[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dial control system for a terminal device which is connected to a telephone line, accommodates an external telephone, and sends a dial signal from the accommodated external telephone to a telephone line.

[0002]

2. Description of the Related Art A terminal device of this type includes an operation unit such as a dial key, captures a connected telephone line when an off-hook is detected, and operates a dial key when the dial key is subsequently operated. The dial signal corresponding to is sent to the telephone line. In addition, dial numbers such as speed dials and auto dials are registered in the memory of the terminal device, and when a predetermined speed reducing operation is performed,
The corresponding dial numbers are sequentially read out from the memory and sent to the telephone line as dial signals.

On the other hand, a general telephone such as a single telephone is connected to this terminal device, and when the terminal device detects off-hook and dial operation of this external telephone, it captures a telephone line and dials the captured telephone line. The dial signals based on are sequentially transmitted. After sending the dial signal, the external telephone is connected to the telephone line. In this way, the dial signals based on the operation of the external telephone are sequentially sent to the exchange side via the telephone line, so that the call of the other party is made, and the outside call of the external telephone is made by the response of the other party. When the external telephone is on-hook due to the end of the call, the terminal device detects this and releases the telephone line, and disconnects the external telephone and the telephone line.

[0004]

By the way, the speed dial memory or the like is provided on the terminal device side as described above.
The terminal device itself can make a speed dial call.
However, an external telephone connected to such a terminal device cannot perform speed dial transmission unless it has a speed dial memory. on the other hand,
When a phone that can be registered as a speed dial is connected as an external telephone, the same dial number registered in this speed dial memory is registered in the terminal device in duplicate, so the speed dial memory can be stored efficiently. Cannot be used. Therefore, it is an object of the present invention to enable an external telephone to access a speed dial registered in a terminal device to enable speed dial transmission.

[0005]

In order to solve such a problem, the present invention provides a detecting means for detecting a predetermined operation after an off-hook of an accommodated external telephone and a dial output from the external telephone after the predetermined operation. A receiving means for receiving the instruction signal and a transmitting means for selecting a telephone number corresponding to the received dial output instruction signal from the dial memory and transmitting it as a dial signal to the telephone line are provided. Also,
The loop forming means is provided for forming a loop between the telephone line and the external telephone after all dial signals have been transmitted to the telephone line by the transmitting means. Further, an abnormality message is sent to the external telephone when either the dial output instruction signal is not received by the receiving means or the telephone number corresponding to the received dial output instruction signal is not registered in the dial memory. A message sending means is provided. Further, the normal message sending means for sending a normal reception message to the external telephone when the dial output instruction signal is normally received by the receiving means is provided. In addition, after the normal message has been sent, a confirmation operation from the external telephone is detected and an automatic call is made. Further, the automatic transmission is performed after a lapse of a predetermined time after the transmission of the normal message is completed.

[0006]

When a predetermined operation after the off-hook of the accommodated external telephone is detected and a dial output instruction signal is received from the external telephone after the predetermined operation, the telephone number corresponding to the received dial output instruction signal is stored in the dial memory. It is selected from the inside and sent out to the telephone line captured as a dial signal. As a result, the external telephone can access the speed dial registered in the terminal device and perform speed dial transmission. Also, after all dial signals have been sent to the telephone line, a loop is formed between the telephone line and the external telephone. As a result, it is possible to prevent the dial output instruction signal or the like from being sent to the telephone line by operating the external telephone. Also,
An abnormal message is sent to the external telephone when either the dial output instruction signal is not received or the telephone number corresponding to the received dial output instruction signal is not registered in the dial memory. As a result, the user of the external telephone can accurately recognize that the speed dial transmission is impossible. When the dial output instruction signal is normally received, a reception normal message is sent to the external telephone. As a result, the user of the external telephone can accurately recognize that the speed dial is normally transmitted. After the normal message is sent, the confirmation operation from the external telephone is detected and the call is automatically sent. As a result, it is possible to prevent the call from being sent to a party different from the desired party. Also, automatic transmission is performed after a lapse of a predetermined time after the transmission of the normal message is completed.
As a result, the confirmation operation of the external telephone can be omitted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a terminal device to which the present invention is applied. In the figure, this terminal device 1A
Is a telephone device, which is connected to a telephone line (hereinafter, line) L and accommodates an external telephone 2 such as a single telephone. A CPU 11 is provided in the terminal device 11A,
The CPU 11 includes a ROM 12 that stores programs executed by the CPU 11, a RAM 13 that stores a plurality of dial numbers (telephone numbers), a timer / counter 14 that measures time, a line control unit 16, and an I / O unit 17 as a bus. BS
Are respectively connected via.

The line control unit 16 is connected to a call unit 21 such as a call circuit, and the call unit 21 is connected to a dial unit 22 for generating a dial signal or the like. Also, I
In addition to the above-mentioned call unit 21 and dial unit 22 being connected to the / O unit 17, an operation unit 18 such as a dial key, a voice synthesis unit 23 for generating a voice message, and an external device for controlling the external telephone 2. PB from telephone control unit 24 and external telephone 2
The PB detectors 25 that detect signals are connected to each other.

