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.
