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 2000, as well as whether the conference is HD Video Switching.
However, the video settings will be automatically selected by the system.

Defining the Dial-out Participant on the RMX 2000
If the dialing is done from a conference running on the RMX 2000 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.
