What is "digital telephony"? To the authors, the term digital telephony de notes the technology used to provide a completely digital point-to-point voice communication system from end to end. This implies the use of digital technol ogy from one end instrument through the transmission facilities and switching centers to another end instrument. Digital telephony has become possible only because of the recent and ongoing surge of semiconductor developments allowing microminiaturization and high reliability along with reduced costs. This book deals with both the future and the present. Thus, the first chapter is entitled, "A Network in Transition." As baselines, Chapters 2, 3, and 10 provide the reader with the present status of telephone technology in terms of voice digitization as well as switching principles. The book is an outgrowth of the authors' continuing engineering education course, "Digital Telephony," which they have taught since January, 1980, to attendees from business, industry, government, common carriers, and tele phony equipment manufacturers. These attendees come from a wide variety of educational backgrounds. but generally have the equivalent of at least a bachelor's degree in electrical engineering. The book has been written to provide both the engineering student and the practicing engineer a working knowledge of the principles of present and future voice communication systems based upon the use of the public switched network. Problems or discussion questions have been included at the ends of the chapters to facilitate the book's use as a senior level or first year graduate level course text.

Introduces all aspects of digital communications, emphasizing voice applications and digitization, digital transmission and switching, network synchronization, control and analysis. Non-technical in the traditional (analytical) sense of communications theory, it stresses the application and operational aspects of communications and system design. Topical discussions in this Second Edition explore new terminology, the advantages and disadvantages of using digital voice networks, the functions and uses of digital radio and fiber optical transmission systems and an analysis of traffic patterns in the digital communications network. New equations and traffic tables, a revised glossary of terms, an up-to-date bibliography and an expanded index enhance and complete this book.

Throughout its history, Understanding Telephone Electronics has been, by far, one of the most popular books on telecommunication electronics in the trade, electronic distribution, and educational markets because of its very simple, direct approach to the technology. In keeping with the distinguished tradition of its predecessors, Understanding Telephone Electronics, Fourth Edition covers conventional telephone fundamentals, including both analog and modern digital communication techniques, and provides basic information on the functions of each telephone system component, how electronic circuits generate dial tones, and how the latest digital transmission techniques work. This new edition of Stephen Bigelow's well-known, widely used text on telephone electronics offers comprehensive coverage of the latest developments in fiber optic technology, the convergence of telecommunications, cable-TV and Internet services, and CTI (computer telephony integration). The authors have made extensive revisions in these and other essential areas, such as business systems, voice mail, phone networking, enhanced services, satellite communications, wireless paging systems, digital communications, and much more to ensure that topics covered are current with the most recent advances in technology. The original Understanding Telephone Electronics has been a "gold standard" reference and training staple for years. Likewise, Understanding Telephone Electronics, Fourth Edition will serve as an essential and invaluable resource for technicians, engineers, students at major universities and corporations, and anyone with an enthusiasm for telecommunication electronics. Provides comprehensive coverage of telephone system functions and the role of the Internet in telephony Updates encompass the trends and advances of the booming telecommunications field, with new chapters on fiber optic technology and the Internet

In network design, the gap between theory and practice is woefully broad. This book narrows it, comprehensively and critically examining current network design models and methods. You will learn where mathematical modeling and algorithmic optimization have been under-utilized. At the opposite extreme, you will learn where they tend to fail to contribute to the twin goals of network efficiency and cost-savings. Most of all, you will learn precisely how to tailor theoretical models to make them as useful as possible in practice. Throughout, the authors focus on the traffic demands encountered in the real world of network design. Their generic approach, however, allows problem formulations and solutions to be applied across the board to virtually any type of backbone communication or computer network. For beginners, this book is an excellent introduction. For seasoned professionals, it provides immediate solutions and a strong foundation for further advances in the use of mathematical modeling for network design. Written by leading researchers with a combined 40 years of industrial and academic network design experience. Considers the development of design models for different technologies, including TCP/IP, IDN, MPLS, ATM, SONET/SDH, and WDM. Discusses recent topics such as shortest path routing and fair bandwidth assignment in IP/MPLS networks. Addresses proper multi-layer modeling across network layers using different technologies—for example, IP over ATM over SONET, IP over WDM, and IDN over SONET. Covers restoration-oriented design methods that allow recovery from failures of large-capacity transport links and transit nodes. Presents, at the end of each chapter, exercises useful to both students and practitioners.
