The present invention relates to a service method of a message handling system (MHS) in a facsimile, and in particular, an interfacing method for receiving voice announcements and pushbutton parameters from a facsimile interface device to a facsimile in order to enable MHS service. It is about.

In general, it is known that the facsimile needs to prepare a protocol of P5, a communication protocol of MHS, in order to be serviced by a message processing system (hereinafter referred to as "MHS"). Because the facsimile can't transmit arbitrary data using the keyboard, unlike a personal computer or a texttext, it must be able to transmit the parameters required for the P5 protocol for MHS service. For this purpose, the image scanner can be used to digitize the data from the facsimile, but this has been ineffective hardware or software.

Accordingly, an object of the present invention is to provide a method for receiving a telephone connected to a facsimile via a push button, through voice guidance, parameters of a P5 protocol, a communication protocol of MHS, to provide MHS service to facsimile users. have.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a system block diagram for carrying out the present invention, and FIG. 1 is a known configuration system of a plurality of facsimile 101 and telephones 102, an exchanger 103, and a main control processor for controlling the entire system. (MCP) 8 and the facsimile 101 connected to the exchange 103 via the telephone 102 to receive a block-by-block service request from the facsimile 101 or to transmit the service contents to the facsimile 105. Facsimile interface unit (FIU) 11 for processing a function to make a function, and various status signals generated from the inside and various signals notified from the outside to detect the smooth data transmission and reception between the MCP (8) and the FIU (11) The main control unit (FCP) (10) and the image data transmitted and received through the FIU (11) to enlarge / reduce or encode / decode, or at the same time to output the code to the FAX terminal as an image An image control processor (ICP) 12 performing a function of converting, a hard disk 104 for storing a mailbox, and a propi disk 105 for a hard disk backup are provided to store and transmit data of the facsimile 101 upon reception. And a Peripheral Control Processor (PCP) 105 which outputs the data stored at the time.

2 is a detailed block diagram of the FIU 11 in FIG.

First, the FIU 11 and the FCP 10 will be described before the overall system description.

As shown in FIG. 2, the network control unit (NCU) 23 is a device that is directly connected to the private exchange (PABX) 103 to control the connection to various devices in the FIU 11.

When a ring comes in from the phone 102, a ring detector in the NCU 23 detects the ring and informs the CPU 14 directly, and the CPU 14 tells the MCP 8 the ring. It sends an error notification that the ring is coming and then instructs the NCU 23 to connect the data bus. At this time, when a command to output voice from the MCP 8 to receive push button data is received, the CPU 14 receives the voice data of the EPROM 18 through the codec 21. Print to the user. When a user hears a voice signal and transmits PB data (combination of 0-9, ＃, *) to the DTMF receiver (DTMF-R) 20 by using a push button (PB) of the telephone 102, The DTMF-R 20 converts the analog data into digital, filters the interrupts with the interrupt controller (INTC) 16, writes the PB data to the designated buffer in the RAM 19, and directs it to the direct memory access controller (DMAC) ( 15) to the FIFO (17) and to the MCP (8). When the voice output and PB data reception is repeated such that all PB data reception is completed, the phone is finally hooked on and the voice output is requested to press the communication button of the facsimile 101.

Thereafter, T. 30 protocol communication is performed between the facsimile modem and the modem 22 in the FIU 11. At this time, the protocol information is sent and received, such as the type of the facsimile, the line speed, the font mode, etc. If this rule is established, the actual FAC image data is transmitted to the FCP 10 by using the MODEM (22) and DMAC (15). Receiving the message information of the MCP (8) is transmitted to the PCP 13 in block units. When the transmission is completed, the line is disconnected to send the other facsimile. To find and connect a new free line, the data is transmitted by the other facsimile in block units. When the transmission is completed, the line is disconnected and the transmission is completed. .

First, upon reception, image data is received from the FIU 11 and written to the hard disk 104 or floppy disk 105 of the PCP 13 according to the MCP 8 instructions, and the message information of the MCP 8 is transmitted at the time of transmission. In this manner, the PCP 13 transmits information in units of blocks from the PCP 13 to the FIU 11. In addition, in consideration of scalability, it is possible to connect several FIUs 11 to one FCP 10. The FCP 10 performs an interface function with the PCP 13 during transmission and reception, and the expansion of the FIU 11 is easy.

The operation of the present invention will be described with reference to FIG.

When the user hooks off the handset of the telephone 102 to transmit the facsimile data, the PABX 103 sends a ring tone to the CPU 14 and outputs a ring back tone to the user. do.

