The following table summarizes Video Session Modes line rate options that need to be
selected for each conference in the cascading hierarchy according to the cascading topology:

Creating a Cascade Enabled Dial-out/Dial-in Participant Link
The connection between two cascaded conferences is established by a cascade enabled dial-
out and dial-in participants, acting as a cascades link.
The dialing direction determines whether the dial-out participant is defined in the
conference running on the Master MCU or the Slave MCU. For example, if the dialing
direction is from the Master conference on level 1 to the Slave conference on level 2, the dial-
out participant is defined in the Master conference on level 1 and a dial-in participant is
defined in the Slave conference running on the MCU on level 2.
If the cascade-enabled dial-out participant always connects to the same destination
conference on the other (second) MCU, the participant properties can be saved in the
Address Book of the MCU for future repeated use of the cascaded link.
To define the dial-out cascade participant link:

When creating a cascading link between two RMXs:
— The RMXs operate in CP (Continuous Presence) mode.
When creating a cascading link between MGCs and RMXs:
— The MGCs can only operate in VSW mode.
