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 du- ring 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 engi- neers with an overview of the requirements and features of ISDN that will be useful in thedesign, construction and operation of such systems. The author and his six collabora- tors 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 byclear, well-presented, relevant diagrams, and there is a very use- ful annex on the full set of standards relating to ISDN. This is a good book that will definitely be used as a refe- rence over the next few years by many engineers working in the area..." IEEE Computer "ISDN is a slimbut very effective book dealing with almost every aspect of the evolution ofpublic communications net- works...I highly recommend this book to engineerswho 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."

This work constitutes a continuation of the first volume of the source book, published 1989 and which contained the work leading up to, including, and immediately following the Green Paper on the Development of the Common Market for Telecommunications Services and Equipment. The first volume covered the period up to the end of 1988, while this second volume covers regulatory and policy developments in 1989 and 1990.
