Abstract

PURPOSE:To make the amount of hardware small and prevent the influence upon the processing capability of a common control unit by storing the state of all lines into a temporary memory unit each time the state of lines is changed. CONSTITUTION:Temporary memory unit M stores the line state under the control for the call processing of common control unit CC. Display unit DISP has a display equipment and group number buttons. Group selection register REG selects a line group to be displayed on a basis of indication from display unit DISP. Display equipment driving unit DV reads out successively the line state of the line group, which is selected by group selection register REG, from the temporary memory unit periodically and drives the display equipment of display unit DISP. Then, the line state is displayed on the display equipment provided for every line group.
