Cascading Topologies
The cascading hierarchy topology should be deployed according to the following
guidelines:
If an RMX is deployed on level 1 (recommended deployment):
Any RMX can be used on level 2, 3 and 4 (recommended deployment),
MGC version 9.0.4 can be used on level 2 and level 3,
DST MCS 4000 and other MCUs can be deployed on levels 3 and 4.
If an MGC is deployed on level 1:
MGC or RMX can be used on level 2,
DST MCS 4000 and other MCUs can be deployed on levels 3 and 4.
DST MCS 4000 MCUs connect as endpoints to the RMXs or MGCs on higher levels.

Master - Slave Conferences
It is recommended to have RMX systems at all levels to leverage the high quality video
and content offered by the RMX.
•In MIH Cascading conferences, although there are multiple levels of Master and Slave
relationships between conferences, the conference that runs on the MCU on level 1 of
the hierarchy must be the Master for the entire cascading session. When an MGC is part
of the cascading topology, it can be configured at any level if MGC Version 9.0.4 is
installed, otherwise, it must be set as Level 1 MCU.
Conferences running on MCUs on levels 2 and 3 and can be both Masters and Slaves to
conferences running on MCUs on levels above and below them.
All conferences running on MCUs on the lowest level in the configuration (for example,
level 3 in a 3-level hierarchy configuration) are Slave conferences.
When the DST MCS 4000 is on level 3 and acting as slave to level 2, the RMX on level 2
must dial out to it in order for the DST MCS 4000 to be identified as slave. The link
between the two MCU (dial out participant) is defined as a standard participant and not
as a cascading link.
