Individual or Batch Distortion/Echo Test

This test takes approximately 15 minutes to complete on each trunk. While the test is running on a trunk, the system takes the trunk out of service.

CAUTION: Only run this test at the request of Mitel Technical Support. System performance could be degraded while the test is running.

To run the tests

  1. Ensure that you have configured the system to support testing. See

  2. Configure System for Testing_using_Central_Office_Numbers

  3. Configure System for Testing_using_Loopback

  1. Access the Line Quality Measurement form.

  2. Click Run Test.

  3. Select the Test Type. To test a single trunk select Individual Distortion/Echo then select the PLID of the trunk. To run the test on all the eligible LS trunks in the system, select Batch Distortion/Echo.  The PLID field is disabled.

  1. If the test is successful, the test results are saved in the "/db/database/LSMeasure" directory. If the test fails, an error message is displayed. See Error Messages.
