"This book is a first introduction to some of the many aspects of the Integrated Services Digital Network (ISDN). It is intended for those who must learn about ISDN, but feel intimidated by all of the technical jargon commonly found in the current literature. This book will define ISDN terms and explain concepts, allowing the reader to better understand the standards and current literature, as well as vendor's implementation and application specifications.
This book will provide broad coverage to explain what ISDN is, define relevant terms and concepts, describe pertinent standards and protocols, and discuss some of the current ISDN issues, services, trials, and products. In that way, it will serve as a first step in the reader's process of learning about the many aspects of ISDN.
It can be argued that consumers are not interested in technology, but rather in solutions to their problems. In data and telecommunications today, these issues are becoming increasingly inseparable. To truly understand all of the available communications solutions and choose the correct strategy for a given environment and application, there must also be some understanding of the underlying technology. This book will help the reader to get started on that understanding of ISDN.
Much has happened in the evolution of ISDN since this book, and the subsequent edition, were published. Not only have "narrowband" ISDN standards, products, and services evolved and matured, but applications have grown and ISDN is finally beginning to realize its promise. Of even more significance, perhaps, is the emergence of Broadband ISDN (B-ISDN) technologies and services. B-ISDN received passing mention in the first edition of this book and at least one dedicated chapter plus prominent mention in other chapters in the second edition; this treatment was pretty much consistent with what details of B-ISDN were know at the time of the writing. In this edition, B-ISDN occupies a significant portion of the book.
ISDN is an important technology and an important evolution for the telecommunications industry. It is also timely and rapidly moving. This third edition adds more up-to-date information about ISDN products and services, and offers a new focus on B-ISDN services.
