Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic switchboard, and more specifically to an automatic switchboard that allows incoming calls from a telephone to a facsimile terminal.

(Prior Art) In recent years, the spread of facsimile has been remarkable, and facsimile communication networks have been provided and services have been implemented that allow facsimile services to be used over long distances at charges that are considerably lower than regular telephone charges.

For example, Osamu Murakami's "Facsimile New Communication Media"
(-Telecommunications Technology News, published March 1, 1980) describes the prior art in such facsimile communication.

FIG. 2 shows a relay system diagram when facsimile terminals 3A and 3B join a facsimile communication network, as an example of a connection between facsimile terminal devices in the prior art. As shown in the figure, the subscriber line exchange (Loc)
al5w1tch:LS) 9 accommodates facsimile terminals 3A and 3B via its network 50, and is connected via a trunk line to a trunk line electronic exchange (TS-FX) 7 having a facsimile communication function.

When transmitting an image signal from the facsimile terminal 3A to the facsimile terminal 3B using the facsimile communication network, the facsimile terminal 3A sends the subscriber number of the facsimile terminal 3B to the subscriber exchange 9 following the special number r161J for facsimile communication calls. Send. When the subscriber exchange 9 receives these signals, it detects the calling number and sends it to the trunk electronic exchange 7 together with the called number.

When the trunk line electronic exchange 7 receives the caller number and the called party number, it transmits a calling signal (1300 Hz) that activates the bell of the facsimile terminal 3B without ringing unless the facsimile terminal 3B is in communication. Facsimile terminal 3B
When it receives this calling signal, it sends a response signal (2100Hz
) will be returned. After information regarding the transmission control procedure is exchanged between the facsimile terminals 3^ and 3B,
The image signal of the message is transmitted from the facsimile terminal 3A to the facsimile terminal 3B.

The connection route between facsimile terminal 3^ and facsimile terminal 3B is facsimile terminal 3A - network 5.
- Trunk line electronic exchange 7 - Network 50 - Facsimile terminal 3B.

(Problem M to be Solved by the Invention) However, in such prior art, both the calling and receiving parties had to be facsimile terminals. That is, even if a subscriber subscribes to a facsimile communication network service, facsimile communication is impossible when the calling party is a telephone and the receiving party is a facsimile terminal. Therefore, in order to send a message using facsimile communication, the sender must also own a facsimile terminal as equipment.

This poses a problem in that it must be transmitted.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such drawbacks of the prior art and to provide an automatic switching system that can send messages even from a telephone to a facsimile terminal.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention receives a voice signal from a calling side type speaker, converts the voice signal into a signal suitable for a facsimile terminal, and transmits the signal to the facsimile terminal. The automatic switchboard has 1 voice recognition means that recognizes the voice signal sent from the calling machine and converts the voice signal into a signal that can be restored by the facsimile terminal, and a voice recognition means that sends the signal converted by the voice recognition means to the facsimile terminal. The facsimile terminal is equipped with modulation means for modulating a signal suitable for transmission, and when it receives a selection signal indicating a request for receiving a call from the calling side telephone to the facsimile terminal, it activates these means to receive the voice signal from the calling side telephone. Converts it into a signal that can be output on the side facsimile terminal.

(Function) When the automatic switching system according to the present invention receives a selection signal indicating a request for receiving a call to a facsimile terminal from a calling party's telephone, it connects the calling party's type telephone and the voice recognition means to detect the call from the calling party's telephone. The voice signal is converted into a signal that can be restored by the facsimile terminal, modulated by the modulation means, and transmitted to the facsimile terminal desired by the calling telephone.

(Example) Next, an example of an automatic exchange according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, there is shown a diagram of a relay system in an embodiment of an automatic switching system according to the present invention.

The subscriber line switch (LS) 5 accommodates multiple communication terminals and is a central control unit! The automatic exchange has the function of controlling these exchanges by means of a telephone 60 and, upon receiving a selection signal, for example rlXYJ, indicating an incoming call request from a housed telephone to a facsimile terminal, controls the incoming call. Here, x and y mean arbitrary numbers.

