Supplying and branching off audio signals at network junction

摘要

A control circuit (5) with a coupled (de)multiplexer converts a standard multiplex signal, fed to the demultiplexer of a first information transmission system, into a standard multiplex signal of a second information transmission system. At the network junction the audio signals from several transmission systems are supplied to a single collector multiplexer (4A), each via a network access demultiplexer (4B,C,D). The collector multiplexer collects the standard signals, synchronizes and converts them into a single standard multiplex signal. An Independent claim is included for a supplying and branching off device.
