Abstract

PURPOSE:To prevent confusion of communication between a station and an opposing station, by passing under-run or over-run state produced on a transmission and reception buffer on a data transmission/reception circuit, through the connection of a buffer controlling circuit to a timing forming circuit of a line individual control section. CONSTITUTION:A line common control section 1 is connected to a transmission line 3-1 and a reception line 3-2 via an individual line control section 2''. A data transmission/reception circuit 2-2 is connected to the control section 2'' via an interface circuit 2-3, and transmission and reception buffers 2-4 and 2-5 are connected to the circuit 2-2, and also a buffer controlling circuit 2-7 connected to a timing forming circuit 2-6 is connected to the circuit 2-2. Detection signals (a), (b) from the buffers 2-4, 2-5 are applied to the controlling circuit 2-7, transmission and reception buffer timings ST', RT' from the circuit 2-6 are applied to the control circuit 2-7 and the circuit 2-2, where under-run and over-run of transmission and reception are detected.
