Informationen zum Autor David J. Wright University of Ottawa! Canada Klappentext One of the hottest topics in the telecommuncations industry today is the migration of voice traffic from the circuit switched Telco networks to packet switched networks such as IP! ATM! Frame Relay and access technologies such as DSL (Digital Subscriber Line) and Packet Cable. The sheer volume of voice traffic! together with the efficiencies of packet transport and the opportunity to offer new features on voice calls! has made internetworking! between circuit and packet transport! vital while this migration is in progress.* Presents a concise treatment of a complex subject providing up-to-date coverage of all relevant packet voice technologies and an evaluation of how they compare* Explains how and why to transport voice over packet networks* Includes MEGACO: Media Gateway Control Protocol! Voice over Packet Cable and Voice over DSL* Enables the reader to obtain information rapidly by featuring numerous bulleted lists and extensive diagramsVoice over Packet Networks is comprehensive and compact and will be welcomed by both engineers and planners in the telecommunications industry! as well as graduate and senior undergraduate students on telecommunication courses. Zusammenfassung Dieser Band vergleicht alle Paket-Übertragungstechnologien für Sprachdaten - von ATM über IP bis zu Frame Relay.. So lernen Sie! im Hinblick auf den Einsatzzweck zwischen den angebotenen Alternativen auszuwählen! Vermittelt werden Kenntnisse! die zum Aufbau einschlägiger Netzwerke und zur Entscheidung für die am besten geeignete Technologie notwendig sind. Beim Verständnis des Stoffes helfen Ihnen zahlreiche übersichtliche Diagramme und Stichwortlisten.
