Cascading Conferences - H.239-enabled MIH Topology
H.239 Multi-Hierarchy (MIH) cascading is available to RMX 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.
