The conventional G3 protocol measuring apparatus has a monitor function capable of measuring the communication protocol of the facsimile apparatus, detects the communication protocol during transmission and reception by the facsimile apparatus, and displays the result on a screen or a recording sheet. The analyzed result is analyzed by an analyst to determine the suitability of the communication protocol. [0003] However, the monitored communication protocol data is determined by a standard value defined in FTZ18TR53 or by a manufacturer of each facsimile apparatus based on FTZ18TR53. It is not easy to analyze whether or not the
It required specialized knowledge and quite a long time for analysis. Further, since the analysis of the communication protocol is not easy, the analysis result may vary from analyst to analyst or omit the analysis, which may be one of the causes of communication failure. In addition, since it is not easy to reconfirm the analysis result and to reproduce the result of monitoring to take measures against the cause of the communication failure, it is necessary to investigate the cause of the communication failure when it occurs. It was difficult to take quick measures.

The extracted non-standard procedure communication protocol sequence is sequentially compared with the measurement data of the communication protocol for each item (step S32). As a result of the comparison, if the measurement data of the communication protocol is different from the non-standard procedure communication protocol sequence specified by the manufacturer, an error message is generated and displayed in a different portion. It is displayed on the unit 3 (steps S33, S34). As a result of comparison, if 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 unit 3.

Next, the digital handshaking command in the measurement data of the communication protocol is sequentially transmitted and received with the transmission side command based on the nonstandard procedure communication protocol sequence defined by the extracted manufacturer. It is separated into side commands (step S52). Then, the function information of the digital handshaking command on the transmitting side (transmitting side or receiving side) for executing the simulation is extracted, and the modem 52 of the communication control unit 5 for the simulator is controlled from this function information. Then, modem control information for transmitting or receiving high-speed data is extracted and set as simulation data in the modem control table storage unit 18 (step S53).

The protocol sequence defined by R53 is extracted from the protocol sequence table storage unit 17 (steps S49 and S50). Next, the digital handshaking command of the measurement data of the communication protocol is sequentially separated into the transmission side command and the reception side command based on the protocol sequence defined by the FTZ18TR53 (step S52). .

To S57). Since the communication protocol equivalent to that of each facsimile machine is executed by using the communication program data measured in this way, the situation of the communication failure can be reproduced and confirmed. Measures can be taken reliably. In the above-described simulation processing, a case has been described in which, as a result of judging the suitability of the measured communication protocol data, the judgment result is immediately reproduced and confirmed. However, the communication protocol of a plurality of facsimile apparatuses is measured. After judging the suitability, the simulation data subjected to the simulation processing is stored in a data storage memory 2 such as a floppy disk, and a plurality of communication protocol data are collectively and continuously reproduced. Then, it is also possible to execute communication program data equivalent to each facsimile machine, confirm the reason of the communication failure, and take measures against it. The operation in this case will be described with reference to the flowchart of FIG.

When the simulation data for one communication is stored in the RAM 13, the CPU 11 transfers the simulation data to the communication controller 5 for the simulator. When the communication simulation control unit 5 is instructed to perform the continuous execution of the simulation and the communication simulation data is sent, the communication control unit 5 establishes a line based on the received simulation data and executes the simulation.
(Steps S63, S6)
4). For the continuous execution of this simulation, for example, when the line is connected to the facsimile machine 6, when the facsimile machine 6 prints out the communication management report and is not ready for reception, If the line is not established (step S64), the communication control unit 5 for the simulator repeats the calling operation at regular time intervals (step S65). If the line is not established even after repeating this call a predetermined number of times (step S66,
S67), the simulation continuous execution process is temporarily terminated. When the line is established, the communication control unit 5 for the simulator
Sends out the simulation data to the line based on the contents of the sent simulation data and executes the simulation (steps S68 and S69). The result of the executed simulation is measured by the monitor communication control section 4, and the monitor arithmetic processing section 14 determines whether the communication protocol is appropriate. This measurement result is given the same name as the data name of the executed communication simulation data, and together with the judgment result of the communication protocol, the data storage memory 2.

Numeral 11 denotes simulation data for the next communication from the data storage memory 2 in which simulation data is recorded.
Data is extracted and stored in the RAM 13 (step S72), and a simulation is executed in the same manner as described above based on the extracted communication simulation data (steps S73 and S73).
68-S71). This process is automatically repeated for all the communication simulation data recorded in the data storage memory 2, and the results of the simulation by all the communication simulation data are stored in the data storage memory. After recording in No. 2, the process ends (step S73). As described above, the simulation is automatically executed for all the communication simulation data recorded in the data storage memory 2, and the result is recorded in the data storage memory 2. A communication test can be performed without the need for a communication test, and a communication test can be performed at midnight or the like when normal communication is not hindered. In addition, since the communication simulation data recorded in the data storage memory 2 and the simulation execution result can be quickly checked, the time required for the analysis work can be significantly reduced and the communication failure can be reduced. The cause can be accurately confirmed, and the countermeasure can be taken promptly. According to the present invention, as described above, FTZ

Even people who do not have specialized knowledge can carry out the work accurately in a short time. Therefore, it is possible to prevent a variation in analysis accuracy for each analyst and to prevent an analysis leakage, and to perform a stable analysis. Further, by converting the measured communication protocol data into communication simulation data and executing the measured communication protocol, the cause of the communication failure can be accurately reproduced, and the communication failure can be reduced.
