.

It is certain that, over the next few years, data traffic will dwarf voice traffic on telecommunications networks. Growth in data-traffic volumes far exceeds that for voice, and is driven by increased use of applications such as e-mail attachments, remote printing and fileserver access, and the now omnipresent World Wide Web. The growth of data networking to connect computers with each other and with their peripheral devices began in earnest in the 1970s, took off in the 1980s and exploded in the 1990s. The early 21st century will see ever faster, more cost- effective networks providing flexible data access into ever more businesses and homes. Since the 1970s there have been great advances in technology. For the past twenty years the processing power of computers has continued to grow with no hint of slowing - recall the oft-cited Moore's Law claiming that this power doubles every 18 months. Advances in the data networking equipment required to support the data traffic generated have been enormous. The pace of development from early X. 25 and modem technology through to some of the advanced equipment functionality now available is breathtaking - it is sometimes hard to believe that the practical router is barely ten years old! This book provides an overview of the advanced data networking field by bringing together chapters on local area networks, wide area networks and their application.

Mobile systems - primarily cellular telephony - have been the fastest moving telecommunications development to date with a world-wide customer base that in the ten or so years to April 1996 reached 100 million and continues with a current growth rate of 60% per annum world-wide.

The quintessence of decision support systems is that they are designed to assist people in establishing the best course of action in a given situation but not to automate or tell them prescriptively how to achieve a goal.

As a result of that conference a working group was set up, under the chairmanship of Vint Cerf, to propose new protocols to facilitate computer communications. In 1974 the working group published the transmission control protocol (fCP) and the Interworking protocol (lP).

This book is a collection of chapters describing work carried out as part of a large project at BT Laboratories to study the application of connectionist methods to problems in vision, speech and natural language processing.

Customer demand for an ever-wider range of communciations services and exciting new technological options are forcing developments in both the international and strategic planning contexts. This volume surveys those developments in both the international and strategic planning contexts.

Information systems for very large applications present problems of scale which generate the need for particular software design techniques. Computing Systems for Global Telecommunications is essential reading for software engineers working on all types of large Operational Support Systems;

This book covers the evolving telecommunications technology which will allow the telecoms network to carry sound, vision, text and computer signals. It examines both the equipment available today and the future possibilities raised by recent developments.

The quintessence of decision support systems is that they are designed to assist people in establishing the best course of action in a given situation but not to automate or tell them prescriptively how to achieve a goal.

Building on a strong base of established audiovisual conferencing and interactive multimedia services, BT and MCI are leading the way in defining the commercial applications of telepresence that will shape the future of global telecommunication.

Telecommunications today is in the midst of far-reaching changes due to rapid development of new technologies, services and social evolution. This is the first book to model the process of change in telecommunications, including all of the relevant factors.

The book will appeal to both professional engineers and students and researchers in the subject. From an introduction to the basic terminology and underlying techniques, the book moves on to demonstrate the core enabling technologies, with a broad and balanced perspective given for each topic.

The Information Super Highway concept has gained great popularity recently. If the super highway is to be realised it will almost certainly be built mainly using optical fibres. In this book they set out the technology necessary to build the super highway of the future.

Part One focuses on research activities which are extending current knowledge and includes case studies, investigatory applications and prototyped systems. Part Two details experience of using object technology in real developments from BT.

Network Intelligence provides the authoritative guide to the subject and sets this development in telecommunications into the context of other concurrent advances in customer premises equipment, computing and information networking.

For all users and providers of any form of multimedia service, researchers, development engineers, computer providers or users, IT and Information System managers, change managers in business or in the entertainment industry,Multimedia Telecommunications is essential reading.

ATM (Asynchronous Transfer Mode) networks are widely considered to be the protocol for high speed communication systems, both for broadband information highways and for local and wide area networks. This book provides the reader with an overview of the subject and presents the way ATM is being developed.
