Abstract

PURPOSE:To execute transmission and reception of an alarm signal and an order call by connecting a telephone set board in which a terminal telephone set and a control device are connected, to a general subscriber telephone line, after an alarm transfer is ended and when there is no alarm. CONSTITUTION:In a master station 1, a subscriber telephone set 2 of a push- button dial is installed. The telephone set 2 is connected to a switchboard 5 through a subscriber telephone line 3, and is connected to a transmission circuit network control device 7 of a slave station 6 through a subscriber telephone line 3'. A slave station 6 is provided with a telephone set board 14, and a terminal telephone set 15 for a call and a control device 12 for receiving a push- button dial signal and converting it to a control signal for controlling a device in the slave station 6 are connected to the board 14. Also, the board 14 is connected to the general subscriber telephone line 3' after an alarm transfer is ended and when there is no alarm. As a result, transmission and reception of an alarm signal, and an order call can be executed by one subscriber telephone line.
