Abstract

PURPOSE:To allow a telephone set side to recognize or discriminate the call restricting state by allowing a notice means at the telephone set side to notify the sending stop of a selection signal when a call restriction means of an a connecting device side stops the sending of the selection signal to a telephone line. CONSTITUTION:With a call restriction control switch 23 turned on, the call restricting state is informed to a control section 9. In such a case, with a call signal sent from a telephone set 2 to a connection device 1,the control section 9 controls the call restriction data signal and allows the call reply signal through a control channel. A control section 3 at the telephone set 2 does not output a dial acknowledge voice signal to an amplifier 16 even if a dial key 15 is operated through the input of the call reply signal. As a result, no dial acknowledge tone is generated from a speaker 17 and the call restricting state is informed to the telephone set 2. On the other hand, the control section 3 sends a dial data signal representing an opposite telephone number by the operation of the dial key 15. A control tone 9 of the connector device 1 does not operate a DTMF circuit 18 and the selection signal representing the opposite telephone number signal is not outputted.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Object of the Invention] (Field of Industrial Application) The present invention relates to a method for regulating outgoing calls in a cordless telephone device.

(Prior Art) Generally, a cordless telephone device connects a telephone and a connecting device corresponding to the telephone via a wireless line, and also connects the telephone to a connecting device. A multi-channel access method consisting of one control channel and multiple communication channels is applied to the main line by connecting a wired line on the remote side to the main line. Then, when you make a call from the front side of the phone, the phone is connected to the third
A calling signal consisting of a synchronization signal and an ID signal as shown in the figure is transmitted to the connected device through the control channel 611. When the connecting device receives this calling signal, it transmits an optical call response signal consisting of a synchronization signal, a channel signal specifying an empty communication channel, and an ID signal as shown in FIG. 4 to the telephone set through a controlled tunnel. When each telephone receives this call response signal, it enters a call state at the designated call desend channel. Thereafter, when a dialing operation is performed on the telephone side to specify the telephone number of the other party, the telephone station transmits a signal indicating the telephone number to the connecting device through the communication channel. When the connecting device receives this signal, it sends a selection signal (PB double signal) corresponding to the telephone number to the wired line.

By the way, in a state where call restriction is set, the contact FA device does not send a selection signal to the wired line. However, in the conventional call restriction method, the connecting device unilaterally uses 11i1 for outgoing calls.
Even if J was performed and the call was restricted, the telephone operated in the same way as when it was not in the call restriction state, and when a dial operation was performed, dial l and [acknowledgement tones were generated. Therefore, there was a problem in that the user could not detect the call restriction state. In other words, even in the outgoing call restriction state, it seemed to accept a full Gui A operation and send a selection signal to the wired line, which was extremely unnatural. Additionally, when multiple cordless telephone devices are installed, if one of the telephone devices has outgoing call restrictions set, it is not possible to determine which outgoing calls are restricted at the telephone source side and which are not. There was a serious drawback.

(Problems to be Solved by the Invention) As described above, in the conventional call restriction method, there was a problem in that the telephone number □ side could not detect the optical transmission restriction state.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method for restricting outgoing calls in a cordless telephone device, which allows the telephone station to detect the optical fiber restriction state.

(Measures of the Invention) (Means for Solving the Problems) The transmission restriction method of the present invention is such that when the transmission of a selection signal to a wired line is stopped by the optical transmission restriction means on the connection device side, the optical transmission restriction state is reached. A signal indicating the selection signal is transmitted from the connecting device to the telephone via the wireless line, and in response to the signal indicating the above-mentioned compensation restriction state, the transmission of the selection signal is stopped by the notification means of the eight telephones. A groove is formed so that it is notified.

(Function) According to the optical fiber restriction method of this defense, if the connecting device stops sending selection signals to the telephone line and the outgoing call is restricted, the telephone side will notify the telephone line of the outgoing restricted state. be done.

<Embodiments> Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a cordless telephone device to which the optical fiber regulation method of the present invention is applied, in which a connecting device 1 and a telephone 2 corresponding to each other are connected via a wireless line, and one control channel is connected to the wireless line. A multi-channel access method consisting of multiple call channels is applied.

In this device, when a call is made on the telephone 2 side, the control unit 3 reads out the identification code of the telephone 2 recorded in advance in the ID ROM 4, and sends a synchronization signal and an ID indicating the identification code. A multi-call signal (No. 8) shown in FIG. The receiving unit 7 on the side of the connecting device 1 applies the calling signal received on the control channel via the receiving antenna 8 to the control unit 11 9.

