摘要： A disclosed optical add/drop multiplexing device demultiplexes a first signal into multiple signals according to wavelengths, drops one or more of the demultiplexed signals to a transponder, adds one or more signals output from the transponder, multiplexes these signals into a second signal, and outputs it. The device includes an injecting unit for injecting one of measurement signals, each of whose wavelength corresponds to that of a different demultiplexed signal, into a core of a multicore cable within the device, the core being used to transmit the different demultiplexed signal having the corresponding wavelength; a preventing unit for preventing the one measurement signal from emanating; a measuring unit for measuring, for each wavelength, levels of the one measurement signal before and after the corresponding core; a calculating unit for calculating loss of the corresponding core, based on the measured levels; and an informing unit for reporting the calculated loss.

摘要： A component device (such as an input circuit interface device, a cell multiplexing device, a cell switching device, a cell demultiplexing device or output circuit interface device) in an ATM exchange counts an inflow cell number, a passage cell number and discard cell number. The firmware of the device subtract the passage cell number and the discard cell number from the inflow cell number to find a difference at predetermined interval. If the difference is larger than the predetermined threshold value, the firmware informs the software of fault warning.
