H.239-Enabled Mih Topology - Polycom RealPresence 1800 Administration Manual

H.239-enabled MIH Topology

Note: Cascading Topology Applicability for Platform
MIH cascading topology is not applicable for Collaboration Server Virtual Edition.
H.239 Multi-Hierarchy (MIH) cascading is available to 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-video, etc.
● Significant call cost savings to be realized by having participants call local MCUs which in turn call
remote MCUs, long distance.
