Abstract

PURPOSE:To send normal data from a terminal equipment through a half-duplex data transmission system, by allowing a center to send out an answer signal to the terminal equipment after the data transmission from the terminal equipment is completed. CONSTITUTION:In the half-duplex data transmission system wherein the center is connected directly to terminal station equipments 21-2n, and 31-3n without using any modem, a timer 9 which is actuated every time a minimum unit of data is transmitted from said terminal equipment and has timer time set longer than at least the minimum unit time of data is provided to the center 1. Then, answer signal transmission from the center 1 to the terminal equipments is delayed until the timer 9 reaches the timer time. The center 1 is allowed to send an answer signal to the terminal equipments 21-2n, and 31-3n after data transmission from the terminal equipments 21-2n, and 31-3n is completed.
