higher levels.

MIH Cascading Guidelines

Master and Slave Conferences

•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 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 level 4 are Slave conferences.
• When the DST MCS 4000 is on level 3 and acting as slave to level 2,
the RMX 2000 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.