The CPU 14 detects an on-line physical line and sends a communication message to the FCP 10 through the FIFO 17. The FCP 10 sends the MPC 26 to the MCP 8; Send a communication message through. At this time, the MCP 8 analyzes the communication message, detects the call notification that the ring is coming, and transmits the communication message via the FCP 10 to the FIU 11 to receive control data. The FIU 11 connects the data bus when the NCU 23 detects the ring tone, and the CPU 14 analyzes the communication message.

Since the message has a command to output a voice for receiving control data, the voice data of the EPROM 18 is sent out to the user's telephone 102 through the CODEC 21. A character string that is a combination of (0-9, *, ＃) is input through the push button PB of 102. The DTMF-R 20 which receives the PB data converts the input analog signal into a digital signal, stores it in the RAM 19, transfers it to the MCP 8 through the FIFO 17 by the DMAC 15, and transmits the MCP ( 8) dictates voice output until all PB data is received and performs the repeated task of receiving PB data. When the MCP 8 receives all of the PB data by the above operation, the FIU 11 sends the MCP 8 a notification of completion of voice output and reception of the PB data. At this time, when the user puts the telephone according to the last voice output and presses the communication button of FAX, the telephone line is disconnected from this time, and the facsimile line is connected, and communication between the facsimile 101 and the FIU 11 is performed. The T.30 protocol is performed with the MODEM 22 in the FIU 11 to determine the type of the facsimile, the line speed, and the setting of the normal fine mode.

After the progression, the MCP 8 receives the data of the block (8K) unit from the FIU 8 and indicates that the image data of the facsimile may be sent to the FIU 8. By using the function, the reception of the image data is completed and the service of the application S / W 7 in the MCP 8 is received.

At this time, the work done by the application S / W 7 is related to the Message Handling System (MHS) recommended by the CCITT and is provided with services such as mailbox management and other broadcasting and time designation. While the service line of the application S / W (7) is being serviced, the connection line used for reception was rested so that the connection line was cut off and this line could be used by other users. to be. There are logical lines and physical lines.

Logical lines correspond to 1: 1 with physical lines and are the same concept as IDs of physical lines used to check whether a physical line is in use. In order to manage the logic line, a management table is placed in the FSRP 3 to manage the state of the physical line used for FAX transmission and reception.

When all lines are in use, wait for retry. The physical line refers to four lines that are actually connected to the FIU 11 which is H / W, and manages these lines in the FIU 11.

The reason for managing along the logical line and physical line is to receive and receive the service of the application S / W, and to transmit and receive only when receiving the correspondent fax. While receiving the service of the application S / W after receiving the line that is currently connected After the service is freed, the service manager checks whether there is a free line again in the line management table and connects a line that is not in use to transmit. That is, it is a technique to save the unused time of the physical line between transmission and reception.

When the service of the application S / W 7 is finished, a job for transmitting the received image data to the other party's facsimile is developed. First, since the line was disconnected when reception was completed, a new line must be connected. To do this, the MCP (8) manages the logical line and checks whether it is in use by the logical line management table. If there is an unused line, it grabs the line and informs the FIU (11) of the fact. The actual line is connected and the MCP 8 is notified of the connection result.

Then, the MCP 8 sends the block data of the facsimile data to the FCP 10 and the block data is transmitted between the FCP 10 and the PCP 13.

3 is a flowchart according to the present invention, which detects a ring signal and notifies the facsimile service center as a voice message and checks an overload state of the reception control buffer, and congestion when the reception control buffer is overloaded in the first process. The second step of requesting the registration number when the service information is not overloaded by a voice message, and a registration number is input in accordance with the registration number input request of the second step, checking whether there is a registration number error. If there is a registration error is not registered, the third step of re-entering or sending the registration number as a voice message, and when there is no registration error in the third step, and outputs a voice message requesting the input of the corresponding service code By inputting the service code into the professional transmission service, check the status in the actual mailbox, professional output, professional transmission parameters A fourth step of checking reception-specific information, and outputting a voice message requesting a corresponding transmission code input when receiving the parameter of the specialized transmission service in the fourth step, and whether there is an error of the transmission code input from the request for inputting the transmission code. A fifth step of outputting a message to re-enter the number entered when there is an error by checking a; and outputting a request message to input a corresponding detailed code when there is no error in the transmission code in the fifth step, and outputting the corresponding detailed code Step 6 to check whether there is an error in the detailed code entered according to the input request, to output a message to re-enter the number input when there is an error, and to output a request message to input the telephone number of the destination where there is no error. And the presence or absence of an input line telephone number error according to the telephone number input request message of the output destination of the sixth process. The seventh step of entering a hook-on state to output a message for inputting the input number again when there is an error and to send a message to press the facsimile communication button if there is no error; and the state of the actual mailbox in the fourth step. When the check parameter is received, a message for inputting a telephone number is sent, and if there is an error, a message for inputting a current telephone number is checked. When the application was received, the application was sent to send the message to hang up the handset and enters the hook-on state. If there is an error, check whether there is an error of the entered code according to the search identification code input. Sending a message to re-enter the number that has been entered, and if there is no error, the ninth step of sending a message to input the corresponding detail coat, and in the ninth step checks whether there is an error of the input code according to the corresponding detail code input If there is an error, send a message to re-enter the currently entered number, and if there is no error, send a message to input the phone number of the output. Check the presence or absence of the input line number error according to the phone number input. If there is an error, send the message to input the current number again, and if there is no error, the application is received. When the parameter required for transmission is received, a message for inputting the corresponding transmission code is sent. Checking the presence or absence of an error in the input code according to the code input and sending a message to input the current number again when there is an error, thereby checking the presence or absence of the error in the detailed code input according to the corresponding detailed code input And a message to re-enter the currently entered number when there is an error in step 11 and a message to input a phone number of a place to be output when there is no error, thereby inputting a phone number of the received place. Checking the error of the output line telephone number, and sending a message to re-enter the current number when there is an error, and receiving the application when there is no error, sending a message to hang up the handset and entering the hook-on state. It consists of 12 steps.

