ABSTRACT:
The PLC20adaptor corresponding to a power line communication apparatus has four PLC bridges30A to30D, each of which is correspondingly connected to Ethernet communication connectors26A to26D, operation mode setting switches27A to27D, display units28A to28D. Each PLC bridge30A to30D includes a PLC modem unit301, a bridge unit302, an Ethernet IF unit303, and a communication control unit304. The communication control unit304obtains data type information on the basis of setting conditions of switches27A to27D corresponding to each communication port. Since the time slot required for the communication link corresponding to the communication port of the PLC network can be obtained on the basis of the data type information, the reservation request can be transmitted to the control terminal.
