Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone terminal, and more particularly to a telephone terminal which is connected to peripheral devices such as a display device and has various functions.

In recent years, telephone terminals have not only been used to simply exchange voice information, but have also been equipped with various functions (memory of the called party's telephone number, automatic dialing, etc.), and can be thought of as data processing devices connected to exchanges. can.

[Conventional technology]

As shown in FIG.
There is one that is connected to a computer (such as a personal computer) via an interface 2. The data processing device may include a CPU 3, a main storage device 4, a display device 5, a keyboard device 6, a printer device 8, an external storage device 7 (such as a floppy disk device), and a keyboard 6 connected via a bus. For example, by inputting data from the keyboard 6 on the screen of the display device 5, a list of telephone numbers of customers etc. is created and stored in the floppy disk device 7. It memorizes the screen contents of the display 5, etc. Then, a list is created of the data read from, for example, the floppy disk device 7, corresponding to the type of customer (destination). This telephone number list is read out from the floppy disk device 7,
It is stored in the main storage device 4 and displayed on the display device 5, and the CPU 3 encodes the displayed telephone number of the destination and sends it to the telephone via the interface 2, and on the telephone side, the code information of the transmitted telephone number is transmitted. It automatically converts it into dial information (dial pulse or push button signal) and sends it to the exchange. By adding such processing functions to telephones, even when the number of destinations to which dialing information is sent is extremely large, it is possible to connect to the destinations accurately, improving service. It can be measured.

[Problem that the invention seeks to solve]

However, the above-mentioned telephone terminal only has a function of simply sending out dial information. Therefore, if the called party was busy or absent, this could not be automatically detected, and the caller had to take note of whether the caller was busy or absent. The caller was then required to confirm this memo and send the dialing information again to correct the problem.

[Means for solving problems]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to automatically detect the response of the called party, thereby eliminating the need for the caller to take the trouble to check the caller's response, thereby further improving the service.

In order to achieve the above object, the present invention provides dialing in a telephone terminal connected to a first line whose polarity is inverted for sending billing information when the called party is off-hook or a second line whose polarity is constant. polarity reversal detection means for detecting a reversal of the polarity of the first line after sending out the information and outputting a detection signal; and counting means for outputting a detection signal when the off-hook state continues for a certain period of time after sending out the dial information. A response from the called side is detected by a detection signal from the polarity reversal detection means or the counting means.

(Function) According to the above configuration, the polarity of the first line, such as a public line, is reversed in order to send billing information in response to a response (off-hook) from the called party, so that the telephone terminal connected to this reverses the polarity of the first line such as a public line. A response from the called side can be detected by detecting the polarity reversal.

In addition, on the second line that connects the private branch exchange and the telephone terminal, if a certain period of time has elapsed since the calling party sent out the dial information, the receiving party responds and enters the talking state. (If the caller goes on-hook)
There is no response and a response from the called party is detected.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a detailed block diagram of the telephone body 1 shown in FIG. FIG. 2 is a diagram for explaining the operation of FIG. 1. The operation shown in FIG. 1 will be described below based on the processing flow shown in FIG. 2.

The CPU 11 via the interface 10
Receives the dial information of the called party from CPU3.

Upon receiving the dial information, the CPU 11 turns on the R relay and connects the R relay to the x side.

After receiving the dial information, the CPU 11 scans the inversion detection circuit 13, identifies whether the signal output from the inversion detection circuit 13 is "1" or "0", and sets this state in, for example, a register. .

Then, the CPU 11 sets the dial information received from the CPU 3 in the dial sending circuit 12. The dial sending circuit 12 outputs a dial pulse signal or a push button signal to the lines L ₁ and L ₂ based on the set information.

The function key 14 is a switch for setting whether the line to which the telephone main unit 1 is connected is a public line or a private branch exchange.
If the telephone is connected to a private branch exchange, it is set to "0". Therefore, by scanning the function key 14, the type of line to which the telephone main body 1 is connected can be identified.

By scanning the function key 14, it is determined whether the state is "0" or "1". If it is "1", the process moves to step 2, and if it is "0", the process moves to step .

The CPU 11 scans the inversion detection circuit 13,
Compare with the value set in the register during processing.

,' When an inversion is detected based on the comparison result, it is stored in the memory 15 corresponding to the dial information sent as a response from the called party. If it is not reversed, the on-hook detection circuit 16 is scanned, and the F relay (which is linked to the telephone switch of the communication circuit 17) is turned to the x side in the figure when it is on-hook, and to the y side in the figure when it is on-hook. ) to detect whether it has been picked up. If the call is on-hook, it is stored in the memory 15 corresponding to the dial information sent as there was no response from the called party. If this is not the case, proceed to the processing again.

When the function key 14 is in the "0" state, the CPU 11 sets the timer 18 and starts counting.

The on-hook detection circuit 16 is scanned in the same manner as in process ''. If an on-hook is detected, it is stored in the memory 15 corresponding to the dial information sent as no response. Proceed to the process if there is no on-hook.

The CPU 11 has a timer set for a certain period of time (for example, 5
It is determined whether or not the number of seconds has elapsed, and if it has elapsed, it is stored in the memory 15 corresponding to the dial information sent as a response from the called party. If the certain period of time has not elapsed, return to the process.

The response from the called party is detected in the manner described above.

Note that the R relay is normally tilted toward the y side, but upon reception of dial information from the interface 10, it tilts toward the x side. Then, the CPU 11 processes,
When the R relay is reached, the R relay is reset.
The dial key 20 and dial sending circuit 12 are connected.

Here, the information stored in the memory 15 is transferred to the data processing device A shown in FIG. 3 via the interface 10, and a flag is set corresponding to the dial information to indicate the presence or absence of an incoming call response.

Therefore, through the processing of the CPU 3, a list of non-responsive customers can be created and displayed on the screen of the display device 5.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to automatically detect the presence or absence of a response from the called party, so that the data processing device can manage customers who have not received a call, that is, whether they are absent or busy. can be expected to further improve service.
