Abstract
PURPOSE:To improve the reliability by setting a specific wait time to each terminal equipment connected to a transmission line, counting the time from a point of time in the absence of a carrier on a transmission line when a transmission packet is received, thereby transmitting acknowledge packet when the waiting time specific to its own terminal equipment comes. CONSTITUTION:A reception address 10 is set to plural terminal equipments 21-26 connecting to a transmission line 20, it is stored in a data area 11 and the packet is sent. In this case, assuming that terminal equipments 24-26 receive the packet and terminal equipments 21-23 do not receive packet, then an acknowledge packet is transmitted from the terminal equipments 24-26 as described in the following. That is, the relation of T24<T25<T26 is decided, where T24, T25 and T26 are specific waiting times. The time is counted after a time A when the transmission packet 30 is finished and the carrier is lost and the packets 31-33 are sent after the specific wait time of its own terminal equipment is eliminated. Thus, even when plural terminal equipments exist to one packet transmission, the reliability of data transmission is improved.
