PURPOSE:To control a customer station equipment, by outputting an automatic answering message through the use of a voice LSI, storing the content of message after converting it into a digital signal and discriminating a PB signal. CONSTITUTION:In case of the operation of an automatic answering telephone system, when a call signal comes in connecting a telephone line 1 to a line controller 6 by switching a switch 2, a signal transmitter/receiver 18 detects it, a switch 5 is changed over with the output and the line 1 is connected to a PB signal discriminating circuit 7. Simultaneously, a logical operation circuit 8 is started and when the PB signal is not incoming next, an automatic answering voice message is outputted from the LSI9 to the line. A voice signal from the line is converted into a digital signal at the LSI9 and stored in an RAM10. The stored sound message is reproduced with an operation switch 23. When the PB signal comes from the PB signal, it is discriminated at the discriminating circuit 7, a device monitor controller 15 is driven to control a terminal device 16 or monitor the state. |
