Today, ATM networks, SONET lines, frame relay networks, X.25 facilities, ISDN circuits, and conventional telephony lines coexist in a complex tapestry of networks. Wide Area High Speed Networks clearly explains each of these technologies in detail, describes how they interoperate, and shows how voice and data networks are merging. Wide Area High Speed Networks is an authoritative resource that enables networking designers and implementors to thoroughly understand each technology and determine when and where to use each type of component in their networks. A comprehensive guide to the latest in wide area technologies, this book covers the new high-speed telecommunications SONET/SDH hierarchy, how to use and manage ATM, SONET and ISDN transmission technologies, frame relay performance and service issues, converged voice/data networks, and detailed discussion of traditional telecommunications and data networks.
