Abstract

PURPOSE:To reduce the useless time and to increase the transmission efficiency, in the N:M time sharing multiplex transmission system by star coupler constitution, by respectively providing the delay circuit with each remote station. CONSTITUTION:The remote station AM1 having the longest transmitting distance from the traffic controller TC transmits the data to the objective remote station via the star coupler SC2 for data at the center by superimposing on the transmission data of the station, when it receives the time slot TS1. In this case, the signal delay time of AM1 to the TC, synchronous and control star coupler SC1 is td1=tdmax. On the other hand, the remote stations AM2-AMn receive the time slots TS2- TSn corresponding to them in the delay times td2, tdn and give the delay compensation time Delay2-Delayn while the data transmission after the reception, so that different fields can not be duplicated on SC2. This compensation time is 2(tdmax-td2) at AM2.
