Abstract
PURPOSE:To construct a system with an existing private branch line without providing a private line, by connecting a display operating unit on which a modem phone having an automatic incoming function is attached to a controller via a private branch telephone exchange. CONSTITUTION:By turning ON an operating switch corresponding to a person desired to be transferred by a display operating terminal equipment 1, attendance/leaving information is inputted, and the abbreviated dial button of the modem phone 2 is operated, then, the automatic dialing of the extension number of the controller 5 is performed. The exchange 3 connects the modem phones 2 and 4, and the controller 5 extracts display data, and the modem phone 4 calls the modem phone on which the display operating terminal equipment to display the information is attached. When an incoming call is received by the modem phone at the side of the display operating terminal equipment, the controller 5 is connected to the display operating terminal equipment with the private lines 6, 6, then, the data is outputted. The display operating terminal decodes sent data, and displays attendance/leaving by turning ON and OFF the display lamp of a corresponding name plate.
