Abstract
An ADM apparatus includes a first synchronism section for detecting synchronism when a reception frame received from a reception port is a first frame, a fault information detection section for detecting whether or not fault information is set in a first predetermined region of an overhead of the first frame and outputting a signal representative of whether or not the fault information is set, a second synchronism section for detecting synchronism when the reception frame is a second frame, a third synchronism section for detecting synchronism when the reception frame is a third frame accommodated in the second frame, and an inhibit section for invalidating the output signal of the fault information detection section if, when the synchronism is detected by the first and second synchronism sections, synchronism is detected with regard to the preceding frame by the second synchronism section.
