Abstract

PURPOSE:To enhance both the transfer efficiency and the reliability by securing a switch to the error correction control in case many data errors exist due to the noise of the transmission line. CONSTITUTION:In the normal time, the transmission data is transmitted to transmission line 5 from memory 1 via control part 2, switch part 11, error detection code control part 3 and transmission part 4 respectively. When the error occurrence frequency detected at the receiver side exceeds the prescribed value due to the noise increment at the transmission line, control part part 11 and switch on switch part 10 is actrated to switch off switch part 11 and 12 respectively. Thus, the error detection control mode is switched to the error correction control mode, and the data error is corrected at the receiver side.
