[Industrial Application Field] The present invention relates to a method for notifying numerical information in a digital exchange that notifies a voice terminal of the digital exchange of numerical information held by the exchange.

2. Description of the Related Art In recent years, digital exchanges have become widespread, and as a result, multifunctional digital terminals equipped with display functions and the like are being installed as telephone terminals. However, since digital terminals are expensive and the cost of the exchange system is high, conventional voice (analog) terminals are often used (in that case, of course, A/D converters and D/A converters are used). .

To the subscriber in such a digital exchange,
A variety of services are provided, and among them are services such as wake-up calls and call forwarding, in which registered information selected by the user, such as registered time and forwarding destination telephone number, is held in the exchange.

If such registration information is clearly a numerical value inappropriate for time information, or if it is a non-existent forwarding destination phone number, it is possible for the exchange to detect an error, but if the registration information of other users It is impossible for the switch to detect the error. For this reason, methods for confirming registered content include a function that digitally transmits numerical information and displays the registered content on a terminal with a display, and a function that notifies the user using a voice guidance device, etc.
However, if such a function is provided, both the terminal and the switching equipment become expensive and it is often difficult to adopt them.Therefore, it is necessary to provide a means of notification of registered contents from the switching equipment that does not have audio guidance etc. even for terminals that do not have a display display. is desired.

[Conventional technology] FIG. 8 shows an explanatory diagram of a conventional example.

A in FIG. 8 shows the first conventional example, in which 80 is a terminal with a display, 81 is a communication path section of a digital exchange, and 82 is a control section.

This conventional example 1 uses a terminal 8 with a display as a terminal.
This is an example of using 0, and the control fi1 section 8 can be controlled by registering various services from the display terminal 80.
Registration data is stored in the registration data storage section 1321 of No. 2. When the user performs an operation to request display of registered contents from the same terminal 80, the display control unit 822 of the control unit 82
When display data is created based on the registered data and sent to the terminal, the registered data is displayed on the display of the terminal 80, and the user can check this.

Next, FIG. 8B shows conventional example 2, in which 81 is a communication path section, 82 is a control section, 82 is the same as in A above, and 8
3 is a voice terminal without a display, and 84 is a voice guidance device.

This conventional example 2 is an example in which the exchange is equipped with voice guidance, and when the user performs registration and requests the display of the registered contents on the terminal 83, the communication path unit 8 of the exchange
1 is controlled and the line of the terminal 83 and the voice guidance device 8
Connect 4. Next, voice guidance control section 1 ] 23
extracts the registration data stored in the registration data storage section 821 and supplies the numerical value to the voice guidance device 84 according to the determined interface conditions. The voice guidance device 84 performs voice synthesis etc. based on the contents of the supplied registration data, and notifies the terminal 83 by voice via the connected bus.

[Problems to be Solved by the Invention] As described above, the conventional method of notifying numerical information has the problem of requiring a terminal with a display function and expensive equipment such as a voice guidance device. .

In addition, if these devices are not provided, it may be impossible to provide services that require confirmation of registered contents, or even if services are provided, the services must be performed without a confirmation function, and the terminal There is a problem in that it causes inconvenience and anxiety to users.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for notifying numeric information in a digital exchange that can economically notify numeric information without installing expensive equipment in terminals and the main body of the exchange.

[Means to solve the problem] FIG. 1 shows a basic configuration diagram of the present invention.

In Figure 1, 10 is a voice terminal, 11 is a digital exchange, 1
2 is a communication path unit, 13 is a communication path control unit, 14 is a memory, 1
5 is a digital (PCM) signal representing a constant audio frequency signal.
Reference numeral 16 represents a continuous signal sound source that generates a signal (16), and a silence signal sound source that similarly generates a digital signal representing silence.

The present invention patternizes and serializes registered data using a numerical pattern table, and switches and connects two sound sources, a continuous signal sound source and a silent signal sound source, to the audio terminal path according to the pattern, thereby producing an audible sound from the continuous signal sound source. The number is generated by changing the combination of lengths for each digit, and the number is notified to the subscriber of the voice terminal.

[Operation] FIG. 2 shows an example of a numerical pattern, FIG. 3 shows an example of patterning and serialization of numerical information, and FIG. 4 shows a sequence of path switching control for transmitting numerical information.

It is assumed that numerical information (for example, wake-up call time) registered by the user's voice terminal 10 is stored in the registered data storage section 141 of the memory 14 in FIG. When the user of the voice terminal 10 issues a registration display request to confirm the contents of the registered data, the numeric signal sound control means 131 in the communication path side JN unit 13 is activated, and the corresponding data in the registered data in the memory 14 is activated. At the same time, using the number pattern table 142 in the same memory 14, the registered data is patterned and serialized.

In the example of number patterning information shown in FIG.
” is represented by - short sounds (time Ts), the number “2” is represented by two short sounds separated by an interval (time Ta), and the number “5” is a long sound (time TI!,) is represented by - pieces. Also, the number °゛6''° is a pattern of consecutive long sounds and single sounds with a gap in between, and the number "0" is a pattern of two consecutive long sounds. .

