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."
