Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Noakun-IJ communication system that provides means for transmitting incoming facsimile information to a recipient and efficiently realizes shared use of facsimile.

BACKGROUND OF THE INVENTION As the information society progresses, facsimile communication networks are expected to become more widespread in the future, having a facsimile information storage function and high-speed transmission function. The facsimile machines accommodated in this communication network are equipped with a silent ring signal (
The bell will not ring with a ringing signal of a higher frequency different from the 16Hz ringing signal of the telephone. ), it is an effective system with the advantage that there is no restriction on the recipient when receiving a call, unlike a telephone.

However, facsimile machines are complex, including a scanning circuit for reading originals, a control circuit for terminal and transmission control, a modulation/demodulation circuit for signal transmission, and a recording circuit for recording, and it will take time to make them as economical as telephones. For this reason, the most common mode of use of facsimile machines is a shared use mode in which a single facsimile machine is used by a plurality of people.

For example, in a business office, there is one department room or one floor.
A method has been adopted in which a facsimile machine is installed and used jointly. However, when a facsimile machine receives a call reception request due to its automatic call reception function, the same facsimile machine receives a plurality of transmission documents from an unspecified number of senders.

In such cases, in order to ensure that the sender sends the manuscript to the other party, the sender should inform the recipient in advance that the manuscript will be sent by phone or fax before sending the manuscript, or When the facsimile transmission is complete, the receiver calls the recipient to inform them that the document has been sent, and then returns the facsimile to the recipient.
In 1, Uke had to tell him to go pick it up.

On the other hand, on the recipient side, it was necessary to periodically check whether the received document was received by facsimile.

In this way, in the form of shared use of facsimile,
In order to ensure that the recipient receives the specified manuscript, the two procedures described above are required, and the procedure for selecting the specified manuscript from among the multiple manuscripts received from an unspecified number of senders. The disadvantage was that administrative processes were not streamlined.

FIG. 1 shows an example of the configuration of a communication network used for conventional facsimile communication, in which 1 and 2 are relay electronic exchanges having a factor 41J communication function that performs subscriber file verification, silent ring signal control, etc.; 3. 3', 4, and 4' are subscriber line exchanges or trunk line exchanges having calling number detection and transfer functions and 7% connection functions; 5 and 6 are storage and conversion devices that perform image signal storage and conversion processing; and 7 is a control signal. and transmission lines for high-speed transmission of image signals, 8 and 9 are telephones 8a18b, respectively.

・Consists of 9y, lO and 11 are factors of 41
J device, 12a and 12b indicated by broken lines are areas where facsimile machines 1o and 11 are used.

In such a facsimile usage mode, for example, when a subscriber of telephone 8a sends a document to a subscriber of telephone 9a using facsimile attachment 10, the communication network is connected to originating exchange 3. 1. The facsimile machine 11 is activated by a silent ringing signal via the originating side storage/converting device 5, the transmission line 7, the destination side storing/converting device 6, and the destination exchange 2.4, and the document is automatically sent. In this case, as mentioned above, the telephone 8
In order to ensure that subscriber a sends the manuscript to the subscriber using telephone 9a, it is necessary to separately notify the subscriber by telephone or the like that the manuscript has been sent.

In order to solve these shortcomings, the present invention adds the telephone number of the recipient to the telephone number of the incoming facsimile machine on the sending side, and when the document is sent to the receiving facsimile machine, the recipient receives the telephone number of the recipient. A facsimile incoming information detecting device connected in parallel to the telephone is activated by a silent ringing signal, and the facsimile incoming information is notified to the receiver.

FIG. 2 shows a diagram of an embodiment of the communication network configuration according to the present invention, and FIG. 3 is a diagram showing an example of an operation flow for explaining the operation of the communication network.

In Figure 2, 13 and 14 are 7ac 7mm incoming information Yokota equipment 13a + 13b + 13c and 14a
r Consisting of 14b and 14c, 15 is a number processing device that identifies the called number and the receiving number, 16 is a facsimile incoming information detection device that activates the facsimile incoming information detection device with a silent ring signal according to the recipient number, etc. The portion shown in FIG. 1 is the same as that shown in FIG.

The present invention shown in FIG. 2 will be described in detail below with reference to FIG.

The caller dials the special number for connection to the communication network for facsimile IJ communication, the incoming facsimile, the receiving device number of the IJ device, and the recipient number of the incoming facsimile device, which is a different telephone number. This dial signal is transmitted to exchange l via exchange 3 (or 3'). In the exchange 1, the number processing device 5 identifies the terminating device number and the recipient number, and sends a subscriber verification signal to the exchange 2 that accommodates the terminating facsimile device through a common line signal path, etc., and detects the terminating device number. Subscriber verification is performed to check whether a corresponding facsimile machine is accommodated or whether there is a recipient number in the same area as the receiving device number.

