Abstract

PURPOSE:To transmit attendance/leaving information by using an existing line, by connecting a modem phone having an automatic incoming/outgoing function to respective controllers to which plural display operating terminals are connected, and connecting them mutually with a telephone line. CONSTITUTION:By turning ON an operating switch corresponding to the person of a display operating unit 1A in a system A, the controller 2A transmits data to a corresponding operating unit 1A by a multiplex transmission system when the data is included in a registered address. In case the display destination of the attendance/leaving information received by the controller 2A includes the terminal equipment 1B of another system B, the modem phone 3 is operated, and the automatic dialing of the line number of the controller 2B is performed. A called modem phone 3B transfers the attendance/leaving information to the controller 2B via a line 4. The controller 2B extracts display data when the data is included in the registered address, and sends the data to the display operating unit 1B.
