*'''Enable AVC''': Check the box to enable automatic volume control. Volume is adjusted according to the ambient noise level. The AVC will perform better if the loudspeaker volume is set to a fairly low level, as this will give the AVC a more dynamic range for adjustments. Note that the AVC adjustment is disabled while the speaker is playing audio. Adjustments are made in silent periods (min. 100 ms silence required).

** '''Hysteresis''': Hysteresis around previous set ambient audio level before doing adjustments. Range: 1..10 dBA/sec. Default is 3 dBA.
 
−
** '''Far-End Lockout Time''': When playing audio in AVC zone (far-end-signal) AVC adjustments are locked. When there is a pause in the far-end-signal, adjustment commences after this lockout-time. Range: 1..100. Resolution is 100 ms. Default is "1" (= 100 ms).

Zenitel IP devices supports Automatic Gain Control (AGC). The purpose of the AGC feature ..............


Default active???

Not config in TCIV+?


IC-Edge mode

Log in to the Edge Controller, and navigate to Edge Controller > System Configuration > Call and Audio, and enable "AGC":

Enabling AGC in an IC-Edge system



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: Check the box to enable automatic volume control. Volume is adjusted according to the ambient noise level. The AVC will perform better if the loudspeaker volume is set to a fairly low level, as this will give the AVC a more dynamic range for adjustments. Note that the AVC adjustment is disabled while the speaker is playing audio. Adjustments are made in silent periods (min. 100 ms silence required).
  • Debug in Display: When enabled the station shows current volume level in the OLED display (applicable to TCIS-4, TCIx-5 and TCIx-6 stations)
  • AGC mode: Check to open for more advanced AVC settings
  • AGC gain profile: Threshold level for the AVC to start working. Valid range: 30-80 dBA. Default is 55 dBA.
    • AGC speed: Threshold level for the AVC to stop working. Valid range: 60-120 dBA. Default is 100 dBA.