When the terminal device 1A thus constructed is off-hook, the CPU 11 detects a hook switch (not shown) and controls the line control unit 16 to capture the line L. Subsequently, when the CPU 11 inputs a dial number operated by the operation unit 18 via the I / O unit 17, the CPU 11 controls the dial unit 22 to generate a dial signal corresponding to the operated dial number. This dial signal is sent to the line L via the call unit 21 and the line control unit 16.
Sent to The dial numbers sequentially operated in this manner are transmitted as dial signals from the line L to the exchange side, so that the call of the other party is made. When the other party answers the call, the outside line call is made.

A plurality of dial numbers are registered in the RAM 13 of the terminal device 1A as described above. In this case, when the off-hook operation is performed and the speed dial operation is performed by the operation unit 18, the CPU 11 sequentially reads out the corresponding dial number in the RAM 13 and sends it to the dial unit 22, whereby the speed dial transmission can be performed. Also, C
When the PU 11 detects the off-hook of the external telephone 2 via the external telephone control unit 25 and the I / O unit 17, the PU 11 controls the line control unit 16 to similarly capture the line L. Subsequently, when a dial number based on the dial operation of the external telephone 2 is detected via the external telephone controller 24, the PB detector 25, and the I / O unit 17, this dial number is detected.
To generate a dial signal and send it to the line L.
After that, when the CPU 11 detects that the sending of the dial number from the external telephone 2 is completed, it controls the external telephone control unit 25 to connect the external telephone 2 and the line L accommodated in the line control unit 16. The connection is established and the external telephone 2 is transferred to an outside line call.

By the way, such an external telephone 2 cannot perform speed dial transmission unless speed dial is registered in itself. If you connect a telephone that can register speed dials as the external telephone 2,
Dial number registered in external telephone 2 and terminal device 1A
The speed dial memory cannot be used efficiently because the same dial number is registered as the dial number registered in. For this reason, the external telephone 2 accesses the speed dial registered in the terminal device 1A and enables speed dial transmission.

FIG. 3 is a flow chart showing the operation of the main part of the terminal device 1A, and shows an example in which the external telephone 2 accesses the speed dial in the terminal device 1A to make a speed dial call. In this case, the CPU 11 of the terminal device 1A
First, in step S1, it is determined whether the external telephone 2 goes off-hook. Then, when the off-hook of the external telephone 2 is detected, the external telephone 2 detects R in step S2.
It is determined whether or not the dial number registered in the AM 13 is used. In the present embodiment, whether or not the external telephone 2 is used for the speed dial is determined by whether or not the dial key "*" of the external telephone 2 is operated.

When the dial key "*" is operated on the external telephone 2 and is received, the CPU 11 determines "Y" for "use speed dial" in step S2. In this case, the CPU 11 subsequently performs a receiving operation of receiving the abbreviated number through the PB detection unit 25 by operating the dial key (numerical key) on the external telephone 2 side in step S3. It should be noted that this abbreviated number is a number (dial output instruction signal) for designating one of the registered dial numbers and is sent to the terminal device 1A side as a PB signal in this embodiment. .
In step S4, it is determined whether the abbreviated number received in step S3 is a normal number.

If the abbreviated number is normally received and the dialed number corresponding to this abbreviated number is registered in the RAM 13, the abbreviated number reception normal message is sent to the external telephone 2 in step S5. That is, in this case, C
The PU 11 drives the voice synthesizing unit 23 via the I / O unit 17 so that the voice synthesizing unit 23 makes a speed dial call based on the shortened number (for example, “telephone number of shortened number XX”).
A normal voice message "... will be automatically sent to ..." will be output, and the external telephone 2 will be sent via the external telephone controller 24.
To send to.

This voice message is heard by the user of the external telephone 2. As a result, when the user confirms that this telephone number is correct and performs a confirmation operation of, for example, the “#” key, the CPU 11 detects this confirmation operation via the external telephone control unit 24. . In this case CPU11
Controls the line control unit 16 to capture the line L, and
The dialed number corresponding to the received abbreviated number is sequentially read out, sent out to the dial unit 22, and the dialed dial process is executed in step S6 in which dial signals are sequentially sent out from the dial unit 22 to the capture line L. After the normal voice message is sent to the external telephone 2 side, the external telephone 2
If the confirmation operation from is not detected, the CPU 11 executes the speed dial transmission in step S6 after the timer / counter 14 measures a predetermined time.

Then, the process shifts to step S7, and it is determined whether or not the speed dial transmission process as described above is completed. At this point, the speed dial transmission is completed and "Y" is given in step S7.
Then, in step S8, the CPU 11 controls the external telephone control unit 25 to connect the external telephone 2 and the line L accommodated in the line control unit 16, and the line L and the external telephone 2 are connected.
The external telephone 2 is transferred to an outside line call by forming a loop with In this way, the external telephone 2 can make a speed dial call using the dial number registered in the RAM 13 in the terminal device 1A.

