Comprise SLIC test module, utilizing newly-increased line test function, for simulating the test of PCM4, after PCM4 has tested, test result being sent to TIU module.

A kind of PCM4 method of testing, comprises the following steps:

Step one, utilizes AGENT module to receive and resolves test platform and send test command, issues initial data in test command to TIU module;

Step 2, TIU module selects corresponding PCM4 test set according to initial data, and PCM4 test set is sent to SLIC test module in order;

Step 3, SLIC test module is tested according to test set is incompatible, and test set includes the test case of PCM4, after set to be tested completes, test result is fed back to TIU module;

Step 4, the matching test set of TIU module and test result, and test result corresponding for test command is sent to AGENT module;

Step 5, AGENT module judges that whether the initial data of the test that SLIC test module returns is consistent with template data, is labeled as failure, judged result and original test data is sent to test platform simultaneously for the test event exceeding threshold value.

In the present invention:

AGENT module is proxy module, is responsible for mutual between platform and system;

SLIC test module is speech line test module, is responsible for the line characteristic of tested speech;

TIU module is line test adaptation module, is responsible for the selection of test event, the adaptation of line test

PCM4 is the transmission objective test of user interface, includes transmission level, loss frequency distortion, idle noise, group delay, group delay distortion, the multinomial test such as cross-talk.

The beneficial effect adopting technique scheme to produce is:

1, by expanding SLIC line test function, by the method for SLIC line test, the test template of simulation PCM4 tester, tests the transmission objective of user interface.
