Abstract
A multiplexer and a demultiplexer time-division multiplex and demultiplex binary data in the form of cells having a fixed number of bits. For example, to time-division multiplex cells comprising 424 bits the original bit rate of a block of 16 bits of a cell is multiplied by four, each cell being divided into a series of 27 blocks. The blocks constituting each cell are concatenated after their bit rate has been multiplied. Similarly, the demultiplexer divides the bit rate by dividing each cell into blocks, separating consecutive blocks by a gap and dividing the bit rate successively in each block. The multiplexer and demultiplexer have applications in time-division multiplex telecommunication networks.