If the abbreviated number is not normally received from the external telephone 2 or if the dialed number corresponding to the abbreviated number is not registered in the RAM 13 even if the abbreviated number is normally received, the CPU 11 executes "S5" in step S5. It is determined that "the reception of the abbreviated number is normal" is "N". In this case, the CPU 11
Drives the voice synthesizing unit 23 in step S9, and outputs a voice message indicating an abnormal reception of the abbreviated number from the voice synthesizing unit 23 (for example, "the abbreviated number operated is abnormal" or "the abbreviated number operated is called A voice message such as "No number is registered" is output and sent to the external telephone 2 via the external telephone control unit 24.

Further, after the off-hook of the external telephone 2 is detected, the PB signal based on the depression of the dial key "*" is not detected from the external telephone 2 and the PB dial signal based on the other dial key operation is detected. If detected through the PB detection unit 25, the CPU 11 determines that “use speed dial” in step S2 is “N”. In this case, CPU1
1 is the sequentially detected dial number RA in step S10
Save in a separate area of M13. And the external telephone 2
Such a dial input from S is not detected for a certain period of time measured by the timer / counter 14, and step S
When the determination of 11 becomes "Y", the process proceeds to step S6.

In this case, the CPU 11 at step S6
The line controller 16 is controlled to capture the line L, and the RAM 13
By sequentially sending the dial numbers stored in the separate area to the dial unit 22, dial dialing is performed in which dial signals are sequentially sent from the dial unit 22 to the capture line L. After that, when the dial transmission is completed and the answer becomes “Y” in step S7, the external telephone 2 is connected to the line L accommodated in the line control unit 16 in step S8, and the external telephone 2 is connected to the outside telephone line. Move to. In this embodiment, the RAM 1 in the terminal device 1A is operated by the external telephone 2 operating the dial key "*".
Although the speed dial No. 3 is accessed, the dial key "#" may be operated, and any key can be operated as long as it can be distinguished from a normal dial key.
Further, although the external telephone 2 accesses the speed dial of the terminal device by the PB signal, the PB detection unit 25 is provided in the device.
If a DP (dial pulse) detector is provided instead of the above, it is possible to access by the DP signal.

Further, although the terminal device has been described as the telephone device in the present embodiment, the same effect can be obtained even when applied to a facsimile device. FIG. 2 is a block diagram showing an example in which the terminal device is a facsimile device.
Is a configuration in which a modem 15, a printing unit 19, and a reading unit 20 are added to the configuration of the terminal device 1A described above. That is, a modem 15 for transmitting and receiving image data and the like is provided between the CPU 11 and the line control unit 16, a printing unit 17 for recording the received image data on a recording paper, and a reading unit 20 for reading the image data from the original document, respectively. It is connected to the I / O unit 17 so that the CPU 11 can access each of these units. In this case, the CP of the terminal device 1B
As in the case of the terminal device 1A, the U11 sends the dial number by the operation of the operation unit 18 or the dial number read from the abbreviated dial area of the RAM 13 by a predetermined operation of the operation unit 18 to the dial unit 22 to make a line signal as a dial signal. Send to L and call the other party. Then, when the other party responds, a predetermined protocol is executed through the modem 15, and then the image data read by the reading unit 20 is sent to the modem 15 to be encoded and the line control unit 16
And the transmission to the other facsimile machine via the line L or the like.

Since the terminal device 1B can communicate with the other telephone in addition to performing facsimile communication,
In the speed dial area of the RAM 13, in addition to the speed dial number corresponding to the telephone number of the partner facsimile machine, the speed dial number corresponding to the telephone number of the partner telephone is also registered. Therefore, even in such a speed dial area in the terminal device 1B, the external telephone 2
Can access the terminal device 1A as in the case of the terminal device 1A and automatically send the dial number of the partner telephone registered in the area to the line L as a dial signal. Therefore, the external telephone 2 can make a dial call using the speed dial on the terminal device side without registering the speed dial.

[0022]

As described above, according to the present invention, a predetermined operation after the off-hook of the accommodated external telephone is detected,
Further, when a dial output instruction signal from the external telephone is received after this predetermined operation, the telephone number corresponding to the received dial output instruction signal is selected from the dial memory and sent as a dial signal to the captured telephone line. Therefore, the external telephone can access the speed dial registered in the terminal device and can perform speed dialing. Also,
After all dial signals have been sent to the telephone line, a loop is formed between the telephone line and the external telephone, so it is possible to send dial output instruction signals to the telephone line by operating the external telephone. It can be prevented. In addition, an abnormal message is sent to the external telephone when either the dial output instruction signal is not received or the telephone number corresponding to the received dial output instruction signal is not registered in the dial memory. The user of the external telephone can accurately recognize that speed dialing is impossible. Further, when the dial output instruction signal is normally received, the reception normal message is sent to the external telephone, so that the user of the external telephone can accurately recognize that the speed dial is normally transmitted. . Further, since the confirmation operation from the external telephone is detected and automatically transmitted after the completion of the transmission of the normal message, it is possible to prevent the transmission to a different party from the desired party. Further, since the automatic call is made after a lapse of a predetermined time after the sending of the normal message is completed, the confirmation operation of the external telephone can be omitted.
