44759-9 Synchronous networks for optimum performance Today's high-speed network applications depend on the latest in high speed, synchronous transport technology for reliable operations. SONET and T1: Architectures for Digital Transport Networks gives you the big picture on SONET, the second-generation digital carrier system, placing it in the context of the widely used first-generation system, T1. This rich resource offers detailed information on the how's and why's of managing a SONET system. SONET and T1: Architectures for Digital Transport Networks explains how to structure and maintain a high-performance network, using real-life examples of systems currently in use in a variety of business, industrial, and institutional settings. In addition, this book shows how to use SONET to interface with a variety of local and international networks, and to minimize data loss when communicating with older systems.Key chapters explore: *The basics of digital carrier systems *Timing and synchronization in digital networks *Payload mapping and management *Topologies and configurations, including add-drop and cross-connect *Operations, administration, and maintenance of digital networks *Case studies of existing SONET systems Appendices provide valuable background material on the structure, function, and performance of fiber optics, and a review of ATM technology. Filled with practical and specific information, SONET and T1: Architectures for Digital Transport Networks provides a thorough introduction to the latest in digital network technology.
