The present state of development of communication technology is characterized by two features, namely the digital representation of all signals transrnitted and processed, irrespective of information type - voice, text, data or images - and the integration of systems and services, this integration only being completely possible using digital technology. The boundaries between switching and transmission are shifting, and functions are being redefined and redistributed between terminals and communication networks. Multiservice terminals - unlike telephones, teleprinters, video data terminals - are designed to handle more than one information type. Lastly, the communication network allows voice, text, data and video information to be transmitted on the same circuit; the user obtains access to this network via a non­ dedicated "communication socket". The essential features of this Integrated Services Digital Network (ISDN) have been standardized over the last eight years by experts from all over the world under the aegis of the CCITT 1), the international standardizing body of the carriers of public communication networks. All the leading network carriers are working towards ISDN implementation because of the substantial benefits it will offer to users, network carriers and manufacturers alike: Users will obtain additional and advanced services, most of them designated to cater for the growth in non-voice traffic. The ISDN subscriber access will also enable users to operate existing systems more cost-effectively than via various dedicated networks.

From the reviews: Computer Communications "Although the concept of ISDN has been with us now for over a decade, and much development work has been carried out during this period, there are very few comprehensive books available on the subject. This is perhaps one of the best of them. The book aims to provide engineers and potential engineers with an overview of the requirements and features of ISDN that will be useful in the design, construction and operation of such systems. The author and his six collaborators have succeeded in this respect, producing a readable, yet thorough, technical book that can be recommended to a wider audience... Throughout the book the explanations are enhanced by clear, well-presented, relevant diagrams, and there is a very useful annex on the full set of standards relating to ISDN. This is a good book that will definitely be used as a reference over the next few years by many engineers working in the area..." IEEE Computer "ISDN is a slim but very effective book dealing with almost every aspect of the evolution of public communications networks...I highly recommend this book to engineers who are new either to the field of ISDN or to specific ISDN topics. It is clear, concise, and is excellent padding for those tackling the CCITT recommendations."