When the control unit 9 receives this calling signal, the
The identification code of the connection device 1 stored in advance in o is read out, and TR confirms that this identification code matches the identification code indicated by the 10 signal included in the calling signal. When the control unit 9 confirms that the identification codes match, it determines the empty communication channel, and sends a second signal consisting of a synchronization signal, a channel signal specifying an empty channel channel, a transmission restriction data signal, and an ID signal. A call response signal as shown in the figure is applied to the transmitter 11. This call response signal is constructed by adding a call restriction data signal indicating the call restriction state to the conventional call signal shown in FIG.
The transmission restriction data signal at this point indicates a state in which transmission is not restricted.

When the transmitting section 11 receives the above-mentioned calling signal, it transmits a calling response signal from the transmitting antenna 12 through the control channel. Thereafter, the control section 9 applies a signal indicating the empty communication channel to the reception section 7 and the transmission section 11, and switches the reception section 7 and the transmission section 11 from the control channel to the communication channel.

The receiving unit 13 on the telephone Orange 2 side transmits the call response signal received on the control channel via the receiving antenna 14 to the control unit 3.
Add to. When the control unit 3 inputs this call response signal,
In addition to confirming that the identification codes match, the transmitter 5 transmits a signal indicating the communication channel specified by the channel signal.
In addition to the receiving section 13, the transmitting section 5 and the receiving section 13 are switched from the control channel to the call channel.
into a call state.

Next, when the dial key 15 is operated on the telephone desk 1 side and the other party's telephone number is suggested to the control unit 3, the control unit 3 applies a dial confirmation audio signal to the speaker 17 via the amplifier 16, and the speaker 17 It generates a dial confirmation sound from the terminal and applies a dial data signal indicating the telephone number of the other party to the transmitter 5. The transmitting section 5 transmits this dial data signal from the transmitting antenna 6 through a communication channel.

The receiving unit 7 on the side of the connecting device 1 transmits the dial data signal received on the communication channel via the receiving antenna 8 to the control unit 9.
Add to. When the control 1 part 9 inputs this dial data signal, it starts the DTMF circuit 1 based on the dial data signal.
8 to cause the DTMF circuit 18 to output a selection signal (PB signal) indicating the telephone number of the other party. This selection signal is sent via the side sound protection circuit 19 to the wired line 20 connected to the exchange side.

In this way, the selection signal is transmitted to the wired line 2o, and as a result, when it is connected to the other party's terminal n, the reception signal is transmitted from the fJ ridge line line 0 → the sound protection circuit 19 → the transmitter 11 → the transmitting antenna 12.
→Receiving antenna 14→Receiving section 13→Receiver 21, and the transmission signal is transmitted from microphone 22→Transmitting section 5→Transmitting antenna 6→Receiving antenna 8→Receiving section 7→Side sound prevention circuit 19→
Transmitted via wired line 2Q. Note that the control is performed in the case of a call as described above, but in the case of an incoming call, an incoming call signal having the same structure as the call response signal is transmitted from the connection device 1 to the telephone 2,
After this, as in the case of a call, connecting device 1 and telephone t! ! 2 are connected by a communication tunnel.

If the call restriction control switch 23 is turned on now, it will be indicated to the control unit 9 that the call restriction state has been reached. In this case, when a call @tan is transmitted from the telephone 2 to the connecting device 1, the control CD unit 9 sends an outgoing call indicating that the optical signal is restricted in the Sanskrit call ri5 answer I= number shown in FIG. The control data signal is controlled and the call response signal is transmitted on the control channel. When the control section 3 on the telephone desk 1 side receives this call response signal, it does not output a dial i recognition voice signal to the amplifier 16 even if the dial key 15 is operated.

As a result, the dial confirmation sound is not generated from the speaker 17, and the telephone/telephone 2 side is notified that the outgoing call is restricted.

On the other hand, in response to the operation of the dial key 15, the control section 3 causes a dial data signal indicating the telephone number of the other party to be transmitted through the communication channel. The control sound 9 on the connecting device 1 side is D
The TMF circuit 18 is not activated. Therefore,
The DTM F circuit 18 does not output a selection signal indicating the telephone number of the other party.

In this manner, in the Sanskrit 1114 state, even if the dial key 15 is operated, the dial TiftQ sound is not generated, so that the telephone 2 side can detect the outgoing call restriction state.

In the above embodiment, the dial I95. Although the call restriction state is notified by making a sound) 2, the present invention is not limited to this, and an alarm sound indicating the call restriction state may be generated from Subinono 17. .

(Effects of the Invention) As explained above, according to the present invention, when the transmission of a selection signal to the telephone line is stopped due to the calling restriction state on the connecting device side, the transmission of the selection signal is performed by the notification means on the telephone n side. Since the outage is notified, the telephone can be informed of the status of the optical communication standard by the side.Also, when multiple cordless telephone devices are installed, it is possible to restrict outgoing calls to one of the telephone devices. Even if there is a setting, there is an advantage in that the telephone system can distinguish between those that are restricted and those that are not.
