Cascading Conferences - H.239-enabled MIH Topology

H.239 Multi-Hierarchy (MIH) cascading is available to RealPresence Collaboration Server users enabling
them to run very large conferences on different MCUs in multiple levels of Master-Slave relationships using
an H.323 connection.
Multi-Hierarchy (MIH) Cascading is implemented where the cascaded MCUs reside on different networks,
whereas Star Topology Cascading requires that all cascaded MCUs reside on the same network.
MIH Cascading allows:
● Opening and using a content channel (H.239) during conferences.
● Full management of extremely large, distributed conferences.
● Connecting conferences on different MCUs at different sites.
● Utilizing the connection abilities of different MCUs, for example, different communication protocols,
such as, serial connections, ISDN, etc.
● Significant call cost savings to be realized by having participants call local MCUs which in turn call
remote MCUs, long distance.
