Chances are that you already have this book in your IT library. But, you probably don't have the 2nd edition of the book. Author Roger L. Freeman has done an outstanding job of presenting telecommunications as the world's must lucrative industry.
Freeman begins by showing you--the telecommunication novice, some very basic elements of telecommunications. Next, the author becomes more definitive in several key areas like the quality of service and telecommunications impairments. Then, he provides the reader with a firm foundation of the analog voice channel. Freeman continues by reminding the reader that there are two quite different PCM standards. In addition, the author next concentrates on the network design of the PSTN, how it is structured and why. He also introduces the essential aspects for the design of long-distance links. Freeman next continues with information coding or how you can express your alphabet and numeric symbols electrically without ambiguity. Next, the author confines the reader to various data networks that may be employed in government and industry. He then covers two types of WANs: TCP/IP protocol family; and, frame relay and some of its variants. Freeman then provides the reader with a clear understanding of how a TV works, as well as, describe how television is transmitted and distributed over long distances. Then, the author describes conventional CATV, and the concept of supertrunks including HFC (hybrid fiber coax) systems. Next, he provides a brief overview of both SONET and SDH standards. Finally, Freeman finishes up by treating network management as a whole consisting of its multimedia parts: voice, image, and data, which includes facsimile, telemetry, and CAD/CAM.
With the preceding in mind, the author has done an excellent job crafting the book with the newcomer in mind. At the end of the day, you'll know whether you'll be gong back to basics or advance to the future of telecommunications.
