Zenitel IP devices supports Automatic Gain Control (AGC). The purpose of the AGC feature ..............
Default active???
Not config in TCIV+?
Mic Automatic Gain Control
Config Currently only for VSFT/imx28 devices. VSFF/imx6 and imx8 have "Fixed Mic Automatic Gain Control", see below
To be used with caution and in special conditions where Near-End talker may be operating in varying distances deviating from the nominal talker distance to the station.
IC-Edge mode
Log in to the Edge Controller, and navigate to Edge Controller > System Configuration > Call and Audio, and enable "AGC":
SIP and ICX-AlphaCom mode
Log in to the Zenitel IP device.
- SIP mode: Navigate to SIP Configuration > Audio Settings, and enable "Automatic Gain Control (AGC)"
- ICX-AlphaCom mode: Navigate to Advanced ICX-AlphaCom > Audio Settings, and enable "Automatic Gain Control (AGC)"
Some additional settings are available in Advanced Configuration mode. Navigate to Audio Settings > Audio signal processing:
- Enable AGC: AGC component brings the microphone signal to an appropriate range
- AGC mode: Algorithm type
- Digital SW AGC - for the majority of use cases
- Analouge HW AGC (noisy profile) - only available on Turbine devices using analogue microphone. "Analogue HW AGC" should basically be used for "Push to Talk"/"Talk back" applications and not in Open Duplex modes.
- Analouge HW AGC (quiet profile) - only available on Turbine devices using analogue microphone. "Analogue HW AGC" should basically be used for "Push to Talk"/"Talk back" applications and not in Open Duplex modes.
- AGC gain profile: Extent level of added gain
- Standard
- Moderate
- High
- Very high
- AGC speed: Attack time
- Slow
- Fast
For majority of use cases use Digital SW AGC.
The "Analogue HW AGC" is also only available on VSFT devices using analogue microphone.
"Analogue HW AGC" should basically be used for "Push to Talk"/"Talk back" applications and not in Open Duplex modes.
