PURPOSE:To suppress the increase of a required memory quantity, and to save time and labor concerned with a debug and maintenance by separating a common processing independent of the classification of lines to be used, from a processing dependent on the classification of the lines to be used, at the time of operating a line control in a data communication. CONSTITUTION:This system is equipped with a protocol processing module command analyzing part 2 which analyzes a request received from a protocol processing module 1, and a line common processing part 3 which is activated when the analyzed request is common to the line classification, and operates the common processing to the lines. And also, this system is equipped with a line classification dependent processing selecting part 4 which is activated when the analyzed request is dependent on the classification of the lines, and which activates a line classification dependent processing part 5-1 which operates the control corresponding to the line classification. That is, whether the command from the protocol processing module 1 is the common processing independent of the line classification, or the processing dependent on the line classification, is analyzed, and the processing corresponding to each case is operated. Thus, the required memory quantity of a program, and the time and cost or the like concerned with the debug and the maintenance, are reduced.
