Setting up MIH Cascading Conferences
The cascading topology, the master/slave relationship and the dialing direction determines
the set-up procedure:
• RMX to RMX
• MGC to RMX
• MGC to MGC
For more details about the MGC to MGC connection, see the MGC Manager User’s Guide,
Volume II, Chapter 1, “Ad Hoc Auto Cascading and Cascading Links”.
RMX to RMX Cascading
Level 1 (Master)
Figure 4-5 Dialing Direction
Level 2 (Slave to Level 1)
To establish the links between two RMXs requires the following procedures be performed:
• Establish the Master-Slave relationships between the cascaded conferences by defining
the dialing direction.
• Create the Master and Slave conferences, defining the appropriate line rate and whether
it is a CP conference or HD Video Switching conference.
• Create a cascade-enabled Entry Queue for dial-in connections (you create it once for all
cascading links using the same line rate).
• Create a cascade-enabled Dial-out Participant link in the Master or the Slave conference
(depending on the dialing direction).
Establish the Master-Slave relationships and the dialing direction
MIH Cascading conferences are linked in a master-slave relationship with each other
according to the dialing direction. It determines the definition of the cascaded links and the
Entry Queues. Dialing directions can be top-down or bottom-up or up from level 4 to level 3
and from level 3 to level 2 and down from level 1 to level 2.
It is recommended to select one dialing direction (usually bottom up) for the entire hierarchy to
simplify the setup procedure.
