Cascading Conferences - Polycom RMX 1500 Administrator's Manual

Cascading Conferences

Video Layout in Cascading conferences
Cascading enables administrators to connect one conference directly to
one or several conferences, depending on the topology, creating one large
conference. 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 following cascading topologies are available for cascading:
• Basic Cascading - only two conferences are connected (usually
running on two different RMXs). The cascaded MCUs reside on the
same network.
• Star Cascading - one or several conferences are connected to one
master conference. Conferences are usually running on separate
MCUs. The cascaded MCUs reside on the same network.
• MIH (Multi-Hierarchy) Cascading - several conferences are
connected to each other in Master-Slave relationship. The cascaded
MCUs can reside on different networks.
System configuration and feature availability change according to the
selected cascading topology.
Cascade links are treated as endpoints in CP conferences and are allocated
resources according to Table 2-2 on page 2-8. Cascaded links in 1x1 video
layout are in SD resolution.
