A communications relay system for establishing data communications between an external device and a plurality of communication devices. In the system, the plurality of communication devices and a relay device are connected to a communication path to form a communication network. The relay device is operable to relay communications between the external device and the plurality of communication devices when being connected to and powered by the external device. With this configuration, the system is capable of reducing power consumption in the relay device to thereby reduce power consumption over the communication network.
