Method for board testing in communication system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board diagnostic method of a communication system, and more particularly, to a board diagnostic method of a communication system for outputting a fault state of a board in detail and determining whether a hardware internal function is normally operating.

In general, a communication system performs a state management such as a fault handling and maintenance of a communication system configuration board, collects and analyzes a fault detected during the operation of the communication system, and recovers the identified fault, thereby providing a smooth service for the communication system. To help.

In the conventional communication system, as shown in FIG. 1, when a board diagnosis is requested from a Telephony Common Device Test (TCDT) 1, which is a call path equipment test block 1, to a Device Controller 3 according to an operator's request (S1). The DC (3) receiving the board diagnosis request from the TCDT (1) issues a diagnostic command to the corresponding board (5) (S2), and the corresponding board (5) receiving the diagnostic command from the DC (3) is the DC (3). The predetermined test pattern is transmitted to the time switch 7 under the control of (S3), and the time switch 7 receiving the predetermined test pattern from the board 5 returns the received test pattern to the corresponding board 5 again. Return to) (S4).

As described above, the board 5 which has re-received the test pattern switched by the time switch 7 and returned again compares and analyzes the test pattern transmitted first and the re-received test pattern to determine whether the two signal patterns are the same, so that DC When the test result is reported to (3) (S5), when the two signal patterns are the same as the result of the determination, the test result is reported to the DC (3) that the call path equipment is operating normally, and the two signal patterns are not the same. The test results shall be reported to DC (3) indicating that the line system equipment is not operating normally. As such, the DC (3) reported the test results from the board (5) reports the test results reported from the board (5) to the TCDT (1) (S6), TCDT (1) reports from the DC (3) The test results received are printed to the operator.

On the other hand, when a failure state (Function Fail, Access Fail) occurs on the board, the DC collects the failure state of the board and reports it to the state management block, and the state management block that has reported the failure state from the DC is the reported failure state. The information is reflected in the status table of the library. If there is a status query of the communication system configuration board later, the status information of the communication system configuration board stored in the status management table is output. Here, the status information output according to the status inquiry of the communication system configuration board is comprehensive in content such as a function failure and an access failure.

As described above, in the conventional communication system, the state output as a result of the status management of the communication system configuration board is comprehensive as function failure and access failure, and detailed analysis of the cause of failure of the board is performed. This was impossible. In addition, no diagnostics are provided for the various hardware components constituting the board, such as memory, CPU, digital signal processor (DSP) chips, buses, etc. The analysis was inevitable by (Off-Line).

In addition, in the related art, in order to diagnose a configuration board of a communication system, an operator has to input a diagnosis command through a keyboard, and thus there is a problem that it is not easy to perform a diagnosis unless the operator is skilled in the diagnosis command.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and outputs a fault status register that holds detailed fault conditions of the board, provides a diagnostic function for the components of the board, and provides a graphical user interface (GUI).

And further comprising a processor system board diagnosis process for diagnosing the system board itself.

Hereinafter, a board diagnosis method of a communication system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a road showing the configuration of the board diagnostic apparatus of the communication system in which the board diagnostic method according to the present invention is implemented, the board diagnostic apparatus to which the present invention is applied various communication system devices, for example, subscriber signal, inter-station relay signal, The TCDT 10 performs various tests on the recording guidance device, the conference call device, the time switch, and the like, and is stored in the fault status register of the board 30 from the board 30 to be diagnosed at the request of the TCDT 10.

As such, after a format for outputting different failure state information for each board is configured, when a failure occurs in the board 30 and a board diagnosis request is received from the operator to determine the cause of the failure of the board 30 (S10), The TCDT 10 analyzes the configuration information of the diagnosis target board 30 from the DB (Data Base) (S12), and requests a diagnosis to the DC 20 to perform diagnosis of the corresponding board 30 based on the analyzed information. Transmit the signal (S14).

When the operator performs a board diagnosis request with the TCDT 10 in the above-described process S10, the diagnosis request of the board may request a diagnosis by inputting a previously used command through a keyboard, or by using a GUI. By specifying an icon displayed on the screen in a form or selecting a menu from a list of menu items, diagnosis of the board can be requested.

As such, the DC 20 receiving the diagnostic request signal from the TCDT 10 reads out the fault status information stored in the fault status register of the corresponding board 30 (S16), and shows the fault status of the corresponding board 30. The DC 20 reading the fault state information from the register reports the fault state information read from the fault state register of the corresponding board 30 to the TCDT 10 (S18). When the DC 20 reads the fault state information stored in the fault state register of the board 30 in step S16, data may be read in units of 1 byte.

Accordingly, the TCDT 10 collects the failure state information reported from the DC 20 and outputs the same to the MMC (Man Machine Communication) in accordance with a preset output format for reporting to the operator (S20).

Accordingly, the operator identifies the cause of the failure based on the failure state information output to the MMC, and performs a failure recovery based on the identified cause of the failure.

Figure 4 is a road showing the inspection procedure for each diagnostic item in the board diagnostic method of the communication system according to the present invention, first, to implement the diagnostic process for each item in the board diagnostic method of the communication system according to the present invention comprises a board for each board The diagnosis items for diagnosing the accessory equipment (components), which play an important role in the process, are determined in advance, and the format for determining / outputting the normal operation thereof is first configured. For example, in order to diagnose a VMSC (Voice Message Service Card) for each diagnostic item, the memory, CPU, DSP chip, and bus, which constitute the VMSC, are determined as the diagnostic item.

