PURPOSE:To reduce the amount of hardware to facilitate control, by providing a line control word corresponding to the traffic density of a line and by assingning the idle line control word to the line by detection of incoming on this line. CONSTITUTION:When line scan advances to select line incoming detection part 1 and incoming is detected to execute a command, the line number of the incoming line is input to the data register of line control work LCW, and processing request is reported to program control part 7. Program control part 7 can detect the line number for incoming by reading out contents of the data register of LCW and assignes a new line to the free LCW, so that the line can be controlled. |
