Abstract

PURPOSE:To use just one piece of the transmission/reception circuit that is provided to a line concentration repeater to the slave stations and at the same time realize a transmission of data among a plural number of slave stations, by starting a communication between a master station and the slave stations by transmitting the synchronous signal to the line concentration repeater and carrying out a transmission of data between the slave station and a master station in the switching time band of the circuit. CONSTITUTION:When the special synchronous signal A is received from the master station, the slave station NO.0 is first selected. Then the signal X1 sent from the master station is sent to the timing control circuit 36 from the interface 35 as the reception data RD and to the interface 37 from the circuit 36 as the transmission data signal SD to be transmitted for a fixed time t1 to the slave station No.0 via the switch circuit 38. After the slave station No.0 receives the signal X1, in a fixed time t2 later the station No.1 transmits only for a fixed time t3 the signal Y including the data and the synchronous signal Z to the line concentration repeater 3. These signals are received at the interface 37 as the reception data RD and transmitted as they are to the master station 1 from the circuit interface 35 via the control circuit 36.
