Hereinafter, the present invention will be explained in detail with reference to figures showing examples.

FIG. 2 is a block diagram showing the entire configuration, in which lines 1□ to 1n such as reeds and office lines are accommodated in the main device 2, and telephones 3. ~c and multiple types of non-telephone terminals 4~4n are housed as slave units, and the main device 2 includes a communication path switch 5, a receiving trunk 6 as a signal detection means, and a device for transmitting recorded voices, etc. A response trunk 7 is provided, and for example, when a calling signal arrives from line 1□, the DC loop is closed in response, and the path □ shown by the dotted line is closed.
The response trunk 7 starts sending a response message, and when an automatic signal S used between non-telephone terminals arrives from the line 1□, it is sent to the receiving trunk 6 according to the type of non-telephone terminal. to detect each individual,
Accordingly, the corresponding non-telephone terminal 41 is selected, and the path ■ is exchanged and connected, and a calling signal is sent to the non-telephone terminal 4□. If the automatic signal S cannot be received within the specified time, the path is passed. Switch to the exchange connection of ■, telephone 3□~
At the same time, a calling signal is sent to both.

However, if there are a plurality of non-telephone terminals of the same type among the non-telephone terminals 4□ to 4n, a calling signal is sent to these terminals simultaneously or according to a predetermined order.

Note that the response message is sent by the response trunk T.
This continues until the automatic signal S is received or the switch is made to path (2). However, if the non-telephone terminal 41 is in communication, the DC loop is immediately opened and the line is disconnected after detecting the automatic signal S.

FIG. 1 is a block diagram showing details of the main device 2. For simplicity, the line 1i, telephone 31, and non-telephone terminal 41 are shown in FIG.
Although only shown, the main device 2 includes a calling signal detection circuit 11 that detects the 16H7 calling signal, a calling signal generator 12 that sends out the 16H2 calling signal, an automatic signal S generator 13, and A switch group 14 is provided for sending each output to the telephone 31 or non-telephone terminal 41, and a control section 15 consisting of a processor such as a microprocessor and a memory is further provided.
is equipped with a signal receiver corresponding to an automatic signal S of a specific frequency that differs depending on the type used to confirm the other party's terminal, while the response trunk 7 has a plurality of recorded response messages each having a different response message depending on the type of non-telephone terminal. Trucks are ready.

Further, depending on the situation, the calling signal detection circuit 11 may be configured such that, for example,
．． The ring signal generator 12 also has a function of receiving a ringless ringing signal at a specific frequency of 3KH, and a function of transmitting a similar ringless ringing signal.

The control unit 15 controls the call path switch 5, the response trunk 7, each generator 12, 13, and the switch 14 according to the detection power of the calling signal detection circuit 11 and the receiving trunk 6, and controls each cross point ~X5 and Xll~X
By driving tS, it performs the above-mentioned exchange connection and sends out each signal, and also receives the DC loop closure detection force based on the responses of the telephone 3I and non-telephone terminal 41 by the relay etc. in the calling signal generator 12. Each of these situations is sequentially stored in memory as data, and control decisions are made based on this data.

FIG. 3 is a flowchart showing the operating status of the calling side non-telephone terminal, and FIG. 4 is a flowchart showing the control status of the control unit 15 corresponding to FIG. 3. In FIG.
