Synopsis: This introductory book explains how the parts of the public telephone network and how the effectively operate together operates. Many changes have occurred in public telephone networks and this book is the perfect solution for those involved or interested in the operation and latest available telephone systems. While it is common knowledge that Alexander Graham Bell invented the telephone, it is often overlooked that he also invented the telephone network. True, it was not much by today`s standards of a network--just two cone shaped speaker contraptions set up in separate rooms connected by a length a wire--but it was indeed the first telephone network. Also, the concept of a network has changed wildly from the model used for Bell`s historic first call on March 10, 1876. Modern switching, digital transmission, fiber optics, wireless telephony and most recently Internet telephony, are just a few of the many wrinkles that have affected the designs of public network architectures over the last century or so. Network changes have been driven by both technological advancement and commercial aspirations. Public network operators have responded to user demands for faster and more capacious communications, just as they have also discovered the potential of new technologies--fiber, packet switching, software and digital signal processing for example. The network does indeed start and end with the telephone, but the real story of public network telephony lies in between. Therefore, an explanation of public network basic must start with the telephone, but there are many places to go from there. Literally thousands of people who need to understand how public telephone networks operate have found this book and other works of the author Jack Dempsey extremely valuable. Public Network Basics, provides details of the latest technologies and systems used in public networks.

About the Author: Jack Dempsey is just the person to write a book on basic telecommunications. His interests, professional experience and wide array of technical skills and knowledge are the background for this book. He’s also a master teacher who writes logically and understandably and knows how to uncomplicate the always technically complicated world of telecommunications.

Mr. Dempsey had an impressive career before his semi-retirement that spanned 35 years in the telecom field. After receiving his Bachelor of Science Degree, Communications Major; from the University of Illinois, he joined IBM as a Customer Engineer. Following this, he worked at Illinois Bell in a number of rotational assignments mostly related to #5 Crossbar. After an assignment in IBT Transmission Engineering, Mr. Dempsey was transferred to Bell Labs as a member of the technical staff where he further developed #5 Crossbar common control. While on this assignment, he conceived an invention which was later awarded a patent. Later, at Bell Labs he spent a two-year period in a special training program that included rotational assignments working on then avant garde developments at the Labs.

Mr. Dempsey also worked at Illinois Bell as District Marketing Manager of data and training. He later became a faculty member of the esteemed Cooperstown Data Communications Training Program. He held teaching positions in marketing, engineering and plant curricula. He was then transferred to AT&T Headquarters, Data Engineering Section. While there, he was primarily involved in wideband transmission design. After this period with the Bell System, he left to join Xerox.

His initial assignments at Xerox were with the Communications Product Division and he was appointed Chairman of EIA TR 30.2, the committee that produced the Data Interface Standard, RS-232C. Work on this committee also included joint standards development efforts with ISO (International Standards Organization). Mr. Dempsey participated as a member of the U.S. delegation to CCIIT in Geneva a number of times. He also served as Chairman of an FCC Advisory Committee with the task of devising an acceptable arrangement for direct connection of non-Bell hardware to Bell lines.

He was one of the founding fathers of EPSCS, Bell’s enhanced CCSA-like network. During its design phase he worked cooperatively with AT&T in defining this service.

Dempsey was a member of the Telecommunications Dept. of Xerox for seven of his fourteen years with that company. His responsibilities encompassed both voice and data communications.

More recently Mr. Dempsey was Senior National Consultant to Interline, a subsidiary of U S West. In this capacity he was called upon to provide Interline with consultation on a diversity of topics related to telecommunications. In addition, he conducted a number of training sessions.

Mr. Dempsey authored two other books on telecommunications beside this one. When Jack Dempsey isn’t writing books, he relaxes with his wife Barbara. He divides his retirement time between St. Petersburg, Florida and the Canadian wilderness. His hobbies are telephony, photograpy and his personal computer which is always close by.
