Abstract: A power supply controller includes a first port, a second port, and a controller. The first port is connected to a power supply device. The second port is connected to a first relay node device via a wired path. The controller performs control to supply power received from the power supply device from the second port to the first relay node device. The controller performs control to generate a power-on instruction frame for instructing the first relay node device started by receiving power supply to start power supply from a port included in the first relay node device to a second relay node device connected to the first relay node device via a wired path. The controller performs control to transmit the generated power-on instruction frame from the second port.

Abstract: A node equipment includes a receiver, a processor, a memory and a transmitter. The node equipment is relayed by a plurality of relay devices with a server. The receiver receives a frame from adjacent node equipment. The processor generates a wait number by incrementing a number of hops for each of the relay devices, when the number of hops to the adjacent node equipment is reported with a synchronization request, the number of hops being generated by designating each of the plurality of relay devices as a starting point. The memory stores the wait number in association with an identifier of the relay device. The transmitter transmits a data frame in which the server is designated as an address. The processor outputs to the transmitter a data frame in which a relay device having a relatively small wait number stored in the memory is designated as a relay destination.

Abstract: A wireless communication terminal including a wireless communication unit for receiving and transmitting voice signals between terminals connected through a voice channel and a data channel, a signal input/output unit for inputting and outputting voice signals for voice communication and a mixing unit, interposed between the wireless communication unit and signal input/output unit, for performing mixing operations to create a first mixed signal to be output to said signal input/output unit and second mixed signals each to be transmitted to the corresponding terminal. The wireless communication terminal is preferably used for wireless voice communication performed by three or more terminals without being interposed by a center apparatus (such as a server) or a repeater. Further, signal-receiving/transmitting is set for each wireless communication terminal whereupon convenience can be improved.

Abstract: A back wiring board which connects a printed board package to testers and an aggregated device of back wiring boards. A receiving portion receives a test demand signal from an external controller, a selector selects and connects one of the testers connected to adapter connectors for the connection to the printed board package based on the test demand signal. Group connectors connect a plurality of the back wiring boards to form a board group. The selector selects and connects one of the testers only to the printed board package connected to one of the back wiring boards within the board group based on the test demand signal.
