PREFACE

Telecommunications, Fourth Edition, has been upgraded to include more example problems, figures, tables, and a margin glossary, and covers the latest standards and emerging technologies developed in recent years. This book is intended to provide the reader with the technical aspects and background material on telecommunications, which is still one of the fastest-growing industries in the world. A broad range of topics is covered without the intricate details of mathematical derivations and proofs. Instead, fundamental principles are emphasized in a simplified yet comprehensive and practical manner. To achieve this, numerous sketches with detailed explanations are included throughout, all aimed at providing the reader with the practical knowledge needed by today's telecommunications engineer and technician. INTENDED AUDIENCE

This book is intended primarily for use as a college text in data communications or telecommunications. A fundamental background in mathematics, electronics, and digital circuits is a helpful requirement to using the text. This text is of great value to undergraduates and graduates seeking to extend or renew their discipline. Furthermore, the myriad tables, figures, example problems, and telecommunication standards make it an excellent reference for faculty, students, and practitioners. Instructors will find the material clear, concise, and written with sufficient depth. Experiments can be easily implemented to reinforce example problems presented in the text. This book also serves as an excellent reference guide for those in the industry who want to keep abreast with the subject matter. For those interested in achieving some degree of computer literacy, a wealth of technical terms and acronyms are defined and discussed throughout. They are also included in an extensive glossary at the end of the book. ORGANIZATION OF THE TEXT

The chapters in this text are arranged in an order that has been successfully presented in a series of telecommunications and data communications courses over the years. It is by no means the suggested order in which the material should be taught; some chapters may be covered independently of each other. For example, some instructors may choose to cover Chapter 13, Modems, prior to Chapter 12, The Telephone Network. The same may be true of Chapter 18, Fiber Optics, which, like many chapters, is a subject in itself. Chapters are organized as follows:

Chapter 1, Introduction: An overview of telecommunications is presented in this chapter. Distinctions between analog and digital signals as well as data communications versus telecommunications are made. The 1996 Telecommunications Reform Act is also covered.

Chapter 2, Noise: Noise is an inherent problem in any communication system. This chapter introduces the various types of noise, their characteristics, and their effects on the telecommunication system. Signal-to-noise ratio, noise figure, noise factor, relative versus absolute power gain, and decibel are also introduced. Several example problems are given.

Chapter 3, Amplitude Modulation: The theory of AM is presented in this chapter. The frequency components of the AM waveform and their respective amplitudes, along with the single-sideband (SSB) and its derivation from the AM wave, are examined. Modulation index, power, and signal generation are also discussed.

Chapter 4, Frequency Modulation: The theory of FM is presented in this chapter. Bessel functions are defined and examined in terms of the frequency and amplitude components of the FM waveform. Modulation index, noise, and other important parameters associated with FM are also discussed.

Chapter 5, Pulse Modulation: Pulse modulation is used in most telecommunication systems. This chapter presents an introductory analysis and comparison of PAM, PCM, PWM, PPM, and Delta modulation. The Phase-Locked Loop (PLL) technology and encoding techniques, such as Miller, Manchester, Differential Manchester, NRZI, NRA, BBZS, and more, are introduced.

Chapter 6, Transmission Codes and Encoding Techniques: Several codes commonly used in communication systems are examined in this chapter. Binary, octal, decimal, and hexadecimal number systems have been added to this chapter. An introduction to bar code technology is also given with emphasis on UPC, Code 39, and POSTNET. Chapter 7, Terminals: In this chapter, various types of terminals and their features are discussed, with emphasis on the ASCII terminal. Examples of escape sequences and use of control characters, as well as the network computer (NC) terminal, are presented. Coverage of the PC Card (PCM/CIA) and the Small Computer Systems Interface (SCSI) has been added.

Chapter 8, Serial Interfaces: This chapter begins by distinguishing between synchronous and asynchronous serial transmission. Serial interfaces, RS-232 and RS-449, and its supporting standards—RS-422-A, RS-423-A, RS-485, V.35, and V.530-are examined in depth.

Chapter 9, The DART: An extensive study of the DART is given in this chapter. Transmitted and received serial characters are examined. The conversion process of these characters from serial to parallel form and vice versa are examined.

Chapter 10, The UART Interface: This chapter is devoted to interfacing the 8085A microprocessor to the 8251A USART. An asynchronous 4800-baud program is discussed, along with an interface schematic diagram. An introduction to the high-speed 16550 UART is also presented.

Chapter 11, The Telephone Set and Subscriber Loop Interface: This chapter provides a detailed look at touch-tone and rotary dial telephones and their specifications along with the tip and ring subscriber loop interface specifications. New in this chapter is the wire color coding used to identify subscriber loop wire pairs.

Chapter 12, The Telephone Network: This chapter examines the telephone network's history and how it has evolved into the world's most sophisticated network of computers. The central office and its numerous functions, characteristics, and system components are discussed. The T-carrier signaling format and multiplexing techniques cued in the telephone network are also covered.

Chapter 13, Modems: The Bell family of modems and their characteristics, as well ac the latest ITU-TS (formerly CCITT) modem recommendations, are discussed. Features such as data compression, scrambling and descrambling, loopback tests, and various modulation techniques are presented. An introduction to ADSL and cable modem is also presented.

Chapter 14, Protocols: Synchronous serial link protocols are discussed in this chapter. These include BISYNC, SDLC, and HDLG In addition, various standards organizations that have given rise to the development of the ISO/OSI seven-layer model are described.

Chapter 15, Local Area Networks: Common LAN topologies, access control methods, and internetworking devices such as hubs, bridges, switches, and routers are introduced in this chapter. Emphasis is placed on the Ethernet and Token Ring protocols. A detailed presentation of LAN cabling and connector media for the 10BaseT, 10Base2, 10Base5, 100baseT, and 100BaseFL specifications are also discussed.

Chapter 16, The Internet and Emerging Technologies: An overview of the Internet and the World Wide Web is presented, along with TCP/IP (the Internet protocol suite). A detailed look at the ISDN, ATM, and SONET standards is given. New in this chapter is an introduction to the XDSL family.

Chapter 17, Error Detection, Correction, and Control: This chapter presents an in-depth look at some of the common error-detection and error-correction mechanisms used in telecommunication systems. Examples of computing the CRC block check character are given. A Hamming code is developed and used to correct single-bit errors.

Chapter 18, Fiber Optics: Fiber optics has become an integral segment of the telecommunications industry. This chapter provides a detailed look at the various grades of fiber and their respective characteristics. The theory of light, including Snell's law and the concept of total internal reflection, is examined. Multiplexing techniques of WDM and DWDM are introduced.

Chapter 19, Wireless Communications: This chapter presents an overview of the wireless industry, starting from the first-generation analog mobile and cellular telephone systems to the latest generation of digital cellular telephones, cordless telephones, wireless LANs, and personal communication services (PCS).