At this time, when the verification is completed, the exchange 1 receives a verification completion signal from the exchange 2 and sends a transmission instruction signal to the originating facsimile machine 10. When the originating facsimile device 10 receives the transmission instruction signal, it transmits a hook-and-spot image signal to the originating storage/conversion device 5 having an image signal accumulation function. Is the originating storage conversion device 5 temporarily turned off? Accumulates the image signal and transmits the transmission line 7
When the facsimile image signal becomes empty, the facsimile image signal is transferred to the destination storage/conversion device 6. The destination storage/conversion device 6 sends a transfer completion signal to the exchange 2 when the transfer of the facsimile image signal is completed.

The exchange 2 activates the destination facsimile device 11 with a silent ring signal via the exchange 4 in accordance with the destination device number. The destination facsimile machine 11 detects the silent ring signal and sends out a response signal. When the exchange 2 detects a response from the destination facsimile device, the exchange 2 transmits the response from the destination facsimile device 6.
A receivable signal is sent to the destination facsimile machine to notify that it is receivable. Therefore, the destination storage/conversion bag device 6 sends the facsimile image signal to the destination facsimile device 11, and ends the transmission of the facsimile image signal.

Next, the destination storage/conversion device 6 sends a transmission completion signal to the exchange 2 after completing the transmission of the facsimile image signal. The exchange 2 transfers incoming call information according to the recipient's number to the corresponding device in the incoming call information detecting device 14 connected in parallel to the recipient's telephone 9 using a non-ringing signal. For example, start 14a.

When the facsimile incoming information detection device i4a detects the non-ringing output signal, it returns a response signal via the exchange 4 by closing a DC loop or the like. The exchange 2 ends the facsimile communication when it detects the response signal.

In this way, in the configuration example of the communication network for realizing the present invention shown in FIG. The incoming facsimile information detecting device 13 and I4 are attached to the incoming facsimile signal, and the originating exchange has a function to identify the recipient number in addition to the special number and the incoming device number. This is realized by notifying the incoming facsimile information to the facsimile incoming information detection device according to the above-mentioned recipient number. Note that the facsimile incoming information may be transmitted when the facsimile machine starts receiving the facsimile, or when the facsimile reception ends, the same effect can be obtained.

FIG. 4 is a circuit diagram showing the configuration of an embodiment of the incoming call information detecting device used in the present invention, in which 17a and 17b are connection terminals to a telephone line, 18 is a telephone set, 19 is a signal detection circuit, and 2o
is a holding circuit, 21 is a power holding circuit, 22 is a switch, 2
3 is a display circuit.

This device uses a signal detection circuit 19 connected in parallel with the line and telephone 18 to detect a predetermined frequency of a silent ring signal received from the facsimile incoming information detection device 16 via the exchange 4 according to the recipient number. Detects received signal level and signal duration. As a result, if the detection state is reached, the holding circuit 20 is activated, and the display circuit 23 composed of an LED lamp or the like is activated to perform lighting display. At this time, the DC loop is closed by the signal detection circuit 19 as a response signal to the exchanges 2 and 4. The switch 22 is the display circuit 23.
Since the display is held once the non-ringing call signal is detected, the operator uses it when canceling the holding circuit 2o, and it is also used to turn off the display. The power supply circuit 21 is a circuit that supplies power to various parts.

FIG. 5 is a block diagram showing the configuration of one embodiment of the number processing device 15 provided in the originating exchange l used in the present invention.

The dotted lines (1) to (2) in the originating exchange 1 indicate the connections between the subscriber line 24 and each circuit constituting the number processing device 15 in the order of operation explanation.

First, as shown in ■, the subscriber line 24 is
When a caller makes a call, a DC loop of the subscriber line is formed, and the hook-off detection circuit 25 detects the caller's call. This detection output is sent to the control circuit 26. When the control circuit 26 detects the calling state of the caller, it starts up the exchange 1, connects the subscriber line 24 and the special number detection circuit 27 as shown in (3), and connects it to the communication network for Fakunmi IJ communication. Detects the special number. The special number is composed of, for example, IXY (X, Y are numbers from 0 to 9), and is input to the special number detection circuit 27 according to the PB multiple signal. When the control circuit 26 detects the special number, the control circuit 26 connects the subscriber line 24 and the terminating device number detection circuit 28 as shown in (2) in order to detect the terminating device number to be sent next.

The terminating device number is composed of an area number, a local number, and a subscription number, and is detected by the PB double signal by the terminating device number detection circuit 28.
is input. When the control circuit 26 detects the receiving device number, the control circuit 26 connects the subscriber line 24 and the recipient number detection circuit 29 as shown in (3) to detect the subsequent recipient number.

