When the system is started, a first step (301) of initiating data necessary for testing the general information network subscriber basic access facility, a second step (302) waiting for a test request, a test related data change / view request, Step 3, which creates a process for testing according to the operator's request (303 and 304) when the test request by the operator demand comes, and a process for testing according to the system's own request when the test request due to the system itself demands ( 305 and 306) and the fifth step of generating a process for periodic testing (307 and 308) when the periodic test request comes, and the process of generating a process for this when the request for changing / retrieving data related to the test comes ( 309 and 310) and the seventh step of creating a process (301 and 312) for this, when the test control request comes in, and again after the corresponding work has been processed. A wait is made by the eighth step that returns to the state.

4 is a flowchart showing an embodiment of the third step (303 and 304) operator request test.

The first step (401) for analyzing the command input by the operator in the MMP (2) and delivered to the EC (8) of the OMP (3) to the LTTM (13), and performing the number translation in the LTTM (13) (402) the second step, and the third step of checking the state of the processor and the state of the test equipment (403 and 404), and if the test can be carried out to the DST (14) of the corresponding ASP (4), the DST 14, the fourth step of connecting the test device to the ASMP 6 (405), the fifth step of determining whether the test is possible after the subscriber status check (406), and the subscriber status if the test is possible after performing the fifth step Step 6 (407 to 409) for changing to under test, connecting the digital subscriber test relay to the DSI 20, and transmitting and performing a test execution command to the test device, and receiving the result from the test device, the subscriber state test. The sixth step of changing to the previous state and restoring the test relay (410 to 409), and the test apparatus Upon receiving the result, step 7 of changing to the state before the subscriber state test, recovering the test relay (410 to 412), and transferring the test result to the LTTM 13 after the recovery of the test device is completed, and the test device is not used. The test consists of the eighth step of receiving the test request from the DSI 20, receiving the result, passing the result to the LTTM 13, and delivering the result to the EC 8 for output to the operator (413 and 414).

5 is a flow chart showing a test by the system itself request of the fourth steps 305 and 306 above.

The system self-required test isolates the failure verification test (501) by the request of the FLM 9, the audit test (502) by the request of the PA 19, and the long-term unused subscriber and long-term failure by periodic monitoring. Receives the first step through each of the three types of status check test (506) for the subscriber, the second step (503) for requesting the continuity test to be performed in each path, and the results of the test execution, It checks whether the equipment has failed for basic access of the general information communication network and reports the result in the block that requested the test.After performing the status check test, the test result is reported to the TDMH (10) if there is a state change. Notification (504 and 505) consists of a third step.

6 is a flowchart showing the periodic automatic test of the fifth step (307 and 308).

The periodic automatic test is performed by the DST 14 by itself using a timer, and when a predetermined period is reached, a first step of receiving an automatic test start request (601) and a second step of inquiring test start subscriber information (602) and A third step of selecting a test target subscriber (603), a fourth step of performing a continuity test to receive and analyzing the results (604 to 606), and determining whether there is a failure for basic access to subscribers of the integrated information network; (607) step 5, and reporting to the TDMH 10 to manage the status of the facility for the aggregate information network subscriber basic access and to step 6 such that the tests are repeated until the end of the test (608 and 609). It is composed.

7 is a flowchart for changing and inquiring test-related data after the execution of the sixth steps 309 and 310.

The test-related data change function finds and changes the corresponding data when the operator requests to change the measurement reference value of each measurement yield, the cycle of various automatic tests, and the transmission error threshold value through the input device according to the switching center and the line environment. The first step of re-adjusting the timer accompanied by the change and outputting the result to the operator (701 to 703), and the test management data inquiry function allows the operator to input the measurement reference value of each measurement item through the input device and the cycle of various automatic tests. In response to requesting an inquiry about a threshold value of a transmission error, a second step of retrieving the corresponding data and outputting the data to the operator (704 to 706).

8 is a flowchart of controlling a test after executing the seventh steps 311 and 312.

In test control, the operator allows and prohibits periodic and periodic tests, and the ongoing test is suspended, suspended, or resumed by the operator, and this process is shown in a flow chart.

If the operator requests permission or prohibition of testing and periodic testing by the operator via the input device, the first step of changing and processing the data (801 and 802) for this purpose, and interrupting the ongoing test at the operator's request. A second step of suspending the test (803 and 804) if required; a third step of suspending the test (805 and 806) if the pending test is requested to be suspended by an operator request; When the test is requested to be resumed by the interrupted operator's request, it comprises the fourth step of disrupting the test (807 and 808), and the fifth step of outputting the result to the operator (809).

Therefore, it is possible to perform the various test functions provided by the test apparatus inside the switchboard of the subscriber equipment with the function of the switch itself by incorporating a test device without any additional device, so that the switch may test the basic access facility of the integrated telecommunication network. By configuring the environment so that the failure of the facility for basic information network subscriber basic access can be economically and quickly developed by reducing the cost of additional equipment.
