Above-mentioned noise takes place and injection device 4 comprises noise generator and noise injector, and wherein noise generator is the DLS5500 of Spirent company, and the noise injector is the DLS5405 of Spirent company.
Method of testing of the present invention in the specific implementation, concrete steps are:
Step S1: the tester connects testing equipment, begins to carry out;
Step S2: test item and relevant information that the tester carries out needs are configured;
Step S3: program is according to tester's configuration, and whether the testing equipment that judgement needs connects normally, if connect normally, the then relevant log information of opening entry, and entering step S4 if malunion is normal, then gets into step S21;
Step S4: take out a test item in turn, the equipment that this test item of initialization need be used;
Step S5: take out the test subitem in the current test item in turn, and obtain noise and distance that this test subitem need add;
Step S6: control circuit emulating instrument 3 simulates corresponding circuit types and distance according to the requirement of test subitem, is called for short to add apart from operation;
Step S7: judge to add success,, then change step S8 over to,, and change step S9 over to if success then will add apart from the frequency of failure continuously and be changed to 0 if unsuccessful apart from whether;
Step S8: add after failure, judge the current maximum continuous frequency of failure that whether reaches tolerance apart from the frequency of failure that adds continuously, if do not reach; Then connection is added apart from the frequency of failure and add one; And change step S6 over to and attempt adding distance again, if reached, then change step S21 over to;
Step S9: add after success, the control noise takes place and injection device 4 simulates the noise that needs and is carried in the circuit two ends according to the requirement of testing subitem, is called for short and adds the operation of making an uproar;
Step S10: judge to add the whether success of making an uproar,, then change step S11 over to,, and change step S12 over to if success then will add apart from the frequency of failure continuously and be changed to 0 if unsuccessful;
Step S11: after adding the failure of making an uproar, judge the current maximum continuous the frequency of failure whether frequency of failure of making an uproar reaches tolerance that adds continuously, if do not reach; Then connection is added the frequency of failure of making an uproar and add one; And change step S9 over to and attempt again adding making an uproar, if reached, then change step S21 over to;
Step S12: add apart from the operation and add make an uproar the operation all the success after; In xDSL local side apparatus 1, load the configuration file that the test subitem needs on the used subscriber's line of tested xDSL terminal equipment 2; And restart this circuit, issue launch order in, begin to calculate lock in time;
Step S13: tested xDSL terminal equipment 2 synchronizing informations of inquiry on xDSL local side apparatus 1;
Step S14: whether synchronously the information according to inquiry is returned judge the success of tested xDSL terminal equipment 2, if success then gets into step S15, if unsuccessful, then gets into step S16;
Step S15: after the success, on xDSL local side apparatus 1, extract no-load speed and some other detecting informations that need of tested xDSL terminal equipment 2, and write down lock in time synchronously;
Step S16: if there is not success synchronously, then judge whether to reach the lock in time of maximum,, then change step S13 over to,, then change step S17 over to if reached maximum lock in time if be less than;
Step S17: after the lock in time that reaches maximum, xDSL terminal equipment 2 to be measured does not all have success synchronously, and then the test result with current subitem is recorded as NotLink, or other are used to identify the object information of this kind state;
Step S18: behind Pretesting subitem EOT, judge whether this test subitem is last subitem of current test item, if, then change step S19 over to, if not, then change step S5 over to;
Step S19: if work as the Pretesting subitem is last subitem of current test item; Representing that current test item has been tested finishes; During then the test result of this test item records; And according to testing standard the data of this test item are judged, provide a conclusion of whether passing through and record in the Excel form;
Step S20: behind the current test item EOT, judge whether this test item is last test item of whole content measurement, if, then change step S22 over to, if not, then change step S4 over to;
Step S21: break down if detected tester in the test process, then return the instrument failure mistake, and finish test;
Step S22: after all content measurements were all tested and finished, disconnection was connected with each testing equipment, stops log information, and generated test report, finished test.
