Abstract

PURPOSE:To realize the accurate transmission without impairing the data transmission efficiency by transmitting the affirmative answer signal indicating that the data sent from the transmission station has been received at the reception station to the transmission station in an assured way. CONSTITUTION:The transmission data is transmitted in series based on the format shown in the diagram. In other words, the format comprises the following elements: control code A showing the start of the transmission data; reception device number B (designation of reception STN); RPT showing whether the transmission data is the first or second time; transmission device number C; actual transmission data D; error test code F to the transmission data of A-E; code filed AK(1) which is used when repeating STN transmits by itself the check result of the reception data; and code field AK(2) which is used when designated reception STN transmits the answer signal.
