When the monitor communication control unit 4 receives the communication protocol data including the image information data, the CPU 11 of the control unit 1 sends the digital handshaking command NSF by the low speed modem (300 bps) of the modem 3. It is confirmed whether or not the data has been received (step S1). When the NSF is detected, the maker code is detected by the 17th to 28th bits of the facsimile information field (FIF) of the NSF and the RAM is detected.

If there is DCS next to NSS in the communication protocol data being measured (step S10), if there is data set in RAM 13, the set data is reset. (Steps S11 and S12), ITU Recommendation T. The function information table defined in 30 is extracted from the function information table storage unit 14 (step S13).
Based on the extracted function information table, the modem mode of the modem 42 of the monitor communication control unit 4 is switched, the communication protocol data is measured and stored in the RAM 13 (step S14). If DIS is detected from the received communication protocol data without detecting NSF (step S9) and subsequently DCS is detected (step S10), IT
U. Recommendation T. The function information table defined by 30 is extracted, and the communication protocol data is measured in the same manner as above (steps S11 to S14). The CPU 11 repeats the above processing, and when the measurement of the communication protocol data is completed (step S15), the measurement data stored in the RAM 13 is stored in the data storage memory 2 such as a floppy disk (step S16).

Next, the processing for detecting the document size of the image information data of the communication protocol data measured as described above will be described with reference to the flowchart of FIG.

When the operation for calculating the document size of the image information data of the communication protocol data is started (step S21), the CPU 11 of the control unit 1 specifies the specified communication protocol stored in the data storage memory 2. RAM for extracting measurement data

The manuscript size calculation processing section 19 extracts the line end signal EOL from the image information data detected by the high speed modem of the communication protocol measurement data stored in the RAM 13, and calculates the number of the extracted line end signal EOL. Counting is performed until the control return code RTC appears (steps S23 and S24). Next, during the measurement data of the communication protocol, the digital handshaking command NS detected by the low speed modem of the monitor CCU 4 is detected.
If S is present (step S25), the maker code is detected by the 17th to 28th bits of the NSS facsimile information field (FIF) (step S26).

If there is no digital handshaking command NSS in the communication protocol measurement data but there is a digital handshaking command DCS (steps S25, S28), the data set in the RAM 13 is set. If there is data such as a card code, the set data is reset (steps S29, S).
30), ITU Recommendation T.

When this message processing is repeated and the message end signal EOM is detected, the calculated document size is displayed on the display unit 3 and the document size calculation process ends (step S35).

By calculating the document size (length) of the image information of the communication protocol data monitored in this way, the reading error of the scanner of the facsimile apparatus 6 on the transmission side can be detected, It is possible to determine whether or not there is an abnormality in the scanner of the facsimile device 6 on the side.

Next, the processing for determining the suitability of the communication protocol data measured as described above will be described with reference to the flowchart of FIG.

When the operation for judging the suitability of the communication protocol data is started (step S41), the CPU 11 of the control unit 1 extracts the measured data of the specified communication protocol stored in the data storage memory 2. Then, the data is stored in the RAM 13 (step S42). When the monitor arithmetic processing unit 14 confirms the NSF from the measurement data of the communication protocol stored in the RAM 13 (step S43), the maker code is read by bits 17 to 28 of the facsimile information field (FIF) of the NSF. Mode is detected and set (step S44). Then, when the NSS which is the response signal to the NSF is detected (step S45), based on the detected maker code,
A non-standard procedure communication (unique communication) protocol sequence defined by the manufacturer is extracted from the protocol sequence table storage unit 17 (step S46).
The extracted non-standard procedure communication protocol sequence and the communication protocol measurement data are sequentially compared for each item (step S52). As a result of this comparison, if the measurement data of the communication protocol differs from the non-standard procedure communication protocol sequence defined by the manufacturer, an error message is generated and displayed in a different part. It is displayed on the section 3 (steps S53 and S54). As a result of comparison again,
When the measurement data of the communication protocol is the same as the non-standard procedure communication protocol sequence defined by the manufacturer, a normal message is generated and displayed on the display section 3 (step S53, S55).

