<p>Disclosed is a data relay device which is mainly used on the domestic side, and which exhibits improved conservation of electrical power compared to conventional data relay devices. The disclosed data relay device (R) (included in an domestic-side device, for example) for carrying out data transfer from one port to another port, reduces the electrical power consumption by implementing a control which reduces the receiving function of a receiving unit (1) in a port (port 2), on the condition that an instruction for control is received from a device at the other end of communication (for example, a company-side device) which is connected to the port, and/or the device itself notifies the other end of communication of information relating to control. When specified return conditions have been reached (for example, a specified time period has passed or a specified point in time is reached), the data relay device returns the receiving function. When the above occurs, the knowledge that the receiving function is being reduced can be shared with the other end of communication, and thus the other end of communication can determine not to carry out data transfer to the data relay device (R) while receiving function is being reduced.</p> |