The subscriber line exchange 5 has a network 50 through which it is connected to a plurality of subscriber terminals or trunk lines. That is, the network 50 is connected to the telephone 1 via a subscriber line 100 and to the facsimile terminal 3 that is subscribed to a facsimile communication network via a subscriber line 102. The network 50 is also connected via a trunk line 110 to a trunk electronic switching system (TS-FX) 7 having a facsimile communication function. network 5
0 is further connected to the outgoing register trunk 52 via the signal line 200 and to the voice recognition bag via the signal line 202! ! At 54,
They are each connected to a modulation device 56 via a signal line 204.

The call register trunk 52 is a trunk that sends a dial tone to the off-hook subscriber terminal after completion of dial preparation. When the transmission register trunk 52 receives a selection signal from a subscriber terminal after transmitting a dial tone, it counts the selection signal,
The information is stored and sent to the central controller 60.

The voice ry,m device 54 is a device that recognizes a voice signal and converts the voice signal into a signal that can be restored by a facsimile terminal, and is activated when there is a request for an incoming call from a telephone to a facsimile terminal. That is, when the voice recognition device 54 receives an incoming call request to the facsimile terminal, it uses voice guidance to instruct the telephone that made the request to send a message to be sent to the facsimile terminal. Audio BWI equipment! f54 again. When a message to be sent from the telephone to the facsimile terminal is sent in the form of voice, this voice, which is an analog signal, is converted into a digital image signal, that is, a facsimile signal, which can be output by the receiving facsimile terminal, and is sent to the modulation device 56. . In this way, the voice recognition device 54 converts the voice signal into an electric signal of image information, and generates information equivalent to the electric signal by photoelectric conversion performed at a facsimile terminal.

The modulation device 56 is a voice recognition bag! ! This device has a built-in modem that converts the digital signal received from 54 into a signal suitable for transmission. Such conversion is called modulation, and examples of modulation techniques include amplitude modulation, frequency modulation, polyphase modulation, and quadrature amplitude modulation. Furthermore, in digital signal modulation, 4800 bit/s or 9600 bit/s in the case of digital image signal or encoded data transmission.
/s modem is used.

The transmitting section of the modem disposed in the modulation device Wt56 in this embodiment includes a circuit that randomizes transmission data into a form suitable for modulation, an orthogonal circuit that generates an amplitude phase modulation signal, and the like. Note that the transmission speed is selected from among the above, for example, as necessary. Since transmit or receive data is input to or output from such a modem, the modulator 56 is provided with control and timing signals for this data by a standard interface.

The control device 58 includes the voice recognition device 54 and the modulation device 56.
This is a control circuit that controls the In other words, when there is a communication request from the telephone to the facsimile terminal, the control unit! 58 is
The audio modulation device M54 is controlled via a control line 210, and the modulation device j5f5 is controlled via a control line 212, respectively.

The central control unit 60 is a device that processes each component of the subscriber line exchange 5 according to stored programs.

That is, the central controller 60 controls the originating register trunk 5.
2, when receiving the special number rlXYJ indicating an incoming call request from the telephone to the facsimile terminal, and further receiving the subscriber number of the called facsimile terminal, the voice recognition device 54
Controls the connection between the caller and the calling phone. Then, the subscriber numbers of the calling side telephone and called side facsimile are transmitted to the modulator 5.

Central control unit! 60 also controls the control device i5g to connect the calling party's telephone and the voice recognition bag when the facsimile communication is completed. ! 54, and sends a call to this telephone indicating that communication has ended.

In this figure, in order to facilitate understanding of this embodiment, each component of the subscriber line exchange 5 that is not directly related to this embodiment is omitted. Further, the relay system diagram shown in the figure is for explaining the present embodiment, and the present invention is not necessarily limited to this.

Next, the operation when sending a message from telephone 1 to facsimile terminal 3 will be explained.

After confirming the dial tone, when the special number rlXYJ is dialed from the originating telephone 1 as an incoming call request to the facsimile terminal, this selection signal is transmitted from the telephone 1 to the subscriber line exchange 5.
- Network 50 - 0 received at the calling register trunk 52 by the route of the calling register trunk 52 When the calling register trunk 52 receives the selection signal from the telephone 1, it transfers it to the central controller 60. Central control bag! ! 60 is.

