ABSTRACT:
An ATM switching system has a receiving unit for receiving an ATM cell, reassembling it into a frame and temporarily storing a buffer memory with this frame. When the receiving unit receives the cell, there is discriminated whether the cell is a continuous in-receipt cell or a last cell. A cell-to-cell receiving time or a receiving time between a head cell and the last cell is monitored. When this receiving time exceeds a set time, a determination is that the cell loss is detected. Invalid holding of a buffer memory is restrained by releasing the buffer memory.
