Communications system for digital data transmission has a communications network based on an asynchronous transfer mode with communications nodes as access to the network

摘要

Each communications node (KNK1, KNK2 ...) has a switching/conferencing unit (SWAC1) that forwards signals from first (TA1) to second (TA2) terminal adapters and, if required, can also carry out a conferencing facility between more than two terminal adapters. A network interface manager (NIM) serves as an interface between nodes and a communications network. An independent claim is also included for a method for operating a communications system.
