Conference Template
Voice Switch Timeout
Defines the number of seconds between 1 and 10, a participant
must speak before it gets the speaker indication and is shown as the
speaker to the other endpoints.
A long timeout might be suitable in noisy environments and in confer-
ences with many participants.
Audio Leveling (AGC)
Ensures that all participants will receive the same audio level from all
other participants, regardless of the levels transmitted. AGC - Auto-
matic Gain Control.
In most conferences, the participants will speak at different levels.
As a result, some of the participants are harder to hear than others.
The Audio Leveling corrects this problem by automatically increasing
the microphone levels when “quiet” or “distant” people speak, and by
decreasing the microphone levels when “louder” people speak.
On: When set to On the MCU maintains the audio signal level at a
fixed value by attenuating strong signals and amplifying weak signals.
Very weak signals, i.e. noise alone, will not be amplified.
Off: Set to Off to disable Audio Leveling (AGC).
Far End Telephone Echo Suppression
Analog telephone lines, speaker phones and
telephone headsets may all cause echoes. The
Far End Telephone Echo Suppression function
eliminates some or all of the experienced echo.
Off: Set to Off to disable Far End Telephone Echo
Suppression.
Normal: Set to Normal to remove weak echoes.
High: Set to High to remove strong echoes.
Telephone Noise Suppression
On: Set to On to enable Telephone Noise Suppression. Attenuates
the noise which normally is introduced when adding mobile phones
to a conference. The background noise normally heard when the tele-
phone participant is not speaking will be attenuated.
Off: Set to Onffto disable Telephone Noise Suppression.
Allow G.728
On: The MCU supports high quality audio even
on low call rate. On low call rate the MCU will
prioritize G.722.1. The video participants which do
not support G.722.1 will receive low quality audio
G.728 instead when Allow G.728 is set to On.
Off: To ensure high quality audio on low call rate,
set Allow G.728 to Off. Then video participants
which are not able to support G.722.1, will receive
G.722 instead.

Conference Template Configuration
The Conference Templates are found in the MCU Configuration tab.
The predefined settings will be used as default settings when creating
new conferences based on this specific template. TANDBERG MPS
enables the setup of 10 different conference templates.
The conference template contains the same settings as de-
scribed in the Create Conference in the Overview section.
