Abstract

PURPOSE:To send a touch-tone signal to the terminal of the opposite party of communication without necessitating a touch-tone signal sending device by sending the touch-tone signal by the dial of an opposite party extension telephone set when the specified terminal set so as to be capable of sending the touch-tone signal turns into an extension communicating state with an extension telephone set. CONSTITUTION:The touch-tone signal sending device 4, a touch-tone signal sending means 7, and a touch-tone signal sending setting storage means 8 capable of setting whether the touch-tone signal is to be sent or not for every terminal connected to an exchange are provided. Then, when the specified terminal set so as to be capable of sending the touch-tone signal turns into the extension communicating state with the extension telephone set 1, the touch-tone signal is sent by the dial of the opposite party extension telephone set 1. Thus, even a multifunctional telephone set or a rotary dial telephone set, etc., not provided with the touch-tone signal sending device 4 can send the touch-tone signal to the specified extension terminal of the opposite party by dial operation when it turns into the extension communicating state with this extension terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a plan-phone signal sending method used in private automatic branch exchanges and the like.

2. Description of the Related Art In recent years, there has been an increase in the number of terminals such as voice mail devices and presence display panels that automatically answer extension lines and provide various services using buzzer/phone signals. In order to use these terminals, the conventional touch-tone signal transmission method is used when a multi-function telephone equipped with a touch-tone signal transmission device or a standard standard telephone such as the 601P type is connected to an exchange. By dialing while the telephone was on a call, a touch tone signal could be sent from the telephone's own signal source to the other party's terminal through the communication path.

Problems to be Solved by the Invention However, since the above-mentioned conventional push-tone signal output method relies on the telephone that performs the dialing operation, multi-function telephones and rotary telephones that do not have a push-tone signal transmitter do not have the ability to communicate with the other party. There was a problem in that it was not possible to send a Gunong Yuhon signal to the terminal.

The present invention is intended to solve these conventional problems.
It is an object of the present invention to provide an excellent method for sending out touch-tone signals that makes it possible to send out touch-tone signals without depending on a telephone that performs dialing operations.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a push-tone signal transmitting device, a touch-tone signal transmitting means, and a touch-tone signal transmitter that allows setting whether or not to transmit a touch-tone signal for each terminal connected to an exchange. A setting storage means is provided, and when a specific terminal set to be capable of transmitting a touch tone signal is in an extension conversation state with an extension telephone, a push tone signal is transmitted through the dial of the other party's extension telephone.

Therefore, according to the present invention, it is not only necessary to set a specific extension terminal to send a touch-tone signal, but even multi-function telephones, rotary telephones, etc. that do not have a touch-tone signal sending device can connect this extension terminal and an extension. This has the effect that when a call is established, a touch tone signal can be sent to the other party's specific extension terminal by dialing.

Example FIG. 1 shows an embodiment of the present invention.

In FIG. 1, a main switch 5 constituting a private branch exchange is connected to a central control unit 6, and is also connected to an extension telephone 1 and an extension terminal 2 such as a voice mail via a subscriber circuit 3. A push-tone signal transmitting device 4 is also connected. Note that the subscriber circuit 3 is connected to the central control unit 6.
connected and controlled. The central control device 6 also includes a touch-tone signal sending means 7 and a touch-tone signal sending setting storage device 8.

FIG. 2 shows the memory contents of the touch tone signal transmission setting storage device. FIG. 3 shows the processing flow from dial reception to touch tone signal transmission.

Next, the operation of the above embodiment will be explained. When an extension telephone dials an extension terminal (extension number 201) during an extension call, the central control unit performs processing as shown in the processing flow of FIG. First, it is determined whether an extension call is in progress. If an extension call is in progress, then it is set in the touch-tone signal transmission setting storage device to determine if the touch-tone signal transmission town corresponding to extension number 201 is/is not possible, and if it is a push-tone signal transmission town, the extension terminal (number 201) is set. Performs push-tone signal transmission processing for the

In the touch-tone signal sending process, a touch-tone signal sending device uses a touch-tone signal sending means to send a touch-tone signal to an extension terminal.

In this way, according to the embodiment described above, by setting the touch tone signal to be sent to a specific extension terminal, it is possible to call the other party's specific extension terminal by dialing into the extension call state, without depending on the extension telephone that performs the dialing operation. This has the effect of being able to send out touch-tone signals.

Effects of the Invention As is clear from the above embodiments, the present invention has the following effects.

(1) By setting a fixed extension terminal to send a touch-tone signal, it is possible to send a touch-tone signal to the other party's terminal by dialing even a rotary dial telephone, etc., without depending on the extension telephone that performs the dialing operation.

(2) The sound source of touchtone signals can be shared and unified within the exchange.
