  • Patent number: 11984925
    Abstract: A transmission apparatus includes a first communication unit, a second communication unit, a detection unit, a control unit, and a selection unit. The first communication unit uses a first path for communication, when electric power is supplied. The second communication unit uses a second path for communication, when electric power is supplied. The detection unit detects a fault predictive sign. The control unit supplies no electric power to the second communication unit when the detection unit does not detect the fault predictive sign. The control unit starts supplying electric power to the second communication unit and performs normality confirmation of the second path when the detection unit detects the fault predictive sign, before switching from the first path to the second path.