When the special number rlXYJ is received, it is recognized that the call is an incoming request from the telephone to the facsimile terminal.

When the subscriber number of the receiving facsimile terminal 3 is dialed from the telephone 1 following the special number rlXYJ, this subscriber number is sent to the calling register trunk 5 via the same route.
2 and forwarded to the central controller 60. When the central control bag [60 confirms that the facsimile terminal 3 has received the subscriber number, it connects the telephone Ia1 and the voice recognition device 54 through the route of the telephone 1 - subscriber line exchange 5 - network 50 - voice recognition device 54. .

When the telephone 1 and the voice recognition bag [54 are connected, the voice recognition bag! ! 54 notifies the telephone 1 to send a message to be transmitted to the facsimile terminal 3 by voice guidance. This allows you to receive an e.g. message from Phone 1, ``My current location is...''
” is sent, the voice Btl & device 254 converts the content of the call from an analog signal to a digital signal, and transfers it to the modulation device 56 as image data. The central control unit 60 also detects the subscriber number of the telephone set 1 and sends this subscriber number together with the subscriber number of the facsimile terminal 3 to the trunk line electronic exchange 7 via the modulation device 56.

When the trunk line electronic exchange 7 receives the subscriber numbers of the telephone 1 and the facsimile terminal 3,
OC episode! ! (not shown).

A response signal of 2100 Hz is sent to the modulation device 56 to instruct facsimile transmission. When the trunk line electronic exchange 7 and the modulation device 56 are connected, communication control such as checking for terminal abnormalities and instructing the communication mode is performed.

The transmission control procedure for controlling communications is usually called a binary procedure and has been standardized by the CCI Recommendations. In other words, for example, 300 bits are required for transmitting the control signal.
, and the I(nlLC frame structure is used.

If the receiving facsimile terminal 3 is not busy, a facsimile ringing signal (130
0Hz) is transmitted. When the facsimile terminal 3 returns a response signal, the modulation bag 5t56 and this terminal 3 are connected, and after communication control, an image signal, which is a facsimile signal, is modulated and sent from the modulation bag [56].

When the facsimile terminal 3 receives this image signal, it prints it out in the form of one message. The content of the message is ``My current location is...'' sent by voice from telephone 1, and the connection route at this time is modulator 56 - network 50 - subscriber line exchange 3 - Trunk line electronic exchange 7
- subscriber line exchange 5 - network 50 - facsimile terminal 3.

The audio content of the telephone 1 is delivered to the facsimile terminal 3,
When the communication is finished, the control device 58 and the central control device 5
0 is a phone I11 and a voice recognition bag! 54. The central control unit 60 then connects the telephone 1 to a talk trunk (not shown) and sends a talk tone to the telephone 1 indicating that delivery of the message has been completed.

Further, if the facsimile terminal 3 is busy, facsimile communication cannot be performed, so it is necessary to notify the telephone 1 that the message has not been delivered.

In this case, the telephone 1 is connected to a busy trunk (not shown) and a busy tone is transmitted.

Although this embodiment has been described with respect to the facsimile terminal 3 that has joined the facsimile communication network, the present invention is of course not limited to this, and the facsimile terminal does not need to have joined the facsimile communication network. Furthermore, although this embodiment has been described for communication within the area, it is also applicable to communication outside the area.

Further, in this embodiment, the subscriber line exchange 5 has been described as an example, but the subscriber line exchange 5 may be replaced by, for example, a private branch exchange or the main device of a key telephone system.

(Effects of the Invention) As described above, according to the present invention, a facsimile message can be sent to a facsimile terminal on the called side without connecting a facsimile terminal on the calling side.

Therefore, it is possible to reliably notify the called party even if the content is difficult to communicate over the telephone. Furthermore, by using a facsimile terminal, necessary matters can be accurately sent as a facsimile message, so the call time can be shortened compared to telephone contact.

Furthermore, it is not only unnecessary to take notes on the receiving side, but also prevents mistakes in listening or forgetting to take notes.
