Polycom RealPresence Collaboration Server (RMX) 1500/2000/4000

Set this flag to NO when cascading between an RMX and an MGC that is functioning as a Gateway, if the participant layouts on the MGC are not to be forced to 1X1.

•Setting the AVOID_VIDEO_LOOP_BACK_IN_CASCADE System Flag to YES (default) prevents the speaker’s image from being sent back through the participant link from the cascaded conference. This can occur in cascaded conferences with conference layouts other than 1x1. It results in the speaker’s own video image being displayed in the speaker’s video layout.

This option is supported with:

—In H.323, SIP and ISDN environments.

—For Basic Cascading of Continuous Presence and Video Switched conferences. If a Master MCU has two slave MCUs, participants connected to the slave MCUs will not receive video from each other.

—Video resolution will be according to the Resolution Configuration, or VSW profile. For more details on defining system flags, see "Modifying System Flags” on page 22-1.

MGC to RMX Cascading

Level 1 (Master)

Level 2 (Slave to Level 1)

If MGC is running version 9.0.4, and RMX is running version 7.0.2 and higher, the RMX can be set as Master on level 1 and MGC as Slave on level 2.

MGC running versions other than 9.0.4 is always on level 1 and must be set as the Master MCU.

If the cascading topology includes additional MGCs as well as RMXs it is recommended to define Video Switching conferences for all the cascading conferences running on the MGC in the topology.

Two methods can be used to create the Cascading links between conferences running on the RMX and MGC:

•Method I - Establish the links by defining a dial-in and a dial-out participant in the Slave and Master conference (where the Master conference is created on the MCU on Level 1 and the Slave conference is created on the MCU on Level 2).

•Method II - Using a Cascading Entry Queue on either the MGC or the RMX depending on the dialing direction and the MCU Level. This is recommended when the RMX is on Level 1.
