摘要:
In a method for shifting down a data transmission rate at a transmitter in response to a request from a receiver for retransmission of data frames having data errors in a digital transmission system such as a facsimile system, when transmission errors occur, the receiver transmits a request to the transmitter for retransmission of one or more data frames for which one or more data errors have occurred. At the transmitter, the data transmission rate is shifted down from the first data transmission rate to a second data transmission rate which is used for retransmitting the data frames for which one or more data errors have occurred. The above shift-down operation is controlled by calculating an expected value indicating a possibility of the occurrence of a data error at the time of retransmitting the data frames in which one or more data errors have occurred, on the basis of a number of data frames requested to be retransmitted and a total number of data frames which have been transmitted from the transmitter to the receiver.
