H.243 Chair Control
Chair Control enables an endpoint to control the conference and other
conference participants. The endpoint that has control over the conference
(the chairperson) can perform the following operations:
• Disconnect participants
• Video Force – select the endpoint to be seen by the other participants.
Only one participant can be selected. This participant is displayed in the
top left window
• Terminate the conference
These operations are performed by the MCU subsequent to an appropriate
request from the chairperson.
The control over the conference is granted to an endpoint by means of tokens.
An endpoint sends a chair requests to the MCU. The MCU assigns the chair
token to the endpoint requesting it, if no other participant in the conference is
holding the chair token. In the case where another participant is holding the
chair token, the request is rejected by the MCU.
Chair control can be enabled for a conference via the MGC WebCommander
Meeting Scheduler but it can only be managed via the MGC Manager
application. For a detailed description of setting and monitoring
chair-controlled conferences, refer to the MGC Manager User’s Guide.

User’s Guide Volume II, Chapter 4.
LSD - FECC (Far End Camera Control)
(Low Speed Data) Using certain video cameras and their accompanying
software, an ISDN participant may control a far-end camera. The control of
data distribution is accomplished by means of data tokens. The participant
requests the control over a far-end camera (i.e. requests the data token) by
clicking on one of the arrow keys or the zoom keys in the endpoint’s software
application. Upon request, the MCU opens the LSD data channel of all the
conference participants and allocates the data token to the requesting
participant. This allows the participant to transfer commands from one
endpoint to the camera of another endpoint.
