This book provides a broad introduction to all aspects of modern telecommunications networks, covering the principles of operation of the technology and the way that networks using this technology are structured. The main focus is on those technologies in use today and the next generation networks (NGN) and how they will be implemented.

Part of Delmar Learning's new National Center for Telecommunications Technologies series, this book begins with the history of the public switched telephone network (PSTN). Descriptions of public and private telecommunications networks, plus a basic electronics refresher, are provided. Subsequent chapters offer a complete overview of existing network infrastructure, with discussion of analog and digital signals concepts, frequency spectra, plus modulating and multiplexing techniques. System hardware is also introduced, including transmission and reception technology, switching systems and more.

This book responds to the growing need to secure critical infrastructure by creating a starting place for new researchers in secure telecommunications networks. It is the first book to discuss securing current and next generation telecommunications networks by the security community. The book not only discusses emerging threats and systems vulnerability, but also presents the open questions posed by network evolution and defense mechanisms. It is designed for professionals and researchers in telecommunications. The book is also recommended as a secondary text for graduate-level students in computer science and electrical engineering.

Network synchronization deals with the distribution of time and frequency across a network of clocks often spread over a wide geographical area. The goal is to align (i.e. synchronize) the time and frequency scales of all clocks, by using the communication capacity of their interconnecting links. Network synchronization plays a central role in digital telecommunications as it determines the quality of most services offered by the network operator. However, the importance of network synchronization is often underestimated and how to solve quality-of-service degradation caused by synchronization difficulties can become problematical to all but a synchronization engineer. * Systematically covers a wide spectrum of both theoretical and practical topics * Features a clear and profound description of synchronous and asynchronous digital multiplexing (PDH, SDH), jitter and timing aspects of SDH networks * Expounds synchronization network principles and implementation issues, clock modelling, time and frequency measurement * Presents recent advances in telecommunications clock characterization and measurement If you are a system engineer, researcher, designer or postgraduate student searching for both the basics and an insight into more advanced areas currently under discussion then you will find Synchronization of Digital Telecommunications Networks an enlightening read. It will also prove to be a valuable sourcebook for senior undergraduates and technical personnel in telecommunications companies.

Dynamic routing techniques are the key to growth in every kind of telecommunications network. Here at last is the definitive guide that shows how to analyze, design, manage, and operate dynamic networks - written by one of the key originators of the technology. Based on actual implementation, this in-depth manual provides all the tools needed by network engineers and planners involved with any aspect of dynamic networks. The author's practical, A-to-Z treatment of the subject will also prove invaluable to telecommunications software designers, researchers, and students.

Whether you are an executive or sales manager in a networking company, a data communications engineer, or a telecommunications professional, you must have a thorough working knowledge of the ever growing and interrelated array of telecom and data communications technologies. From protocols and operation of the Internet (IP, TCP, HTTP, ...) and its access systems such as ADSL, and GSM... to the basics of transmission and switching, this newly revised resource delivers an up-to-date introduction to a broad range of networking technologies, clearly explaining the networking essentials you need to know to be a successful networking professional. Moreover, the book explores the future developments in optical, wireless and digital broadcast communications.

Guidance to help you grasp even the most complex network structures and signaling protocols The Second Edition of Signaling in Telecommunication Networks has been thoroughly updated, offering new chapters and sections that cover the most recent developments in signaling systems and procedures. This acclaimed book covers subscriber and network signaling in both fixed and mobile networks. Coverage begins with an introduction to circuit-switched telephone networks, including an examination of trunks, exchanges, access systems, transmission systems, and other basic components. Next, the authors introduce signaling concepts, beginning with older Channel Associated Signaling (CAS) systems and progressing to today's Common Channel Signaling (CCS) systems. The book then examines packet networks and their use in transmitting voice (VoIP), TCP/IP protocols, VoIP signaling protocols, and ATM protocols. Throughout the book, the authors emphasize functionality, particularly the roles of individual protocols and how they fit in network architectures, helping readers grasp even the most complex network structures and signaling protocols. Highlights of the Second Edition include: Coverage of the latest developments and topics, including new chapters on access networks, intelligent network application part, signaling for voice communication in packet networks, and ATM signaling Drawings and tables that help readers understand and visualize complex systems Comprehensive, updated references for further study Examples to help readers make the bridge from theory to application With the continued growth and expansion of the telecommunications industry, the Second Edition is essential reading for telecommunications students as well as anyone involved in this dynamic industry needing a solid understanding of the different signaling systems and how they work. Moreover, the book helps readers wade through the voluminous and complex technical standards by providing the essential structure, terminology, and functionality needed to understand them.

Written by one of the most respected members in the telecommunications industry, this book covers the field of telecommunications and the rapidly evolving network technologies of the future. Both packet switching and circuit switching are covered in detail from qualitative discussion to performance analysis.

How does a telecommunications company function when its right hand often doesn't know what its left hand is doing? How do rapidly expanding, interdisciplinary organizations hold together and perform their knowledge work? In this book, Clay Spinuzzi draws on two warring theories of work activity - activity theory and actor-network theory - to examine the networks of activity that make a telecommunications company work and thrive. In doing so, Spinuzzi calls a truce between the two theories, bringing them to the negotiating table to parley about work. Specifically, about net work: the coordinative work that connects, coordinates, and stabilizes polycontextual work activities. To develop this uneasy dialogue, Spinuzzi examines the texts, trades, and technologies at play at Telecorp, both historically and empirically. Drawing on both theories, Spinuzzi provides new insights into how net work actually works and how our theories and research methods can be extended to better understand it.
