Disabling/enabling automatic gain control
Use the following procedure to turn automatic gain control for the handset, headset,
and/or the Speaker on or off.
Note:
When updating local (Craft) procedures from a touchscreen deskphone, touching
the line you want to change or the applicable softkey produces the same result
as selecting a line and pressing the applicable softkey on a non-touchscreen IP
Deskphone.
Note:
The user can potentially override the AGC local procedure settings, as described
in the telephone user guide. If overridden, the backup file stores the AGC value(s)
set by the user and ignores any setting established using this local procedure.
1. When you select AGC from the Craft Local Procedure Screen, the following text
displays:
Handset Automatic Gain control On
Headset Auto Gain Control On
Speaker Auto Gain Control On
where the setting is the text string associated with the current system value of
NVAGCHAND, NVAGCHEAD, or NVAGCSPKR, defined as:
• “On” if the respective NVAGCXXXX system value is “1”.
• Off if the respective NVAGCXXXX system value is “0”.
