Chapter 4 - Hardware Description
4-60
The maximum transmission capability of E1 lines (up to 1920 Kbps) can be
used in Transcoding or Continuous Presence conferences. To enable the high
line rate transmission, a newer video card version (version 1.43 and up) must
be installed.
Figure 4-12 describes the various video card versions and their support of 30
frames per second and high bit rate:
If the High Bit Rate flag is set to Yes, and the MCU contains video cards of a
version older than 1.43, the MCU status changes to Major and an appropriate
error message is added to the Faults log. In such a case, the highest line rate
that can be set for the conference is 768 Kbps. If the High Bit Rate flag is set
to No, the high bit rate option is disabled and the highest conference rate is
limited to 768 Kbps.
Video+ Module
The Video+ module supports up to 8 participants per module. In addition
it provides the following features/enhancements:
• Click&View - A graphical console transmitted to endpoints enabling
the users to change their personalized video layout or conference.
• Personal Layout - Definition and on-the-fly modification of
individualized participant Continuous Presence layouts. For details,
see Personal Layout
• Visual Effects - Definition of background colors, frame colors and
frame widths for Continuous Presence layouts. For details, see Visual
Effects