In the case of PB double signal using a bush button telephone to identify the incoming device number and recipient number, press the red button (low group frequency 941 Hz, high group frequency 1209 Hz) or the blue button (low group frequency 941 Hz, high group frequency 14
The circuit can be simplified by transmitting the PB multiplied signal (47 Hz) and transmitting the recipient number. If the recipient number is not detected, the document is simply sent to the destination facsimile machine.

Considering the form of shared use of facsimile, the recipient number is 4 because the toll number and local number are usually the same in order to transfer the incoming facsimile IJ information to the recipient who is close to the destination facsimile machine. The digit subscription number is input using the PB double signal. When the control circuit 26 detects the receiving device number, the control circuit 26 sends each number to the upper converter etc. via the common signal line 30, selects a route, connects the line, and sends the receiving party number to the receiving exchange. . On the other hand, when these operations are completed, the subscriber line 24 is connected to the line switching instruction signal sending circuit 31 as shown in (3), and the caller is prompted to switch from the telephone to the facsimile machine.

Thereafter, as shown in (3), the subscriber line 24 and the facsimile signal input circuit 32 are connected, and facsimile image information is input. This image information is transmitted via the signal line 33 to the receiving facsimile device via the storage/converting device and switching machine in accordance with the receiving device number.

FIG. 6 is a block diagram showing the configuration of one embodiment of the facsimile incoming information detection device 16 provided in the destination exchange 2 used in the present invention. When the receiving device number is input to the control circuit 35 via the common signal line 34, the exchange 2 is activated.
As shown in FIG. 3, the subscriber line connected to the facsimile IJ device 11 and the silent ring signal sending circuit 36 are connected. The silent ringing signal sending circuit 36 activates the facsimile machine 11 with a ringing signal of a frequency that does not ring the bell of the telephone 9 connected in parallel with the facsimile machine 11.

After the control circuit 35 sends out the no-ring ring signal for a certain period of time, the control circuit 35
It controls the exchange 2 and connects the subscriber line 24 and the response signal detection circuit 37 as shown in (3). Response signal detection circuit 37
detects a DC loop sent out when the destination facsimile device 11 is ready for reception, a single frequency signal indicating that the facsimile is connected, and the like. When the response signal detection circuit 37 confirms the connection with the facsimile device 11, the control circuit 35 activates the exchange and connects the subscriber line 24 and the facsimile signal output circuit 38 as shown in (3).

The facsimile IJ information is input from the storage/exchange device to the facsimile signal output circuit 38 via the signal line 39, and after being matched with the facsimile device, the image information is sent to the 7mm device. When this facsimile reception operation is completed, the control circuit 35 starts up the switching device again, and the facsimile incoming information detection device 14 connects as shown in (2) according to the recipient number sent from the originating switching device. The subscriber line and the silent ring signal sending circuit 36 are connected to each other.

The non-ringing call signal sending circuit 36 sends out a non-ringing ejection signal for a certain period of time, and activates the facsimile IJ incoming call information detection device 14. When the facsimile incoming information detection device 14 detects the silent ring signal, it performs a display such as lighting a lamp to notify the recipient that the facsimile document has been received. Further, the control circuit 35° connects the subscriber line 24 corresponding to the recipient number and the response signal detection circuit 37 as shown in (3). After the facsimile incoming information detection device 14 detects the silent ringing signal, the response signal detection circuit 37 detects a response signal such as a direct current loop to be sent, and the facsimile communication is terminated.

Further, the present invention can be easily applied to a private branch exchange system such as a PBX. That is, the private branch exchange connected to the telephone line is connected to the destination facsimile device within the private branch exchange using the destination device number, and performs a facsimile reception operation.

At this time, the originating facsimile machine inserts the recipient number into the facsimile control signal, etc., and transmits the recipient information to the private branch exchange or the destination facsimile machine. The private branch exchange detects the recipient number. According to this recipient number, when receiving facsimile information starts or ends, a facsimile receiving device transfer device consisting of a silent ring signal oscillator installed in the private branch exchange transmits the facsimile information to a facsimile terminal connected in parallel with the facsimile recipient's telephone. The IJ incoming call information detection device is activated by a silent ring signal. As a result, the facsimile incoming information detection device automatically displays and transmits the 7mm incoming information to the recipient. Therefore, facsimile incoming information can be easily transmitted to the facsimile recipient.

As described above, the present invention has an advantage in that it can improve the convenience of shared use of facsimile by automatically transmitting incoming facsimile information to the recipient. In addition, since the incoming call information is transmitted using a silent ring signal, there is no restriction on the recipient.Moreover, it is well suited for communication networks that have a storage and conversion function for conventional facsimile communication. It has the advantage of being able to provide exactly the same services as the above.
