Abstract

PURPOSE:To enable simultaneous reception of the same data for all the controlled stations, by coupling the signal to the reception point at the multi-drop point so that it is distributed, after the signal passes through all the transmission points at the multi-drop point. CONSTITUTION:The down stearm transmission bus 61 becomes the upper stream trasmission bus 52 after it passes through through all the transmission points of the controlled stations 71 to 7N and the control station 50 and turns back after the final controlled station 7N, and reaches the control station 50 after passing through all the reception points of the controlled stations 71 to 7N. Accordingly, the control station 50 and the controlled stations 71 to 7N can receive the same data at the same time.
