Data communication is the movement of encoded data by electronic means. It is the fastest growing segment of the telecommunications industry and is involved in almost every facet of life today. Written by bestselling telecommunications expert Roger Freeman, this updated edition provides a complete overview of data communications and a comprehensive guide to its practical aspects. Both a tutorial and a practical reference for the design and operation of data networks, this is the most comprehensive and detailed book available on data communications. Content: Chapter 1 The Enterprise Network Environment (pages 1–11): Chapter 2 The OSI Model and the Data?Link Layer (pages 13–40): Chapter 3 High?Level Data?Link Control (HDLC) Typical Data?Link Layer Protocol (pages 41–55): Chapter 4 Data Network Operations (pages 57–71): Chapter 5 Data Transmission I (pages 73–88): Chapter 6 Data Transmission II (pages 89–119): Chapter 7 The Telecommunications Network as a Vehicle for Data Transport (pages 121–153): Chapter 8 The Transmission of Data over the Analog Voice Channel (pages 155–201): Chapter 9 Data Communications in the Office Environment, Part 1 (pages 203–288): Chapter 10 Data Communications in the Office Environment, Part 2 (pages 289–361): Chapter 11 Wide Area Networks (WANs) (pages 363–432): Chapter 12 Frame Relay (pages 433–481): Chapter 13 Integrated Services Digital Networks (ISDNs) (pages 483–525): Chapter 14 Building and Campus Wiring and Cabling for Data Communications (pages 527–549): Chapter 15 Broadband Data Transport Techniques (pages 551–600): Chapter 16 Broadband ISDN (B?ISDN) and the Asynchronous Transfer Mode (ATM) (pages 601–679): Chapter 17 Last?Mile Data Distribution Systems (pages 681–725): Chapter 18 Network Management for Enterprise Networks (pages 727–756): Complete coverage of data communication network design for IT specialists Effective data communication is vital to modern businesses. Whether sending data over short or long distances, speed, simplicity, and efficiency are of paramount importance. This new, fully updated Second Edition of Practical Data Communications is an indispensable guide for IT managers, computer scientists, system engineers, or any professional who must design or maintain data communication networks. Professionals will find it useful as a reference for precise terminology, applications, and practices in the field. The book stresses explanation and concepts rather than theory, with current practice as the underlying theme. Roger Freeman emphasizes generalized data networks and their protocols, rather than limiting the scope of the work by concentrating on proprietary systems. While most resources in the field forgo description of the underlying digital network, discussion of PSTN as well as SONET and SDH is included here in order to allow readers to better take advantage of services available from the public network. Other sections feature discussions of:*Fiber-optic transmission*ATM and IP*Frame Relay*LANs and WANs*Last mile broadband*Gigabit EthernetWritten to facilitate an understanding of data communications that emphasizes practical applications rather than theory, Practical Data Communications, Second Edition serves as an excellent tutorial for students or professionals with only basic understanding of the subject "This new, fully updated Second Edition of Practical Data Communications is an indispensable guide for IT managers, computer scientists, system engineers, or any professional who must design or maintain data communication networks.

Emphasizing practical applications rather than theory, this comprehensive tutorial and reference explores this fast growing segment of the telecommunications field with simple explanations, detailed drawings, and step-by-step discussions of each topic.

This book serves the practitioner. Its wide discussion of data network enhancements and design is built upon a thorough introduction of generic and specific data networks, focusing at length on transmission limitations, protocols and how they work, and questions of standards and related topics. The book covers local area networks (LANs) based on IEEE and ANSI standards, and wide area networks (WANs) built around TCP/IP, SNA, and OSI related protocols. It also covers VSAT (very small aperture terminal) satellite networks for data connectivity, and frame relay and SMDS for the interconnection of LANs over long distances. The reader will share the benefits of the author's extensive experience, detailing actual implementation methods for enterprise networks, considering particular corporate and government requirements, describing wiring concepts and specific models, and providing comparisons between different systems in terms of performance and complexity. Throughout, data communication is incorporated into the bigger picture of telecommunications, including the public switched digital network (PSDN), questions of high-capacity transmission media such as fiber optics, wire pair, and microwave and satellite communications. There is emphasis on the trend toward the integration of data, voice, and image into a single telecommunication system - popularly termed multimedia communications. Data communication is the movement of encoded data by electronic means. This edition provides an overview of data communications, and a guide to its practical aspects. It also serves as a tutorial and a reference for the design and operation of data networks. An enterprise network is a highway that transports data from one user station to another.