In this way, after confirming the diagnostic items for each board, if a diagnostic request for each item is received from the operator in order to grasp the state of the components in the board 30 in detail (S30), the TCDT (10) the board 30 In order to check the diagnostic items determined for each board, a signal for requesting a board diagnosis for each item is transmitted to the DC 20 (S32), and a signal for requesting a board diagnosis for each item of the corresponding board 30 from the TCDT 10. Receiving the DC 20 diagnoses the board 30 for each diagnostic item contained in the received signal (S34), and reports the diagnosis result of the board 30 for each diagnostic item to the TCDT (10) (S36). ).

Accordingly, the TCDT 10 outputs the diagnosis result received from the DC 20 to MMC (Man Machine Communication) in accordance with a preset output format in order to report to the operator (S38).

5 is a road showing the automatic diagnostic process of the board diagnostic method of the communication system according to the present invention, when the board 30 is mounted in the communication system (S40), TCDT 10 is a telephone line equipment maintenance processor (Telephony Device From the maintenance handler (TDMH), the configuration information of the board 30 mounted in the communication system is reported in step S40 (S42), and the configuration of the board 30 mounted in the communication system in step S40 described above from TDMH. The TCDT 10 having received the information transmits a diagnostic request signal of the corresponding board 30 to the DC 20 in order to automatically perform the diagnosis of the corresponding board 30 based on the reported configuration information (S44).

As such, the DC 20 receiving the diagnostic request signal from the TCDT 10 reads out the fault state information stored in the fault state register of the board 30 (S46), and shows the fault state of the board 30. The DC 20 reading the fault state information stored in the register reports the fault state information stored in the fault state register of the board 30 to the TCDT 10 (S48). When the DC 20 reads the fault state information stored in the fault state register of the board 30 in step S46, data may be read in units of 1 byte.

Accordingly, the TCDT 10 outputs the failure state information reported from the DC 20 to MMC (Man Machine Communication) in accordance with a preset output format in order to report to the operator (S50).

On the other hand, it is also necessary to determine whether or not the actual function of the board is operating normally, which can be seen through the test to loop back the test pattern in the same way as the conventional description will be omitted.

On the other hand, since the processor-based boards (MIPC, MSIC, DAPC, DC, etc.) that manage the board diagnosis cannot perform their own diagnosis, such processor-based boards are diagnosed with the help of an operating system (OS). As described above, the processor-based boards have only diagnostic items, and the diagnostic items for diagnosing the components of the processor-based boards are determined in advance. For example, to diagnose a main processor IPC card (MIPC) CPU function diagnosis, F / W version check sum diagnosis, memory diagnosis, address bus diagnosis, data bus diagnosis, S-channel diagnosis, D-channel diagnosis, standby memory diagnosis CPU diagnostics, F / W version checksum diagnostics, memory diagnostics, address bus diagnostics, data bus diagnostics, ROM write protection diagnostics, bus error diagnostics, interrupt diagnostics, to diagnose the Main Storage and IO Function Card (MSIC). In order to confirm SCSI bus diagnosis, IO port diagnosis as a diagnostic item, and to diagnose Device Access Processor Card (DAPC), CPU diagnosis, F / W version checksum diagnosis, memory diagnosis, address bus diagnosis, data bus diagnosis, S-channel Diagnosis, TDM loopback test The diagnosis is confirmed as a diagnosis item.

As described above, after the diagnosis items are determined for each processor-based board, the diagnosis is performed with the help of an OS. For example, the main processor, which is one of the processor-based boards, may perform the diagnosis on its own. The direct OS calls an OS primitive for diagnosing the main processor itself, and the OS diagnoses the main processor by sending primitives for diagnosing the main processor to the main processor according to the call of the main processor.

In addition, the diagnosis of the DC 20 is performed by receiving a diagnosis request signal from the TCDT 10. The TCDT 10 transmits a diagnosis request signal to the DC 20 to diagnose the DC 20. The DC 20 receiving the diagnostic request signal from 10) calls an OS primitive for diagnosing the DC 20 itself to the OS, and the OS makes a primitive for diagnosing the DC 20 according to the call of the DC 20. To the DC 20 to diagnose the DC 20, and when all of the diagnosis of the DC 20 itself is complete, the DC 20 transmits the diagnostic result to the TCDT (10). Here, the diagnostic result of the diagnostic item is output as PASS / FAIL / ENV_FAIL, and ENV_FAIL is output when the diagnostic item cannot be performed due to the cause of the corresponding hardware.

The board diagnostic method of the communication system of the present invention is not limited to the above-described embodiments, and may be modified in various ways within the scope of the technical idea of the present invention.

According to the board diagnosis method of the communication system of the present invention as described above, when a board failure occurs, the operator reads the fault status register from the board according to the request of the operator and outputs the fault status register to the operator according to a predetermined format. It is easy to identify the cause of the disorder. In addition, since the diagnosis of each component of the board can be performed for each item, the detailed failure state can be identified. In addition, when the board is mounted in the communication system, the board is automatically diagnosed so that the operator can automatically diagnose the board without inputting a diagnostic command. In addition, by requesting the diagnosis of the corresponding board using the GUI, even an operator who is not skilled in the diagnosis command can easily perform the diagnosis. In addition, the OS primitive may be called to diagnose processor-based boards that manage the board diagnosis.
