Description

How the fax machine notifies the sending station of the reception result {METHOD FOR IMFORMING TO CALLCR RECEOVED RESULT INFORMATIOM IN A FACSIMILE DEVICE}

The present invention relates to a reception result notification method in a facsimile apparatus, and more particularly, to a reception result notification method for notifying a transmitting station of a result received in a fax.

Normally, the procedure for sending a document on an original from a facsimile is done by CCITT T.30. According to the procedure of CCITT T.30, the facsimile transmits and receives the protocol as shown in FIG. 1 in order to send and receive image data of the original by calling the receiving end. First, when the calling party calls the relative fax, the calling party sends a calling tone (CNG) signal to the receiving party. After receiving the CNG signal, the receiver transmits a Called Station Identification (CED) signal, and then transmits Non-Standard Facilities (NSF), Called Subscriber Identification (CSI), and Digital Identification Signal (DIS) signals. Then, the transmitting side transmits a non-standard set up (NSS), a transmitting subscriber identification (TSI) and a digital command signal (DCS) signal, and then transmits a training check (TPF) signal to the receiving side. The receiving side then sends a CFR (Confirmation To Receive) signal to the transmitting side. The transmitting side transmits original image data to the receiving side in response to the CFR signal. At this time, when one page of image data is transmitted, an EOP (End of Page) signal is transmitted from a transmitter to a receiver. Then, the receiving side transmits MCF (Message Confirmation) signal in response to the EOP to the sending side, and transmission and reception of one page of image data is terminated.In order to send and receive the next page, the sending side transmits the image data of the next page to the MPS. After transmitting the (Mutipage Signal) signal to the receiving side, the above-described operation is repeated to transmit the DCN (Disconnect) signal to the receiving side when transmission and reception are terminated. The document is transmitted and received by the above protocol. When a document is sent from the sending station by the above procedure, MCF and RTP (Retrain Positive), which are response signals from the receiving station, are sent in the POST MESSAGE step of the PHASE-D step. Receiving command of RTN (Retrain Negative), PIP (Procedure Interrupt Negative), PIN (Procedure Interrupt Negative), the sending station handles the transmission result as normal, but the sender can request a call if it needs to confirm. If the receiving station did not answer, voice call was impossible and the reception result could not be confirmed.

In addition, when the transmission is normally performed, the transmitting side performs the confirmation tone (CONFIRM TONE) processing and transmits the result to the LCD display only for a very short time. Therefore, when the surrounding environment is not quiet or far from the facsimile apparatus, there is a problem that often does not recognize the confirmation tone (COMFIRM TONE) and the error tone (ERROR TONE).

Accordingly, an object of the present invention is to provide a method for notifying a transmitting station whether a reception result of a document is received by a receiving station when the reception of a document sent from a transmitting station is terminated in a facsimile apparatus.

It is another object of the present invention to provide a method for notifying normal / error tone information of notifying a reception result to a transmitting station when receiving a document in a facsimile.

In order to achieve the above object, the present invention is characterized in that the image data is received while the protocol is in progress during ring reception, and when the image data reception is completed, the receiving station detects an error rate and transmits the reception result information to the transmitting station. do.

2 is a block diagram of a facsimile apparatus according to an embodiment of the present invention.

The central processing unit 10 controls the overall operation of the facsimile according to the set program, and transmits normal / error tone information upon completion of document reception. The memory 12 is composed of a ROM and a RAM, and stores a program and data. The ROM stores a program of the present invention, and a RAM stores data transmitted and received during communication. OPE 14 consists of a key input section and a display section. The key input unit of the OPE 14 allows the user to designate each mode and generate data of the dial key and output the data to the CPU 10. In addition, the display unit of the OPE 14 performs a function of inputting and displaying display data indicating an operation state of the system when the CPU 10 performs each mode. The scanner 16 moves an input document, scans an image of the document, and converts the image into digital data. The printer 18 prints the image data received during the reception mode and the copy mode or the image data scanned from the scanner 16 on a print sheet under the control of the CPU 10. The modem 20 modulates and transmits an image signal of a transmission type in a transmission mode under the control of the central processing unit 10, demodulates and receives an image signal input in a reception mode. A ring back tone, a busy tone, and a DTMF signal input through the line and LIU 22 are detected and transmitted to the CPU 10. A line interface unit (LIU) 22 forms a transmission / reception path between a telephone line (tip, ring) and a modem 20 under the control of the CPU 10.

4 is a control flowchart for notifying a transmitting station of reception result information at the end of document reception according to an embodiment of the present invention.

1 to 4, the operation of the preferred embodiment of the present invention will be described in detail.

In order to implement the present invention, the reception result response bits corresponding to the information bits of the NSF, NCC, and NSS commands, which are non-standard signals capable of responding to the reception result request at transmission, are set. However, the requirements are limited to models manufactured and sold by Samsung Electronics. The reason is that it is not the CCITT T.30 standard, so it is not compatible with other products. The operation of notifying the reception result information at the end of document reception after setting the request response enable bit in the reception result as described above is described with reference to the flowchart of FIG. 4. If ring receipt is detected by checking whether it is detected, proceed to step 102 and enter the document receiving mode to perform the protocol. At this time, it operates NSF + CSI + DIS command when operated in receive mode. Set the information bit in which the reception result request response is set in the NSF information and send it to the transmitting station. The sending station then sends an instruction of NSC + TSI + DCS. An information bit requesting a reception result request response in the NSC information is set in the FUNCTION PARAMETER of the non-standard command frame structure as shown in FIG. And when sending the TCF information for training to check the line condition, the receiving station sends the response signal CFR. The transmitting station then transmits the coded image data to be actually transmitted. In step 103, image data is received. Then, when the last original transmission is sent by the transmitting station, when the EOP command, which is a post message (POST MESSAGE), is sent, it is checked in step 104 whether the EOP signal is received. In step 105, it is checked whether the error rate is less than 10%. If the error rate is less than 10%, the flow proceeds to step 106 and a PIP command is sent to the transmitting station. However, if the error rate is 10% or more, the flow proceeds to step 107 to issue a PIN command to the transmitting station. At this time, when the answering station hooks off the telephone, the PRI-EOP signal is sent to the receiving station. Then, the receiving station recognizes the PRI-EOP signal and makes a telephone call to the transmitting station. If the reception result is normal, the receiving station transmits a tone signal having an on / off period for 1 second to the transmitting station for 10 seconds. However, in case of an error, the tone signal of 0.5 second on / off period is transmitted to the transmitting station for 10 seconds. The receiving station then turns off the line after the dispensing time has elapsed. The transmitting station then turns off the line when the user puts down the handset.

However, if the answering station does not answer the phone, the PIP / PIN signal, which is a Post Message response signal sent by the receiving station, is recognized as normal and the reception is normal. Sounds. At this time, a normal beep sounds a 1 second on / off period, and an error sounds a 0.5 second on / off period.

As described above, in the present invention, when the receiving station sets the receiving result request bit of the receiving station according to the procedure of CCITT T.30 in the facsimile apparatus, the user is notified of the reception result information when the reception is completed. Since it can be confirmed by the external, it is possible to eliminate the hassle of making a call again to check again, there is an advantage that can recognize the status of the transmission result at a distance from the transmitting station.
