Abstract

PURPOSE: To realize large capacity without being affected by a reply response time of a control system by suppressing the increase in the circuit scale in the extension form in which the configuration resulting from eliminating a control section from an ATM cross connect device of common buffer configuration with less circuit scale is used as a basic module and plural basic modules are connected with respect to the device where the line is set by the replacement of cells multiplexed in the ATM (asynchronous transfer mode).
CONSTITUTION: The device is provided with plural input ports 11, output ports 15, plural basic modules 12 having a buffer 43 in common to the ports, a spatial switch network 13 fetching a cell of the output port 15 of each basic module 12 and outputting the cell to a prescribed output port through routing, and a control means controlling a cell 40 sent from each basic module 12 to the spatial switch network 13 to avoid cell contention in the spatial switch network 13.
