ABSTRACT:
In a multiplex communication system, D-channel control signals are stored in respective buffers and data quantity of the control signals is detected. The buffers are read according to the detected data quantity and a format control signal is produced corresponding to the detected data quantity. Multiple B-channel information-bearing signals and D-channel control signals read out of the buffers are multiplexed into one of a set of different multiframe formats according to the format control signal, producing therefrom a multiplex signal which is transmitted through a communication channel. At a receive site, the multiplex signal is decomposed according to the format control signal contained therein.
