Abstract

PURPOSE:To ensure an assured synchronizing operation through a transmitter of the transmitting side, by providing a field at a part of a slot in order to transmit the state of a transmitter of the receiving side to the transmitter of the transmitting side. CONSTITUTION:Transmitters 1a-1c are connected via a transmission line 2, and terminals are connected to these transmitters respectively. A controller 4 monitors and controls the line 2. When the sending-back of an affirmative answer 32 is over at the receiving side of the transmitter, a status bit 61 is set in a busy state. Then the information showing the ready stare is put on the bit 61 to be transmitted. A data transfer slot 33 arriving later is received assuredly and processed. On the other hand, the transmitter of the transmitting side prepares for reception of the data when it receives a slot 32 showing an affirmative answer. After the preparation is over, the conditional data is transmitted. Then the actual transmission is started after the transmitter of the receiving side detects the ready state.
