Upon receiving this extension number (2100), the extension telephone 32 is called.

[0005]

As described above, in the conventional exchange system connected by the dedicated line 31 of the individual line signaling system, the exchange b on the calling side has the type of the caller (that is, the caller's type). Regardless of the type of equipment used, only dial transmission is performed to specify the called party (in this case, the extension telephone 32). Therefore, the exchange a on the receiving side does not know the type of the device used on the exchange b on the transmitting side, and there is a problem that the information of the calling party cannot be transmitted to the called party before the call is answered.

The present invention has been made in view of the above circumstances, and an object thereof is an exchange capable of discriminating a calling party (that is, a calling side device) from a change in ringing tone before answering a call. To provide a system.

[0007]

In order to solve the above-mentioned problems, the exchange system of the present invention, which is connected to each other by a dedicated line of an individual line signal system, is a device used by a caller in a switch which is a transmission side. A type signal sending unit for sending a type signal indicating the type of a ring tone signal output unit for outputting a ring tone signal corresponding to the type of device used on the calling side to the exchange on the receiving side; And a control unit that controls the ringing tone signal output unit to output a corresponding ringing tone signal based on the received type signal.

[0008]

In the transmitting side exchange, when the device used by the caller is, for example, an extension telephone, the type signal transmitting section sends a signal indicating, for example, number 1 attached to the extension telephone in advance.
It is added to the beginning of the number of the extension telephone on the called side and sent to the exchange on the receiving side.

The control unit of the exchange on the receiving side recognizes that the device used by the caller is an extension telephone, based on the data of number 1 added to the beginning of the transmitted number string data, A control signal for instructing the call from the extension telephone is output to the ring tone signal output unit. A ringing tone pattern corresponding to each device is preset in the ringing tone signal output section. Therefore, in the ringing tone signal output, based on the control signal from the control unit, a ringing tone signal having a pattern corresponding to the instructed device is sent to the extension telephone, and a ringing tone having a fixed pattern is sent from the extension telephone. ..

As a result, the called party can determine the type of device used by the calling party from the pattern of the ringing tone before answering the call. That is, it is possible to roughly recognize who the caller is.