Further, the monitor arithmetic processing unit 14 is the RAM 1
When DCS is detected next to NSS from the measurement data of the communication protocol stored in step 3 (step S48), the set maker code is reset and ITU Recommendation T.38. Thirty

This extracted ITU recommendation T.264. 30 is sequentially compared with the measurement data of the communication protocol for each item, and the measurement data of the communication protocol is determined by ITU Recommendation T.30. If it is different from the protocol sequence defined by 30, an error message is generated and displayed on the display unit 3 (steps S52, S53, S54). Also,
As a result of the comparison, the measurement data of the communication protocol is T. If it is the same as the protocol sequence defined by 30, a normal message is generated and displayed on the display unit 3 (steps S52, S53, S55).

If DIS is detected without detecting NSF from the measurement data of the communication protocol (step S47) and DCS is subsequently detected (step S48), the measurement data of the communication protocol and the ITU recommendation are obtained as described above. T. The protocol sequences defined by 30 are compared to determine the suitability of the measured communication protocol data (steps S49 to S55).

Since the propriety of the communication protocol data thus measured is automatically judged and the presence or absence of an abnormality is displayed according to the protocol sequence, the propriety of the communication protocol can be confirmed easily and accurately. be able to.

The maker code is detected by bits 17 to 28 of (IF) and set in the RAM 13 (step S64). When the NSS which is the response signal to the NSF is detected (step S65), the non-standard procedure communication (unique communication) protocol sequence defined by the manufacturer is determined based on the detected manufacturer code. Protocol sequence
It is extracted from the bull storage unit 17 (step S66). Next, based on the non-standard procedure communication protocol sequence defined by the manufacturer that extracted the digital handshaking command in the measurement data of the communication protocol, the command and the receiver of the sender are sequentially received. The command is separated (step S72). Then, the function information of the digital handshaking command of the sending side (sending side or receiving side) that executes the simulation is extracted, and the modem 52 of the communication control section 5 for the simulator is controlled from this function information. The modem control information for transmitting or receiving the high speed data is extracted and set in the modem control table storage unit 16 as simulation data (step S73). After separation of all digital handshaking commands of the measurement data of the communication protocol and extraction of the modem control information, the simulation is completed.
When the simulation data save is designated, the data communication control unit 5 stores the simulation data set in the modem control table storage unit 16.
The data is recorded in the data storage memory 2, and the data is transferred to the simulator communication control unit 5 (step S74,
S75). The communication control section 5 for the simulator executes the simulation by connecting the lines based on the sequence of the sending side (transmitting side or receiving side) which executes the sent simulation (steps S76, S77). . Then, the result of the executed simulation is measured by the monitor communication control unit 4, the monitor arithmetic processing unit 14 determines whether the communication protocol is appropriate, and the result is displayed on the display unit 3 according to the sequence.

Also, the arithmetic processing unit 15 for simulation.

8), the setup data is reset and ITU Recommendation T. The protocol sequence defined by 30 is extracted from the protocol sequence table storage unit 17 (steps S69, S70, S71). Next, the ITU Recommendation T.3 which extracts the digital handshaking command of the measurement data of the communication protocol. Based on the protocol sequence defined by 30, the transmission side command and the reception side command are separated sequentially (step S).
72). Then, the function information of the digital handshaking command of the sending side (sending side or receiving side) that executes the simulation is extracted, and the modem 52 of the communication control section 5 for the simulator is controlled from this function information. Modem control information for transmitting or receiving high speed data is extracted and set in the modem control table storage section 18 as simulation data (step S7).
3). After the separation of all digital handshaking commands of the communication protocol measurement data and the extraction of the modem control information are completed, the simulation arithmetic processing unit 15 operates in the same manner as described above. The simulation data set in the storage section 18 is recorded in the data storage memory 2 and transferred to the simulator communication control section 5 to execute the simulation (steps S74 to S77). In addition, the communication protocol measurement data

8), ITU Recommendation T. The simulation data is extracted based on the protocol sequence defined by 30 and the simulation is executed (steps S69 to S77).

Since the communication program data measured in this way executes the communication protocol equivalent to that of each facsimile apparatus, the situation of the communication failure can be reproduced and confirmed, and the reason for the communication failure can be clarified. Measures can be taken reliably.

