    • A data communication apparatus includes a receiving unit for receiving data, a memory for prestoring data of multi-address called stations, a sending unit for sending the data received by the receiving unit in a multi-address calling mode, a unit for receiving an instruction signal for instructing multi-address calling from a relay request station, and a control unit for causing the sending unit to perform multi-address calling to the multi-address called stations stored in the memory in response to reception of the relay instruction signal. The control unit checks whether or not a multi-address called station stored in the memory is the relay request station, and inhibits multi-address calling to the relay request station in accordance with the checking result.
