<p>PURPOSE:To accommodate outgoing lines with various transmission line speeds by providing a multiplexer or a demultiplexer to an output link. CONSTITUTION:An ATM switch 1 comprising a multiplexer 12, a common buffer memory 11, a demultiplexer 13, and a buffer memory control circuit 10 managing a buffer for each cell type is provided with a band control table 104 commanding the kind of a cell read from a buffer. Thus, the cell kind is managed corresponding to an outgoing line and the cell type is commanded in a read timing corresponding to each outgoing line in the band control table, and various outgoing lines with different transmission speeds are accommodated by providing a multiplexer or a demultiplexer to an output link of the switch.</p> |
