Abstract

A digital communications system efficiently transports communications data in ATM format from a plurality of information providers to a plurality of users, maximizing transport of the supply of ATM streams to distribution paths in a network. A video tone dial network arrangement synchronizes the timing among various VIP source multiplexers and super trunk transmitters. ATM streams are transported through an ATM backbone network and a local loop distribution network. A serving node, or host digital terminal, of the local loop distribution network, supplies the bit stream carrying ATM cells for a video program to the user terminal and provides information necessary to permit the terminal to decode the data from the ATM cells carrying the program information.
