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.
