Cascading Conferences - Polycom RMX 2000 Administrator's Manual

Cascading Conferences

Cascading enables administrators to connect one conference directly to
another conference using an H.323 connection. The conferences can run
on the same MCU or different MCUs. There are many reasons for
cascading conferences, the most common are:
• Connecting two 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....
The link between the two conferences is created when a participant that is
defined as a dial-out cascaded link in one conference (Conference A)
connects to the second conference (Conference B) via a special cascaded
Entry Queue (EQ). When MCU A dials out to the cascaded link to connect
it to conference A, it actually dials out to the cascaded Entry Queue
defined on MCU B.

Though the process of cascading conferences mentioned in this section
refers to conferences running on two different RMX units, it is possible to
cascade conferences running between RMX units and other MCUs.
When cascading two conferences, the video layout displayed in the
cascaded conference is determined by the selected layout in each of the
two conferences. Each of the two conferences will inherit the video layout
of the other conference in one of their windows.
