PURPOSE:To attain the high speed and massive sending of a display data by separating a voice data and a display data and sending the result to an attendant board after multiplexing a display data in a lump managing memory into a voice data to transmit it. CONSTITUTION:When a display request such as a character data is given to the attendant board 11, the request is sent to a central controller 16, the controller 16 gives the command of read of a data D and its output to a data base 22 in which the display data D is stored. On the other hand, the controller 16 connects the board 11 having a display request with the output of a data line controller 21 from which the output of the data D is given to constitute a data link 24, and the data link controller 21 applies the multiplex between the data D and a voice data V and the result is sent. Thus, the data D is sent to an attendant board interface 13 from the controller 21 via the link 24, multiplexing information is separated by an interface 13 and the data V is displayed to the channel of the board 11 and the data D is displayed on the board 11. |