When determining the suitability of the communication protocol data as described above, the setting data of the line deterioration factor data such as the link characteristic of the exchange system, the line length and the line capacity is connected to the measurement environment. By setting it in the exchange 7, the simulation processing including the influence of the line deterioration factor can be performed. The operation in this case will be described with reference to the flowchart of FIG.

A switch data setting process is selected by an operation unit (not shown) (step S81), and the switch system includes link deterioration factors data such as link characteristics, line length, line capacity, and the like. When the data is set, C of the control unit 1
The PU 11 sequentially stores the set exchange data in the exchange data storage unit 21 (steps S82 and S83). When the save of the exchange data stored in the exchange data storage unit 21 is selected, the CPU 11 stores the exchange data stored in the exchange data storage unit 21 in the data storage memory 2 as well. It is recorded (steps S84, S85). When the simulation process is started in this state, the simulation arithmetic processing unit 15 reads the exchange data stored in the exchange data storage unit 21 and sets the exchange of the simulator communication control unit 5. Transfer to section 56. The exchange setting unit 56 of the simulator communication control unit 5 transfers the exchange data including the link characteristic, line length, line capacity and other line deterioration factor data to the exchange 7, The line deterioration factor data and the like are set in the exchange 7 (step S86). After that, the simulation arithmetic processing unit 15 determines the simulation data.
The simulator is transferred to the simulator communication control unit 5 and simulated.
Solution processing is executed (steps S87, S88).

In this way, the environment condition in which the facsimile apparatus is actually used in the market is reproduced to simulate the environment.
Application processing can be executed.

In addition, the exchange connected to the measurement environment
As for the exchange data including the line deterioration factor data to be set, it is possible to set different exchange setting data to each simulation data, and to set different communication failure environments. It can also be executed for each simulation data. In addition, it is possible to set the status of exchanges in countries other than Japan to the exchange data including line deterioration factor data, etc., and the facsimile machine is actually used even for communication failures occurring in countries other than Japan. It is possible to reproduce and simulate in the existing environment.

In the above-mentioned simulation processing, a case has been described in which the propriety of the measured communication protocol data is judged, and the judgment result is immediately reproduced and confirmed. However, the communication protocol of a plurality of facsimile machines is measured. After determining its suitability, the simulation data that has been subjected to the simulation processing is stored in the data storage memory 2 such as a floppy disk, and a plurality of communication protocol data are collectively and continuously reproduced. However, it is also possible to execute the communication program data equivalent to that of each facsimile apparatus, confirm the reason for the communication failure, and take the countermeasure. The operation in this case will be described with reference to the flowchart of FIG.

When the continuous execution process of the simulation is instructed (step S91), the CPU 11 of the control unit 1 causes the simulation data for one communication from the data storage memory 2 in which the simulation data is recorded. -Extract data and R
It is stored in the AM 13 (step S92). When the simulation data for one communication is stored in the RAM 13, the CPU 11 transfers the simulation data to the communication control unit 5 for the simulator. The communication control unit 5 for simulator executes a simulation by concluding a line based on the transmitted communication simulation data (step S).
93, S94). The result of the executed simulation is measured by the monitor communication control unit 4, and the monitor arithmetic processing unit 14 determines the suitability of the communication protocol. The measurement result is recorded in the data storage memory 2 with the same name as the data name of the executed communication simulation data and the judgment result of the communication protocol (step S).
95). When the simulation for one communication is executed and the measurement result is recorded in the data storage memory 2 (step S96), the CPU 11 reads from the data storage memory 2 in which the simulation data is recorded. The simulation data for the next communication is extracted and stored in the RAM 13 (step S97), and the extracted communication simulation data is extracted.
Based on the data, simulation is executed in the same manner as above (steps S98, S93 to S96). This process is
All the communication simulation data recorded in the data storage memory 2 are automatically repeated, and the simulation results by all the communication simulation data are recorded.
When the data is recorded in the data storage memory 2, the process is terminated (steps S97, S98).

In this way, the simulation of all the communication simulation data recorded in the data storage memory 2 is automatically executed and the result is recorded in the data storage memory 2. The communication test can be carried out without requiring the communication, and the communication test can be carried out at midnight when there is no problem in normal communication. Further, since the communication simulation data recorded in the data storage memory 2 and the execution result of the simulation can be quickly confirmed, the time required for the analysis work can be greatly shortened and the communication failure can be prevented.
