Abstract
A cell count identifier inserting portion for inserting a cell count identifier into the header portion of a cell is provided at a predetermined position within an exchange and a plurality of cell counting portions for counting a cell into which a cell count identifier is inserted are provided on the downstream side of the cell count identifier inserting portion. A cell loss detecting portion compares the number of cells into which the cell count identifier is inserted with the number of cells counted by each of the cell counting portions, detects cell loss on the basis of the result of the comparisons and specifies the section in which cell loss is caused, if the cell loss is detected.
