<p>PROBLEM TO BE SOLVED: To provide switching architecture for expanding the ability of a switchboard by utilizing the respective storage resources of a switching system. SOLUTION: A switching system 15 or 25 receives data cells from the set of (n) pieces of input ports, and according to the contents of a bit map value led into the cell at the entrance of a module, the cell is routed to output ports more than one. The module is provided with a shared buffer for storing the routed cell. Further, this system is provided with an additional mask mechanism having a mask register for changing the bit map value according to whether the concerned cell is to be moved to the output port or to be abandoned before that bit map value is used for controlling a routing process.</p> |
