3 Select the MCU of interest and click Edit .
4 Complete the Identification, Addresses, Capabilities, MCU Services,
MCU Resources, and MCU Cascading sections of the Edit Device dialog
box. (For more information, see “View Device Details” on page 227.) At a
minimum, assign the MCU a System Name.

Enable Cascading Conferences on Polycom MCUs
To enable multi-bridge conferences, you must complete the following steps:
1 Configure entry queues on the participating MCUs. Only bridges with
entry queues are displayed in the list of available bridges to schedule on
the people-to-bridge or bridge-to-bridge scheduling page.
To configure cascading using a Polycom RMX MCU, you must create two
cascading entry queues—one for which the Master option on the Cascade
menu is selected and one for which the Slave option on the Cascade menu
is selected. Also, enable the Use Entry Queue selection.
The primary purpose for the Master and Slave designation is to determine
which Polycom RMX MCU is responsible for managing People + Content
for the conference.
2 Configure MCU Cascading for each MCU on the CMA system by editing
each MCU and referencing the appropriate entry queue ID and ISDN
numbers.
Some notes about cascading MCUs:
• A Polycom RMX 1000 MCU cannot be used for cascading.
• All devices (MCUs and endpoints) in a cascaded conference must be
registered to the same CMA system gatekeeper.
• All systems (the CMA system, MCUs, and endpoints) must be time
synchronized.
• Since ISDN cascade links on Polycom RMX MCUs are not supported, do
not select Enable ISDN/PSTN Access. The CMA system only supports
cascaded IP links on Polycom RMX MCUs. It does not support cascaded
ISDN links on Polycom RMX MCUs.
• Polycom RMX systems enforce a 1x1 layout for the cascaded link between
bridges, so only one participant on each bridge is displayed at any time.
To change this on a Polycom RMX system, go to Setup > System
Configuration and on the MCMS_PARAMETERS_USER page add a
new flag called
FORCE_1X1_LAYOUT_ON_CASCADED_LINK_CONNECTION
with a Value of
NO
