optical zeitmultiplexer and optical zeitdemultiplexer

摘要

The invention relates to a multiplexer and a demultiplexer for time-division multiplexing and demultiplexing of binary data which are in the form of cells having a number of fixed bits. For example, for the time-division multiplexing of cells containing 424 bits, one embodiment includes in particular: - means (120) for multiplying by four the initial throughput of a block of 16 bits of a cell, each cell being partitioned into a sequence of 27 blocks; - means (121) for concatenating the blocks constituting each cell after their throughput has been multiplied. Similarly, a demultiplexer according to the invention includes means for dividing the throughput by partitioning each cell into blocks, separating the consecutive blocks by a gap, and then dividing the throughput successively in each block. Application to a synchronous time-division multiplexed telecommunications networks. IMAGE
