PURPOSE:To block automatically a faulty test device by supervising a response time of the result of test to the fault of the test device in the maintenance test system of a voice or data exchange. CONSTITUTION:When a maintenance personnel inputs a test request command from an input/output device 4, a test controller 2A is started via a central processing unit 3, the test controller edits the result of test by test devices 11-1n, returns it to the central processing unit 3, which outputs the result of test to the input/output device 4. The test controller 2A supervises the required time of the test device and if no command is received from the test device even after a required time is elapsed, retrial is conducted for a prescribed number of times, then a test device fault is informed to the input/output device 4 via the central processing unit and the test device is disconnected from the system and blocked. |
