ABSTRACT:
A switching system for switching communication information between "M" incoming highways and "N" outgoing highways by using fixed-length cells, each having a header section and a data section and according to information contained in the header section (where "M" and "N" are integers), comprising: a demultiplexing unit for demultiplexing each incoming highway into a plurality of first output links; a switch unit, having the first output links of the demultiplexing unit as first input links and a plurality of second output links, for switching communication information between the first input links and the second output links; and a multiplexing unit, having "N" groups of input links, each group being formed by grouping a specified number of second output links, for multiplexing the cells on the second output links of each group and outputting them through one of third output links to a corresponding outgoing highway.