As shown in Fig. 3, when serializing numerical information, the interval between digits is longer than a certain level (time Tb) in order to distinguish between digits.
will be established.

After patterning and serialization in this manner, the numerical signal tone control means 13.1 uses the timing generating means 132 to connect the terminals of the voice terminal 10 of the communication path section 12 to the terminals of the continuous signal tone source 15 according to the pattern. Switching control is performed to connect to either the path P1 to be connected or the path P2 to be connected to the terminal of the silent signal sound source 16. In this case, the pattern “rl
When the signal is at "L" level (periods of short and long sounds in Figures 2 and 3), it is connected to the continuous signal sound source 15.
3) is connected to the silence signal sound source 16.

Figure 4 shows the numbers “0”, 7°°, and “3”.

A control sequence for path switching by the numerical signal tone control means 131 in the case of notifying a four-digit number of "0°" is shown.In this, each timing Tl, Ts, Ta, and Tb is This is done using the timing generation means 132 in the.

The user who made the registration number display request listens to the intermittent audible signal sound and prepares a table showing the correspondence between the intermittent graph and numerical values in advance at the installation location of the terminal.
Be able to identify the meaning of the number patterns sent from the exchange.

[Example] FIG. 5 shows a configuration diagram of an embodiment of the present invention.

In FIG. 5, 50a and 50b are subscriber circuits, 51 is a multiplexing circuit (indicated by MPX), and 52 is a speech path memory (
53 is a demultiplexing circuit (represented by DMPX), 54 is a continuous signal tone generation circuit, 55 is a silent signal tone generation circuit, 56 is a line processor, 57 is a control memory (C
58 is a counter, 59 is a central control unit, 6
o represents a memory (indicated by MM), and 61 represents a PB receiver (indicated by PBR) which receives a two-frequency signal dial from an audio terminal.

The memory 60 in FIG. 5 is provided with a registration table 601 and a number pattern 602.Only two audio terminals A and B are shown in the 0MPX 31 as the memory 60 shown in FIG. 5, and other audio terminals and digital terminals (not shown) are accommodated. The audio terminal is subjected to A/D conversion and D/A conversion in the subscriber circuits 50a and 50b, and is multiplexed with the digital outputs of the continuous signal tone generation circuit 54, silent signal tone generation circuit 55, etc. in the MPX5I, and is transmitted on the highway. The signal is input to the SPM 52 via the

In the SPM52, under the control of the CM57, the signal of each channel is controlled to be written to the address of the SPM52 instructed by the CC59.The counter 58 is a counter that counts up sequentially, and the address is designated by its output and the contents of Sl) M52 are written. are read out in order, the read outputs are converted to a different channel than when manually operated, and when demultiplexed in the 0MPX53, each output becomes a digital output to be sent to the other party's terminal.
The output sent to B is sent to the subscriber circuit 5 via the routes shown in ■ and ■.
0a and 0b, respectively, and are D/A converted and transmitted to the audio terminal.

A processing flow diagram of the embodiment shown in FIG. 5 is shown in FIG. 6. FIG. 6 is a flow diagram for notifying the registration time of a wake-up call.

The registration process for a wake-up call is as publicly known, and terminal A dials the access special number for registering a wake-up call and then dials the registration time to receive MM6.
As is well known, the 0 display request code stored in the 0 registration table 601 dials the access special number for requesting a wake-up call display. If terminal A is a DP terminal, that special number is received by LPR56, and if terminal A is a PB terminal, it is received by MPX.
51, SPM52.0MPX53 via L"i'PBR6
1 is received. When this special number is received, a program which is a numerical signal tone control means of CC59 is activated.

The processing flow is shown in Figure 6. When a wake-up call display request is detected from a terminal, the wake-up call registration data (time information) corresponding to the request terminal is displayed.
(Figure 6, 63).

The registration table 601 extracted from the MM 60 is patterned and serialized using the same number pattern 602 of the MM 60 (64).

According to the result, the CC59 controls the CM57 to switch the output channel of the continuous signal tone generation circuit 54 and the output channel of the silent signal tone generation circuit 55 to the channel assigned to the terminal person. (65) In this way, the digital signal output from the 0MPX 53 to the receiving terminal of the terminal becomes numerical information expressed by the length of the audible signal tone.

When the sending of the numerical information is finished, this display service ends.

FIG. 7 shows an explanatory diagram of various inter-digit discrimination methods.

The first A represents the space between digits of a number by a silent interval of a predetermined length, and this method is as shown in Figure 3. (a frequency different from the frequency of the audible signal tone used for numerical information) is generated for a short period of time.

Furthermore, the method shown in C3 is performed by dialing the received digits each time a piece of numeric information is received at the receiving terminal. It is possible to adopt a configuration in which a mechanism is provided to receive the data and compare it with the numerical data sent immediately before, and if there is an error, the data is sent again.

[Effects of the Invention] According to the present invention, a display device is not required in the terminal;
In addition, there is no need for a voice guidance device in the switchboard itself.
Since numerical information can be notified to the terminal, it is possible to economically improve services for the terminal in registration services and the like.
