A cell multiplexing apparatus including call monitors and multiplexers. The call monitors monitor a plurality of channels for their call setting status and select at least two channels for which the same cell may be assembled, i.e., for which the destination of the calls is the same. The multiplexers receive audio information or information already assembled in asynchronous transfer mode (ATM) cells from the channels selected by the call monitors, and disassemble and multiplex the received information for assembly into the payload of a new ATM cell.

Cell multiplexing apparatus handling multiple items of information

A delay distortion suppressing system is for use in an asynchronous transfer mode communication system which includes at least a transmitting end and a receiving end which are connected via transmission paths. The delay distortion suppressing system includes a first part provided in the transmitting end for transmitting information in the form of cells in an asynchronous transfer mode, a second part provided in the receiving end for delaying each cell which is received via a transmission path by a predetermined delay time relative to a reference point, a third part provided in the receiving end for varying the reference point depending on an arrival time of the cell which is received at the receiving end via the transmission path, so that a delay distortion of the cells is suppressed, and a fourth part including a decoding part for decoding the cells output from the second part.
