Abstract

PURPOSE:To improve the efficiency of data transfer, by detecting a ratio of error generation in transferring data, and switching length of information to be transferred corresponding to the quality of a line to be used based on a detected result. CONSTITUTION:Transfer data sent from a CPU13 is inputted to a communication control part 14, and is counted by a transmission counter 15. The counter 15 outputs a count value to the control part 14, and is reset at every value M. A data length setting part 18 inputs the transfer error information of a terminal equipment 12, and accumulates the number of times of errors, and tabulates the number of times of errors simultaneously with the clearing of the counter 15. The number of times of errors is compared with a decided number of times, and the data length is set based on the result, and the result is informed to a data generation part 17. The generation part 17 switches the data length dynamically by cutting the data length when the quality of the line is worse based on the signal from the setting part 18, and extending the data length when satisfactory quality is obtained. Thereby, it is possible to improve the efficiency of the data transfer.
