SUBSCRIBER'S LINES TEST METHOD

摘要

The on-demand of an operater is executed during subscriber line testing. The method compirses the steps: (A) checking that the subscriber line test instruction is effective; (B) sending error message to an operator when the instruction is ineffective, otherwise storing the instruction on a buffer and sending the instruction acknowledge signal to an operator; (C) comparing test starting time stored in a system with current time; (D) executing the subscriber line testing and checking that the testing is completed; (E) sending the test completion message to an operator and transfering to input stand-by mode when the test is completed, otherwise checking the on-demand signal transmitted from an operator; and (F) quitting the test routine and executing the on-demand.