4 is a detailed flowchart of (3b) according to the present invention, FIG. 5 is a voice output table according to the present invention, and FIG. 6 is a pushbutton parameter table according to the present invention.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1-6. In step (3a), the ring bit setting unit of the NCU 23 is checked by polling in the central processing unit 14 of FIG. At this time, if the PABX 103 sets the ring bit setting portion of the NCU 23 as the flag for the ring according to the subscriber's ring, the PABX 103 performs the ring check by processing as an interrupt. The CPU 14, which has confirmed the ring test, notifies the first degree MCP 8 of the signal that there is a ring, accesses the EPROM 18 under the control of the MCP 8, and accesses the predetermined address 01 of the RAM 19. This is the facsimile service center that you specify. The facsimile subscriber phone 102 that reads Vø1 data, passes through the shifter 21, converts it into an analog signal at the codec 21, and is connected by the PABX 103 through the NCU 23. Send through). Next, in step 3c, the CPU 14 checks whether the reception control (RCB) buffer of the RAM 19 is overloaded.

When the reception control buffer (RCB) is overloaded in step (3c), it informs the MCP (8) that the CPU 14 is overloaded in step (3d) and designates the address of the RAM 19 as shown in FIG. “The service was not received because it is crowded right now,” leads the data (SB). The read data SB is converted into an analog signal in the CODEC 21 through the shifter 21 and sent out through the NCU 23 to the facsimile telephone 102 connected to the PABX 103, and the line is disconnected.

When it is not overloaded in step (3c), the CPU 14 informs the MCP (8) that it is not overloaded in step (3f), and designates the address of the RAM 19 as shown in FIG. Read the data Vø2. The read data V ø2 is sent out to the facsimile phone 102 in the same manner as the above method, and in step 4f, the facsimile number of the user-specific user-specific password is transmitted from the facsimile phone 102 to the phone 102 keyboard as shown in the table of FIG. Enter a 4-digit digit via.

When the input 4-digit digit is received by the DTMF-R 20 through the PABX 103 and the NCU 23, it is digitized and stored in the RAM 19 under the control of the CPU 14. When there is an error in step (3g), in step 3i, the CPU 14 notifies the MCP 8 and assigns the address 10, 11 to the RAM 19 as shown in FIG. Then, please try again. Or, enter the current number once again. Read the data (S14, S15) corresponding to this and send it to the facsimile side phone 102 as described above.

However, when there is no error of registration number in step (3h), in step (3j), the CPU 14 assigns the address of RAM 19 as V04 in Fig. 5, and inputs the corresponding service code. When (Vø3) is sent to the telephone 102, the subscriber receives the service code of the two digits as shown in the table of FIG. 6 through the keyboard of the telephone 102 in the process (3k). Check in the process. You can check the service function about 4 digits here. If you list them as follows:

The ability to receive the parameters required to perform the first transmit / receive service, the ability to receive the parameters required to determine the status of the second actual mail box, the ability to receive the parameters required for the third professional output, Check the function to receive the parameters required for the fourth professional transmission.

In the process of receiving the professional transmission parameter in the process (3l), the CPU 14 informs the MCP (8) that the transmission of the professional transmission parameter is received as shown in FIG. 5 in the process of (3m), and designates the address of the RAM 19 to determine the corresponding transmission code. Enter the data ＂4 and send it to the facsimile-side telephone 102 in the same manner as described above. At this time, if the user inputs a predetermined digit through the keyboard of the phone 102 as shown in the table of FIG. 6 in the process (3n), the transmission code inputted by the CPU 14 and left in the RAM 19 as described above is an error. If there is an error in the process (3o), in step 3p, in the process (3p), designate the number 11 of the RAM 19 as shown in the table of Fig. 5, and enter the current number again. S15 is sent to the facsimile telephone 102.

