Noisy Line Detection Mechanism and Automatic Muting

Noisy Line Detection Mechanism analyzes the participant’s line signal in order to detect a noisy line and notify the operator. Noise on a participant’s line can be caused by background noise, faulty equipment and noises emanating from the line itself. Noisy Line Detection is enabled and disabled on MCU level in the “system.cfg” by defining the detection sensitivity.

For more details, see the MGC Administrators Guide, Chapter 5.

During an On Going Conference, you can monitor noisy participant lines by selecting the Noisy Line monitor filter. See “Monitor Filter” on page 3-17

When the Noisy Line filter is enabled, the indicating icon	appears in the
Connection column if a noisy line is detected by the system.

In addition, you can enable the SilenceIT option to automatically mute the audio participants who are identified as having a noisy line. SilenceIT uses an algorithm that detects continued background music or other noise that is not in the range of human speech. SilenceIT can be applied to Audio participants in Audio Only and Video conferences. This feature is enabled for conferences with IVR Service, during the conference setup/reservation stage, using the Conference Properties - Settings tab option.

For a detailed description, see Chapter 6, “Using SilenceIT” on page 6-6.
