DMA OperationsGuide Conference Templates
198 Polycom, Inc.
On the Conference IVR tab of the Add Conference Template and Edit
Conference Template dialog boxes, the list contains the names of all the
conference IVR services available on the currently connected MCUs. If an IVR
service is only available on some of the connected MCUs, its entry shows how
many of the MCUs have that IVR service (for instance, 2 of 3).
If a template specifies a conference IVR service, the system will put
conferences using that template on the least used RMX MCU that has that
conference IVR service. If there are none, it falls back to the default conference
IVR service.

About Cascading One of the conference features you can optionally enable in a template is
cascading, which makes it possible for a conference to span RMX MCUs.
Cascading a conference across multiple MCUs can conserve bandwidth and is
especially useful when using WAN links. Participants can connect to MCUs
that are geographically near them, reducing network traffic between sites to a
single link to each MCU.
Cascading does, however, impact the quality of the conference experience.
If you have a Polycom RealPresence Resource Manager or CMA system in
your network, you can enable cascaded conferences with these steps:
1On the Polycom RealPresence Resource Manager or CMA system, create
site topology data defining the territories, sites, site links, and MPLS
clouds in your network, and the subnets in each site.
2On the Polycom DMA system, integrate with the Polycom RealPresence
Resource Manager or CMA system to obtain its site topology data. See
“Resource Management System Integration” on page 185.
Note
The cascade links between RMX MCUs must use H.323 signaling. For conferences
with cascading enabled, the Polycom DMA system selects only MCUs that have
H.323 signaling enabled.
This cascade link requirement doesn’t affect endpoints, which may dial in using SIP
(assuming the MCUs and the Polycom DMA system are also configured for SIP
signaling).
