PURPOSE:To relieve the load of the processing of a computer in retransmission correction by dividing an information code part to parts corresponding to plural terminal device, and dividing again the parts into an information code, a retransmission correction control code and an exchange control code. CONSTITUTION:A reception section R receives a signal from a high-order station. A master clock source C of a terminal Ti station is adjusted automatically by voltage control. A sample value data system TI detects timing information of a bit clock of the Ti. A PR consists of a shift register, ''0'' detection circuit and a buffer resister, and inputs a code word subject to error corection to a buffer SR for code transfer between a transmission system and a terminal device. Channels S1, R1 transmit information block, channels S2, R2 transmit the next information block or request retransmission and the control code such as interruption is transferred by channels S3, R3. Complicated control is attained without imposing a considerably load on a communication program by dividing the S2, R2 further in details. |
