The call path switch 10 switches the connection between the outside line 21, the inside line 31, and the inside line 31 under the control of the connection control unit 50. The outside line circuit 20 accommodates a switching break line 22 of the exchange and is connected to the speech path switch 10 as an outside line 21.

The extension circuit 30 connects extension lines 31 to the speech path switch 10 and terminates the telephones 41 to 43 at these extension lines 31. The off-hook telephone 41 is a telephone in an off-hook state, and the multi-function telephone 43 has function buttons, a character display, a speaker and the like.

The connection control unit 50 controls the call connection of the telephone device by a program and data. The operation procedure of this embodiment will be described later with reference to FIG. The line state memory 51 obtains and stores the state information of the outside line 21 and the inside line 31 from the connection control unit 50.

The Howrah signal detection unit 61 is connected to all the line numbers L1 to LN of the subscriber line 22 which becomes the outside line 21, and when the Howrah signal is received, as the outside line information of the outside line receiving the signal, for example, the line number L1. Is output to the connection control unit 50 together with the signal detection information of the Howra signal. The howler information notification unit 62 is driven by the connection control unit 50 when the connection control unit 50 receives the signal detection information of the howler signal, and gives predetermined notification information, for example, voice information "41st handset is out of contact", Character information such as "41: Handset off" is output. These outputs are connected to, for example, the multi-function phone 43 preset by the connection control unit 50.
