Abstract
PURPOSE:To facilitate a dial operation and to prevent the dial operation from being performed erroneously, by selecting a name column on a presence/absence panel according to a telephone set code inputted from a central control unit in a display panel controller, and next, displaying presence/absence status set in advance based on a dial code received from a call issuing telephone set on the presence/absence display panel. CONSTITUTION:The central control unit 14 receiving the presence/absence display request of a caller who hears an outgoing tone connects a call issuing line 40 to the display panel controller 30 via a connection path C2 by controlling a main switch 12. When the call issuing line 40 is an extension, since the central control unit 14 decides it as extension outgoing, line information based on the line position of the call issuing line 40 or the telephone number of an accommodated telephone set is extracted, and it is transmitted as the designation information of the name column to the display panel controller 30. The display panel controller 30 receiving the information of the call issuing line selects a corresponding name column on the presence/ absence display panel 20. Next, the display panel controller 30 refers to the display information of the presence/absence status by the dial code, and displays the presence/ absence status of received information on the selected name column of the presence/ absence display panel 20.
