Voice and Telephony Over ATM for Multimedia Network using Shared VCI Cell

Abstract

This paper presents new multimedia Asynchronous Transfer Mode (ATM) networks which are capable of transmitting voice data efficiently and serving smooth evolution from the existing narrowband voice networks. Fully ATMized networks are characterized by having both rerouting function and switching function. The rerouting nodes multiplex plural calls going through the same route into one ATM cell, namely shared virtual channel identifier (VCI) cell. The shared VCI cell includes fellow cells which contain call data and its VCI. The rerouting node is integrated into a single chip by using CMOS technology. The multimedia ATM networks can be readily implemented by attaching the rerouting nodes to the standard ATM switches.
