Abstract:
1. A transmission apparatus comprising: a receiving unit that receives a signal from an external source; an electrical power supplying unit that supplies electrical power; a first interface board that includes a first signal processing unit that performs a predetermined process on the signal received by the receiving unit; a second interface board that includes a second signal processing unit that performs the predetermined process on the signal received by the receiving unit; a switching control unit that selects the first interface board when no failure occurs in both the first interface board and the second interface board and that performs switching to select the second interface board when a failure occurs in the first interface board; an electrical power supply control unit that, in a case in which no failure occurs in both the first interface board and the second interface board and when the first interface board does not satisfy a predetermined degradation condition, supplies electrical power from the electrical power supplying unit to the first interface board and prohibits supply to the second interface board and that, in a case in which no failure occurs in both the first interface board and the second interface board and when the first interface board does satisfy the predetermined degradation condition, supplies electrical power from the electrical power supplying unit to both the first interface board and the second interface board; and a transmitting unit that transmits a signal processed by one of the first interface board and the second interface board that is selected by the switching control unit.
