Flag Settings

Setting the Maximum CP Resolution for Conferencing
The MAX_CP_RESOLUTION flag value is applied to the system during First-time Power-up
and after a system upgrade. The default value is HD1080.
All subsequent changes to the Maximum CP Resolution of the system are made by selections
in the Max CP Resolution pane of the Resolution Configuration dialog box.
Depending on the type of Media card(s) installed, the Maximum CP Resolution of the RMX
can be set to one of the following resolutions:
MPM Cards
HD 720p30
SD 30
SD 15
CIF 30
Minimum Frame Rate Threshold for SD Resolution
The MINIMUM_FRAME_RATE_THRESHOLD_FOR_SD System Flag can be added and
set to prevent low quality, low frame rate video from being sent to endpoints by ensuring
that an SD channel is not opened at frame rates below the specified value. For more
information see "Modifying System Flags" on page 21-1.
H.264 High Profile System Flags (Version 7.0.1 only)
The flags listed below are used in version 7.0.1 only. From Version 7.0.2 these flags were replaced
with the High Profile sliders in the Resolution Configuration dialog box. For more information, see
"Controlling Resource Allocations for Lync Clients Using RTV Video Protocol" on page 3-25.
Setting minimum bit rate thresholds that are lower than the default may affect the video
quality of endpoints that do not support the H.264 High Profile.
Endpoints that do not support H.264 High Profile will connect according to the minimum
bitrate thresholds defined by the following System Flags:
•

•
3-22
HD 720p30 resolution will instead connect at SD 30 resolution. Each of the affected
endpoints will connect at lower resolution but will use less video resources.
Moving the HD1080p30 resolution slider from 4096kbps to 2560kbps decreases the
minimum connection threshold line rate for that resolution. Endpoints connecting at
line rates between 2560kbps and 4096kbps that would have connected at
HD 720p30 resolution will instead connect at HD 1080p30 resolution. Each of the
affected endpoints will connect at higher resolution but will use more video resources.
