Maintenance Manual

Assigned floor: This endpoint's media is being broadcast to all
endpoints in the conference, although it did not request the floor
itself.
This situation can occur if
another endpoint, while chair,
has issued H.243 commands to
make that endpoint the floor.
For more information, refer to
H.243 floor and chair control.
Some media channels encrypted : Displayed if some media
channels are not encrypted.
Cascade link to master, Cascade link from slave: Indicates that
this connection is a cascade link to or from another conference.
Preview Displays a sample still video capture of the participant. Click the picture to update it.
Note that conferences that are
configured to require encryption
do not show previews. Also note
that previews can be disabled on
the Settings > User interface
page (refer to Customizing the
user interface).
Controls
These controls are only available if the conference is configured
with content enabled, and if the participant is contributing a main
video channel.
This control causes the MCU to attempt to use the
participant's main video channel as the conference's content
channel source. This will not be possible if the conference
already has an active content channel source (either an
endpoint's content video channel or another participant's main
video activated via this control).
This control causes the MCU to stop attempting to use the
participant's main video channel as the conference's content
channel source. It is necessary to use this control to switch to
using a different endpoint's primary video channel or to enable
content video contribution from endpoints.
See Content channel video
support for additional information
on H.239 and BFCP.
All-Participant Controls
Although you may use the controls described above to manage one participant at a time, for example to mute that
participant's audio, or to make them important, you may want to manage all participants at once. The all-participant
controls permit you to do this. Note that you may continue to use the per-participant controls in conjunction with the
all-participant controls. Refer to the table below for details of the controls available:
