PROBLEM TO BE SOLVED: To reduce a manufacture cost and a maintenance/management cost by providing an input copy part provided with a means for imparting routing information to a duplicated cell and a switch part for connecting input/output channels in 1:1 correspondence. SOLUTION: In the input copy/header conversion tables 64-1-64-4 of the input copy parts 60-1-60-4, the routing information to a plurality of predetermined output channels 50-1-50-4 corresponding to the destination information of an arriving cell and the duplication number of the cell for performing distribution to the output channels 50-1-50-4 are recorded. In input copy/header conversion processing parts 61-1-61-4, the cell is duplicated corresponding to the input copy/header conversion tables 64-1-64-4 and the pertinent routing information is imparted to the cell duplicated corresponding to the input copy/header conversion tables 64-1-64-4. Then, the switch part 100 connects the input/output channels in the 1:1 correspondence corresponding to the routing information. |
