Abstract
A switching apparatus for a switched network of the asynchronous transfer mode includes a path inspection control device connected to an input interface board, a switching network, and an output interface board. Cells for path inspection are supplied parallel to the input interface board; routing information is supplied to the switching network; the transmissions of the cells for path inspection are simultaneously switched accordingly; the cells for path inspection are delivered in parallel formation from the output interface board; the cells for path inspection delivered from the output interface board are compared with predetermined comparison data, and the routing information and the cells for path inspection or the comparison data are changed in synchronization with predetermined time signals.
