Room Switch Telepresence Layouts
The Room Switch Telepresence layouts normally controlled by the MLA can be managed by the MCU to
speed updating the conference layouts in large conferences with many endpoints.
Whether the MLA or the MCU controls the Room Switch Telepresence layouts is determined by the
MANAGE_TELEPRESENCE_ROOM_SWITCH_LAYOUTS flag. This flag must be manually added before
changing its value. No system reset is required.
The values are:
● NO (Default) - The MCU does not manage Telepresence Room Switch Layouts and they continue to
be managed by the MLA.
● YES - The MCU manages Telepresence Room Switch Layouts.
When the MCU controls the Telepresence Room Switch layouts
(MANAGE_TELEPRESENCE_ROOM_SWITCH_LAYOUTS = YES) the display is affected according to
the Telepresence Mode Settings in the Conference Profile as follows:
● If the Telepresence Mode = ON
If no ITP endpoints are connected to the conference, the RMX Room Switch layout applies, in
which case only the speaker is seen.
When a single participant using an ITP endpoint with either single or multiple screens connects to
the conference, the participant will see black screens.
● If the Telepresence Mode = AUTO
If no ITP endpoints are connected to the conference, the RMX CP layout applies (unless the
conference layout is defined).
When a single participant using an ITP endpoint with multiple screens connects to the conference,
the participant will see black screens.
When a single participant using an ITP endpoint with a single screen connects to the conference,
the MCU will display a self-view of the participant.
● When a TIP system with 3 screens joins a conference, the layout is updated on all screen
simultaneously.
● When a Polycom ITP system with 2, 3, or 4 screens joins the conference, the layout is updated on all
screens simultaneously.
Telepresence Display Decision Matrix
How the speaker video is displayed on the screens of the conference participants is dependent on the
relationship between the number of screens the speaker endpoint contains and the number of screens of
the endpoints of the other conference participants.
