Inspection execution means for executing a state inspection of the communication system when the time and date of measurement coincides with the communication system state inspection date and time of the date and time storage means, and an inspection result storage means for storing inspection results by the inspection execution means,
The test result output means outputs the test result stored in the test result storage means when the time and date measured by the time measuring means matches the test result output time and date in the date and time storage means.

According to the present invention, an inspection execution means for executing an inspection of the state of the communication system by an instruction from an external computer connected via a modem from a main unit in the communication system, and an inspection result by the inspection execution means are stored. And an inspection result output unit that outputs the inspection result stored in the inspection result storage unit according to an instruction from the external computer.

[0010]

As a result, according to the present invention, the state inspection date and time and the inspection result output date and time of the communication system, which are set in advance, are stored respectively, and the date and time are clocked, and the measured date and time coincides with the communication system state inspection date and time. Perform a state check,
Since the inspection result is stored and the inspection result is output when the time and date and time coincide with the inspection result output date and time, the failure inspection is automatically performed at a desired date and time without stopping the operation of the communication system. The inspection result can be obtained at a desired date and time.

In step 408, the failure state determination section 214 determines that there is a failure, and the information of the station line interface units 41 to 4n corresponding to the failure data area in the data storage section 213 is stored (step 409).

When it is detected that the fault inspection of all the station line interface units 41 to 4n is completed (step 410), the check flag is turned off and the process is completed (step 411).

Each station line interface unit 41
If the station lines 51 to 5n in 4n to 4n are not empty (step 405), the outside line state determination unit 204 determines the return state of the loop current without accessing the station lines 51 to 5n (step 407).

When the loop current returns in the loop current return state, the failure state determination unit 214 determines that there is no failure in each of the station line interface units 41 to 4n (step 408).

Next, the operation of outputting the result report will be described.
