Defining the Cascade Enabled Entry Queue on the RMX
If the dialing is done from the conference running on the MGC that is the Master MCU, a
Cascade-enabled Entry Queue must be defined on the RMX setting it as Slave.
For more details, see RMX to RMX Cascading.
Defining the Cascading Conferences
The table below lists the line rates and the video settings that should be used when defining
the conferences on the MGC. The same line rates should be selected when defining the
Conference Profiles on the RMX, as well as whether the conference is HD Video Switching.
However, the video settings will be automatically selected by the system.

In addition, the conference running on the MGC should be set as Meet Me Per Conference
and select the H.239 option in the Dual Stream Mode field. For more details on conference
definition on the MGC, refer to the MGC Manager User's Guide, Volume I, Chapter 5.
Defining the Dial-out Participant on the RMX
If the dialing is done from a conference running on the RMX to the conference running on
the MGC, the dial-out participant is defined in the conference running on the RMX, setting
the Cascade field to Slave. This participant dials the Cascade-enabled Entry Queue defined
on the MGC.
