PURPOSE:To give the control to both the service control information and the terminal control information by the input device connected to the basic service offer exchange device, by installing the transmission means for transfer of the subscriber data between the above-mentioned exchange device and the additional service offer device. CONSTITUTION:Data terminal unit 100 is stored into circuit exchange station 20 via remote line concentration station 10, and additional service offer device 30 is connected to station 20. And the bus for subscriber data transfer is provided in addition to transmission line 240 between unit 100 and device 30. Then in case the control information is rewritten for both the basic and additional services, the service control information is supplied from input/output device 220 based on the slip. Thus central processor 210 edits the basic service control information to be stored into secondary memory device 230, and then transmits the additional service information and a series of command information to device 30 concurrently with the rewriting and via buses 260a and 260b. And central processor 310 carries out the rewriting for the additional service information of secondary memory device 330 based on the command. |
