The invention provides a communication management device and a communication system, wherein the communication management device (5) connected with the server device (3) and the communication management device (6) connected with the terminal device (4) are connected to the transmission line (a). The transmission line (7) is connected to a power supply () for supplying power to the communication management device (5,6). In the case of a transmission destination connected to a communication management device (6) from a communication signal received by a transmission line (7), the communication management device (6) communicates with the terminal device (4) via a transmission line. In addition, in the absence of communication with the terminal device (4), the communication management device (6) operates in a reception standby mode for reducing power consumption.
