Abstract
An ATM switch supplies an ATM terminal with a display command for causing a display apparatus provided in an ATM communication apparatus or an ATM transmission route to provide a display. The communication apparatuses and the ATM transmission route receiving the display command cause respective light-emitting bodies to emit light. Thus, the transmission route on which the display command is transmitted is visualized by illuminated display. The status of failure is readily determined based on the status of illuminated display.
