Cascading
Cascading enables users to run conferences that are distributed among two or
more conferences and MCUs. A participant who dials from one MCU to
another establishes the link between the conferences.
The conferences that are part of a cascading conference may be run:
•on the same MCU, to overcome the maximum number of participants per
conference
•on separate MCUs, to utilize additional resources or connect participants
to their local MCU
In addition, you can enable H.239 People+Content dual stream mode
conferences with H.323 cascading.
For a detailed description of Cascading conference options, see “Defining
Cascading Conferences” in the MGC Manager User’s Guide, Volume II,
Chapter 1, “Advanced Conference Settings”.
For information about H.243 and MIH Cascading conferencing, see the MGC
Manager User’s Guide, Volume II, Chapter 5.
H.243 Chair Control
Chair Control enables an endpoint to control the conference and other
conference participants. This (Chairperson) endpoint that has control over the
conference, can perform the following operations:
•Disconnect participants
•Video Force – select the endpoint to be seen by other participants. Only
one participant can be selected – this participant is displayed in the top
left window
•Terminate the conference
For information about H.243 Chair Control conferences, see the MGC
Manager User’s Guide, Volume II, Chapter 5, “H.243 Chair Control”.
The Highest Common mechanism is disabled in Cascading conferences. When
defining a Cascading conference, all the cascaded conferences must be set to
the same video protocol.
