Minimum Threshold Line Rate System Flags
The following table lists the System Flags that control the minimum threshold line rate for the
various resolutions available for High Profile-enabled VSW conferences.
• Line rate and resolution combinations are checked for validity. If the selected line rate is
below the minimum threshold line rate required for the selected resolution, the line rate is
automatically adjusted to the minimum threshold line rate value for the selected resolution.
• The value of the SUPPORT_HIGH_PROFILE System Flag (used for CP conferences)
has no effect on VSW conferences.
• Before they can be modified, all of the System Flags mentioned above must be added to
the system.cfg file using the Collaboration Server Menu – Setup option. For more
information see "Modifying System Flags” on page 22-1.
