The single telephone interfaces 4a, 4b-4n are provided with dial detecting means 6a, 6b-6n for detecting dial signals from the connected single telephones 2a, 2b-2n, respectively, and the device 1 further includes the single telephones 2a, 2b. Storage means 11 for storing the single telephone connection status for each of ˜2n and judgment means 10 for changing the single telephone connection status stored in the storage means 11 based on signals from the dial detection means 6a, 6b to 6n. And the presence or absence of connection of the single telephones 2a, 2b to 2n is automatically detected .
[0006]
[Action]
For the single telephone interfaces 4a, 4b to 4n, the contents of the single telephone connection status in the storage means 11 indicating the connection status of the single telephones 2a, 2b to 2n are set to “None” indicating no connection as an initial value. . The judging means 10 monitors the dial detecting means 6a, 6b- 6n of the individual telephone interfaces 4a, 4b-4n, and when it judges that all or part of the effective dials has been detected, the individual telephone interfaces 4a, 4b. ~4n shows the state in which a connection from the "no" indicates a state without connecting the contents of a single telephone connection status indicating a connection state of the memory unit 11 corresponding "Yes" to change to, thereafter referring to the storage means It can be determined that it is connected.
