For this reason, information on failures that occur during test maintenance is displayed in the same way as actual failures. Usually, higher-level monitoring equipment and centralized monitoring stations are
Because the transmission equipment that undergoes maintenance testing is located far away from the local station, there was a problem in which the monitors mistakenly assumed that the equipment was malfunctioning and took recovery measures. .

When performing a maintenance test on a specific transmission device (for example, transmission device 3-2) that belongs to the frame, first send the command CD indicating maintenance test in progress and the address AD indicating transmission device 3-2 from the maintenance terminal 4 to the rack. The information is input to the device information aggregation device 31. This CPU 32 receives the input command CD and address A.
D determines that a maintenance test is to be performed on the transmission device 3-2, sends this maintenance test notification information to the upper monitoring device, and stores the address CD in the memory 33. Due to the start of maintenance test work, transmission equipment to be maintained 3-2
stops normal operation due to a power cut, etc., and the fault information aggregation device 3 collects the fault information with address AD and code S indicating the fault type.
Send to 1. When the fault information aggregation device 31 receives this fault information, it compares the received address CD with the address CD it has stored, and if they match, the fault information is pseudo fault information resulting from maintenance test work. If so, the information is rejected and not forwarded to the higher-level monitoring device. If an actual failure occurs in other transmission equipment within the same rack that is not subject to test maintenance, the address comparison results do not match, so the failure information is not masked and is normally sent to the higher-level equipment. .
