Equipment for digital multiplexing and demultiplexing of packets with different lengths.

摘要

The invention aims to facilitate the processing of packets, of the HDLC type, transported by pairs of outgoing and incoming channels (CE,CS) constituting digital subscriber lines having the same throughput for an ISDN network, by means of a single packet-processing unit (UTP). In the multiplexing equipment (EM), the incoming channels (CS) are time-division multiplexed in groups of bits, such as bytes, in a multiplex path (MUXE), then the bit groups of each packet are systematically written to a storage memory (3), and the packets are read in chronological order for serial transmission in a single digital path (VPS) connected to the unit (UTP). In this path having a throughput equal to or less than the multiplex path, scaled markers are inserted between the packets read. The demultiplexing equipment (ED) performs operations reciprocal to those mentioned above. <IMAGE>
