PURPOSE:To execute various services, by enabling the main trunk incoming response with an arbitrary extension at night, through the provision of means which change over the state of day and night and incoming display means independently of the incoming storage memory and the extension telephone sets with a signal control processor. CONSTITUTION:A scattered control type automatic exchanger is constituted with a signal control processor 100 which controls signals incoming from devices connected to channel network and those transmitted to external devices, and a connection control processor 101 making the control for channel network and by connecting the processors 100, 101 with a channel switch 103. To the processor 100, a day/night status switch 107, an incoming display device 108, a temporary storing memory 109 and a temporary storing memory control circuit 110 are connected. The switch 107 is changed over according to the state of day and night, the incoming call of the extension 104 and main trunk 105 is detected with the processors 100, 101, and the response of incoming call is enables with corresponding processors 101, 100, allowing to execute various services. |
