Abstract
Disclosed is a transmission apparatus in which a plurality of elements implement virtually one apparatus. Each element includes at least one main signal package and a monitor control package that is connected to the main signal package via an intra-apparatus busand connected to another monitor control package via an inter-apparatus communication bus. The monitor control package in one element, on occurrence of a malfunction in the main signal package being monitored, collects an alert from the main signal package being monitored, and transmits an alert masking control signal, using the inter-apparatus bus, to the monitor control package of another element to which belong the main signal package of a masking target. The main signal package of the masking target suppresses alerting of a second-order malfunction in case of detection of the second-order malfunction on receipt of the alert masking control signal.
