Abstract
A data communication apparatus comprises: a memory to store data which is sent from a station for requesting the repeating multiple-address transmission; a transmitter to transmit the data stored in the memory to a repeating multiple-address reception station; a discriminating circuit to discriminate whether the transmission from the request station has been performed via a first route or via a second route; and a deciding circuit to decide whether the repeating multiple-address transmission is performed to the repeating multiple-address reception station or not on the basis of the discrimination by the discriminating circuit. The first route is the route via the telephone network for use in communication of voice and data. The second route is the route via the data communication network only for use in data communication. By previously storing the data of the repeating multiple-address reception station corresponding to the station for requesting the repeating multiple-address transmission, the repeating multiple-address transmission can be performed without instructing the repeating multiple-address reception station from the request station.
