●If there are insufficient resources to connect all Multiple Cascade Links in either of the RMXs, none
of the links are connected and resources deficiency -0 is listed as the Call Disconnection Cause. For
more information see Monitoring Multiple Cascade Links.
●Multiple Cascade Links that are not used by MLA are inactive but continue to consume resources.
●All RMXs participating in the cascade must have the same Telepresence Mode definitions, either all
defined as CP or all defined as Room Switch.
●When Multiple Cascade Links are defined in the Conference Profile, the Layout Type field of the Link
Participant’s Participant Properties - Media Sources dialog box is set to Conference and cannot be
modified.
●TIP Telepresence Rooms (CTS) are supported without Content. For more information see the
Collaboration With Cisco’s Telepresence Interoperability Protocol (TIP).
Enabling and Using Multiple Cascade Links
The settings required to enable Multiple Cascade Links on the RMX are minimal and are described in
Creating a Link Participant.
Most of the layout configuration is performed using Polycom’s Multipoint Layout Application (MLA).
The figures RMX Telepresence Layout Mode - Room Switch and RMX Telepresence Layout Mode -
Continuous Presence show example layouts and media flows when MLA is configured for a cascading
conference between two RMXs.
In the figure RMX Telepresence Layout Mode - Room Switch:
●The OTX Room System connects to RMX A.
●The RPX Room System connects to RMX B.
●This layout requires that the Telepresence Layout Mode to be set to Room Switch in the Conference
Profiles of the Cascading Conferences in each RMX.
●The current speaker is a participant in the RPX ITP Room.
