IPC: H04J3/00
Filed: 1979-06-20
Abstract: The present invention relates to a communications transmission system wherein there is superposed, on the conventional analog telecommunication network, a digital network whose digital local exchanges are connected with digital subscriber stations. Both networks are interconnected between the analog and digital local exchanges by way of analog/digital converters and digital/analog converters. In each digital subscriber station, a data transmission is possible simultaneously with voice transmission due to an automatic sub-channel formation by means of a multiplexer and a demultiplexer. An arrangement is provided for data clock pulse recognition to determine at which bit rate the respective data terminal operates, and causes a suitable sub-channel for the data to be arranged with a bit rate which is obtained from the voice channel.
