In the figure, a data relay device 2 provided between the terminal 1 and the exchange 3 is shown. The data relay device 2 receives a power receiving circuit 21 that receives power from the terminal 1, a power receiving monitoring circuit 22 that monitors the power receiving level of the power receiving circuit 21, a power receiving level from the power receiving monitoring circuit 22 and communication data from the terminal 1, and receives data. From the data conversion circuit 23 that multiplexes the power reception level to the converted data and sends it to the exchange 3, the power reception circuit 24 that receives power from the exchange 3, the power reception monitoring circuit 25 that monitors the power reception level of the power reception circuit 24, and the power reception monitoring circuit 25 Power receiving level and switch 3
It is constituted by a data conversion circuit 26 which receives the communication data from the terminal 1 and multiplexes the power-reception level with the data converted to send it to the terminal 1. The power received by the power receiving circuit 21 is given to the power receiving monitoring circuit 25 and the data converting circuit 26, and the power received by the power receiving circuit 24 is given to the power receiving monitoring circuit 22 and the data converting circuit 23.