When there is no error in step (3o), the CPU 14 notifies the MCP 8 that there is no error, and in step 3q, a predetermined address of the RAM 19 is designated as shown in the table of FIG. Enter the detailed code ＂and send the data Vø6 to the phone 102.

When the detailed code is input as shown in FIG. 6 in the process of subscriber 3r of the telephone 102 which has received the data V6, it is input according to the limit of the table of FIG. 6 in the process of 3S. Check the detail code for errors. In step (3s), if there is an error in step (3s), the same process as in step (3p) is performed and when there is no detailed code error, the CPU 14 sets the predetermined address of the RAM 19 in step (3u). Specify as shown in Fig. 12 and read the data (V11), "Please enter the phone number of the destination of the output" and transmit it to the telephone 102 side. When the subscriber who has heard the transmission signal inputs the output line telephone number in step 3v through the keyboard of the telephone 102, the CPU 14 checks whether there is an error in the input line number in step 3w. do. When there is an error in step (3w), the same operation as in (3p) is performed in step (3x), and when there is no error, the CPU 14 moves to a predetermined address in the RAM 19 as shown in FIG. Is designated as 01, and the data V ø8 is sent to the telephone 102 and hooked on.

When receiving the parameter to check the actual mailbox status in step (3l), the CPU 14 designates the predetermined address of the RAM 19 as shown in FIG. Enter the number ＂to send the data V11 to the phone 102. Accordingly, if the subscriber inputs the output line telephone number from the 4b through the keyboard of the telephone 102 to the digit within 22 digits as shown in the table of FIG. 6, the process (4c) is performed by the output line telephone inputted in the process (4b). Check if there is an error in the number. When there is an error in (4c), the process is executed as in (3p) in (4d) and when there is no error, the CPU 14 causes the predetermined address of the RAM 19 to be reset as shown in FIG. If you send the data (V12) to the phone 102, "You have received the application because you have received the application." (4f), it enters the hook-on state.

In the case of the parameter reception required for the full text output in step (3l), the CPU 14 designates a predetermined address of the RAM 19 in step (4g) and designates address 08 as shown in the table of FIG. At this time, read the data “Vø9” in RAM 19 and send it to the telephone 102. Then, in step 4h, the subscriber sends the search identifier digit of the phone 102 in step 4h. Enter as shown in Figure 6 through the keyboard. Check whether the search identification and the dodge inputted in the above (4h) are error by 4 alphanumeric characters. If there is an error in step (4i), proceed to step (3p) in step (4j), and if there is no error, in step (4k), enter the detailed code (Vø6). When the subscriber transmits to 102, the subscriber inputs the detailed code in step 4l through the keyboard of the telephone 102 and checks whether the detailed code input in step 4m is error free. If there is an error in step (4m), execute as in step (3p), and if there is no error, in step (4p), enter the phone number where the CPU 14 receives the output from the RAM (19). The telephone 102 transmits the data V11.

When the output line telephone number is input through the keyboard of the telephone 102 in step 4g by the transmission message of step 4p, it is checked whether there is an error in the telephone number in step 4r. If there is an error in step (4r), execute step (4s) as in step (3p), and when there is no error, in step (4t), in the RAM (19), the application was received. Send V12 to enter the hook-on state.

In step (3e), when receiving the parameters necessary for the professional transmission, in step (4u), the CPU 14 designates a predetermined address of the RAM 19 as shown in No.05 of the table of FIG. 5 and inputs the corresponding transmission code. If the data V ø4 is sent to the telephone 102, the corresponding transmission code is input through the keyboard of the telephone 102 in step (4v).

The CPU 14 checks if there is an error in the transmission code input in step (4v) and executes step (4x) as shown in step (3p) when there is an error. 19), enter the corresponding detail code. Read the data (Vø6), analogize it, and send it to the telephone 102 side.

When the detailed code is input in step 4z according to the transmission message of (4y), the CPU 14 checks whether there is an error in the detailed code input in step (5a). If there is an error in step (5a), execute step (5h) as in step (3p), and if there is no error, specify a predetermined address of RAM 19 as shown in FIG. 5 table in step (5c). Read the data (V11) and send it to the telephone (102). According to the message sent out, if the subscriber inputs the output line telephone number through the keyboard of the telephone 102 in step 5d, it checks whether there is an error in the telephone number input in step 5e.

When there is an error in step (5e), step (5f) is executed as in (3p) above, and when there is no error, in step (5g), the predetermined address of RAM 19 is designated as No. 09 to accept the application. Please take down the handset. ＂Read the data V12, analogize it in the CODEC 21, and send it out to the telephone 102 side.
