Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a configuration diagram showing an embodiment of a data transmission device of the present invention. Prior to this, a general connection configuration of the data transmission device will be described.

<< General Connection Configuration >> FIG. 2 is an explanatory diagram showing a case where a call is made by an on-hook dial in a general connection configuration of a data transmission device. In the figure, the data transmission device 1 is, for example, a terminal adapter for ISDN. Further, the data transmission device 1 is connected to the data terminal 2 via the digital interface and to the analog line telephone 3 via the analog interface. The data transmission device 1 is configured to connect the data terminal 2 and the telephone 3 to ISDN, which is a digital public network.

In such a configuration, when making a call using the on-hook dial as shown in the figure, the procedure is as follows. A dial command is input from the data terminal 2 in the call mode. That is, a predetermined call mode is selected from the data terminal 2 and a dial number such as 123-4567 is input. As a result, the data transmission device 1 performs a calling process to the digital public network, and when the other party recognizes that the other party has responded, the data transmission apparatus 1 uses the speaker provided inside to notify the other party of the response. Output (performed by voice from the other party, stop of ringing sound, etc.). The operator lifts the handset of the telephone 3 to start a call.

A case will be described below in which communication connection is performed with the hook switch of the telephone set closed (off-hook state). FIG. 3 is an explanatory diagram when a call is made from such a telephone. The configurations of the illustrated data transmission device 1, data terminal 2, and telephone 3 are the same as those in FIG. 2 described above, and the operation thereof is as follows. Lift the handset of telephone 2 and dial from telephone 2. The data transmission device 1 performs a calling process to the digital public network, and when the other party responds, calls this to the telephone 3
To be transmitted. The operator confirms the other party's response with the handset and starts the call. In other words, in this case, there is no operation of the data terminal 2 and only a normal call operation is performed.

With such a configuration, when making a call using the on-hook dial in the case shown in FIG. 2, if the caller and the data transmission device 1 are far apart or in a separate room, the response of the other party cannot be recognized. It will be.

FIG. 4 is an explanatory diagram of this state. A dial command is input from the data terminal 2 in the call mode. The data transmission device 1 performs a calling process and outputs a response voice from a speaker when the other party responds. However, since the caller operates in a separate room, the response sound output from the data transmission device 1 cannot be heard, and it is impossible to confirm whether or not the other party is responding.

As described above, when the data transmission device 1 is installed in a separate room from the sender, it is difficult to confirm the response from the other party. Therefore, in the present embodiment, the response from the other party is transmitted. It is configured to notify the telephone set 2, which will be described below with reference to FIG.

<< Embodiment >> In FIG. 1, a data transmission device 10 is a terminal adapter for accommodating a data terminal 2 and a telephone 3 and for communicatively connecting them to a digital public network. The unit 12 is provided.

The main control unit 11 has various functions as a terminal adapter. For example, the main control unit 11 performs a calling process, outputs a response of the other party from a speaker, and when there is a response from the other party, a response is made. It has a function of instructing the confirmation signal sending unit 12 to output a response confirmation signal.
The response confirmation signal transmission unit 12 has a function of transmitting a RING signal (intermittent signal of 16 Hz) as a response confirmation signal to the telephone 3 when the instruction of the response confirmation signal is received from the main control unit 11. That is, this RING signal is a signal used to ring the bell of the telephone 3 when a call is received from the other party.

Next, in the data transmission apparatus 10 configured as described above, a case where the data terminal 2 makes a call operation in a call mode will be described. A dial command is input from the data terminal 2 in the call mode. In the data transmission apparatus 10, the main control unit 11 performs a calling process to the digital public network, and when the other party recognizes that the other party responds, the other party responds by the speaker provided inside. This is output as a voice, and the response confirmation signal transmission unit 12 is instructed to transmit a response confirmation signal. As a result, the response confirmation signal sending section 12 generates a RING signal and supplies it to the analog interface. The bell or the like of the telephone 3 rings, and the caller can confirm the response of the other party in another room.

As described above, even when the data transmission device 10 and the telephone 3 are in separate rooms, the response from the other party can be recognized as a ringing of the bell, which improves the operability for the caller and the data transmission device 10 Since the telephone and the telephone do not have to be close to each other, the degree of freedom of the installation place of the data transmission device 10 can be increased.

In the above embodiment, the normal RING signal is used as the response confirmation signal, but the present invention is not limited to this. For example, a normal voltage change pattern of outputting for 1 second and resting for 2 seconds is used. Instead, it may be an arbitrary pattern different from the normal calling time, such as a pattern of outputting for 1 second and resting for 1 second.

Further, in the above embodiment, the data transmission device 1
Although 0 has been described as a terminal adapter for a digital line, other than this, for example, a modem for an analog line may be used. That is, in FIG. 1, when the data transmission device 10 is a modem, the communication line is only an analog network, and the other configurations are the same.
And in this case as well, if there is a response from the other party,
The response confirmation signal sending unit 12 of the data transmission device 10 is the RIN
By generating a G signal and sending it to the telephone 3, the response from the other party can be confirmed.

[0021]

As described above, according to the data transmission apparatus of the present invention, when a call is made from the data terminal in the call mode, when the other party responds, the telephone confirms the response. Even if the distance between the data transmission device and the telephone is long, it is possible to surely confirm from the other party, and it is possible to increase the degree of freedom of the installation place of the data transmission device.
