Abstract:
A method for locating a failure of a communication line, which includes a network element and a remote test unit connected with a communication network, according to self-adjusted priorities of test points in the order of high failure probability in a communication line management system having a terminal, comprising the steps of:a) organizing the test points, information on a test history of the test points, and test point search priorities (TSPs) representing the priorities of the test points in the order of high failure probability into a test database; b) searching the test database to determined the testing order of the test points according to the TSPs, determining a service type of the communication line and features of the network element and the remote test unit; c) testing the test points in the testing order to locate the failure by using one or more tests selected from a simple test, a dichotomous test and a dichotomous loop-back test; and d) revising values of data fields of the TSPs according to test results and the location of the failure, wherein the simple test is defined as checking a level and resistance of the test point for determining the failure.
