Abstract

PURPOSE:To enable the control achieving the saving of power, by controlling the display lamp for all the lines to be displayed and distinguishing the lamp for the line not required after catching the line, in requiring the catching of selection of line at transmission and response. CONSTITUTION:The button telephone main device ME and the button telephone set TEL are connected with a control line 0, and the button information and the hook information HS such as main trunk button information LK0-n and extension button information A0-n with the operation of the transmission data input circuit 8 of the telephone set TEL are stored in the reception data memory circuit 3 via data transmission/reception circuits 1, 2. Based on the stored information, the line lamp control information is formed with the other main trunk information at the transmission data input circuit 7. This information is fed to the reception data memory circuit 4 to output the line lamp control information to the reception data output circuit 10. Further, at transmission and response, if the line selective catching is required, the display for all the lines is controlled, the display of the line not required after the line catching is distinguished to save the power.
