<p>PURPOSE:To realize a high-speed cell routing. CONSTITUTION:Incoming subscriber addresses stored in the information field of BOM cell is latched to a DA latch circuit 13. The incoming subscriber address DA is converted into address information RDA with less number of bits by referring to DA-RDA conversion table TB. A selector 15 writes the address information RDA as information specifying incoming subscriber on the header of the BOM cell stored in a buffer 14. In routing cells in the message handler, the address information RDA written in the cell header is processing by the hardware or the like to determine the outgoing path of the cell.</p> |
