Contents Introduction
xConfiguration Conference [1..1] MaxTotalTransmitCallRate
This configuration applies when using a video system's built-in MultiSite feature (optional) to host a
multipoint video conference.
Specify the maximum overall transmit bit rate allowed. The bit rate will be divided fairly among all
active calls at any time. This means that the individual calls will be up-speeded or down-speeded as
appropriate when someone leaves or enters a multipoint conference, or when a call is put on hold
(suspended) or resumed.
The maximum transmit bit rate for each individual call is defined in the Conference
MaxTransmitCallRate setting.
Requires user role: ADMIN
Value space: <64..10000>
Range: Select a value between 64 and 10000.
Example: xConfiguration Conference 1 MaxTotalTransmitCallRate: 10000
xConfiguration Conference [1..1] MaxTotalReceiveCallRate
This configuration applies when using a video system's built-in MultiSite feature (optional) to host a
multipoint video conference.
Specify the maximum overall receive bit rate allowed. The bit rate will be divided fairly among all
active calls at any time. This means that the individual calls will be up-speeded or down-speeded as
appropriate when someone leaves or enters a multipoint conference, or when a call is put on hold
(suspended) or resumed.
The maximum receive bit rate for each individual call is defined in the Conference
MaxReceiveCallRate setting.
Requires user role: ADMIN
Value space: <64..10000>
Range: Select a value between 64 and 10000.
Example: xConfiguration Conference 1 MaxTotalReceiveCallRate: 10000
xConfiguration Conference [1..1] VideoBandwidth Mode
Set the conference video bandwidth mode.
Requires user role: ADMIN
Value space: <Dynamic/Static>
Dynamic: The available transmit bandwidth for the video channels are distributed among the
currently active channels. If there is no presentation, the main video channels will use the
bandwidth of the presentation channel.
Static: The available transmit bandwidth is assigned to each video channel, even if it is not active.
Example: xConfiguration Conference 1 VideoBandwidth Mode: Dynamic

xCommand
The available transmit video bandwidth is distributed on the main channel and presentation channel
according to "MainChannel Weight" and "PresentationChannel Weight". If the main channel
weight is 2 and the presentation channel weight is 1, then the main channel will use twice as much
bandwidth as the presentation channel.
Requires user role: ADMIN
Value space: <1..10>
Range: 1 to 10.
Example: xConfiguration Conference 1 VideoBandwidth MainChannel Weight: 5
The available transmit video bandwidth is distributed on the main channel and presentation channel
according to "MainChannel Weight" and "PresentationChannel Weight". If the main channel
weight is 2 and the presentation channel weight is 1, then the main channel will use twice as much
bandwidth as the presentation channel.
Requires user role: ADMIN
Value space: <1..10>
Range: 1 to 10.
Example: xConfiguration Conference 1 VideoBandwidth PresentationChannel Weight: 5
This configuration applies to video systems that are using the built-in MultiSite feature (optional) to
host a multipoint video conference. When a remote user shares a presentation, the video system
(codec) will transcode the presentation and send it to the other participants in the multipoint
conference. The RelayQuality setting specifies whether to give priority to high frame rate or to high
resolution for the presentation source.
Requires user role: ADMIN
Value space: <Motion/Sharpness>
Motion: Gives the highest possible frame rate. Used when there is a need for higher frame rates,
typically when there is a lot of motion in the picture.
Sharpness: Gives the highest possible resolution. Used when you want the highest quality of
detailed images and graphics.
Example: xConfiguration Conference 1 Presentation RelayQuality: Sharpness
