Conference Templates  Conference Manager Configuration
Polycom, Inc.  183
3On the Polycom DMA system, enable cascading in some or all of your 
conference templates. 
If you don’t have a Polycom RealPresence Resource Manager or CMA system, 
you must define your site topology in the Polycom DMA system instead of 
importing it. See “Site Topology” on page 263. 
Once a conference with cascading enabled has started (the “hub” MCU has 
been chosen), the Polycom DMA system uses the site topology information to 
route additional callers to the nearest eligible MCU (based on pools and pool 
orders): 
•If the caller is in a site that contains one or more MCUs, the system selects 
an MCU in that site that has available capacity. 
•If the caller is in a site that doesn’t contain MCUs, the system looks for 
MCUs in directly-connected sites (that is, sites that have a network path to 
the caller’s site without going through a cloud) and selects one that has 
available capacity. 
If the selected MCU is new to the conference, the DMA system creates the 
cascade link to the “hub” MCU hosting the conference.

Conference Templates List The following table describes the fields in the Conference Templates list. 
Note 
Cascading always uses a hub-and-spoke configuration so that each cascaded 
MCU is only one link away from the “hub” MCU, which hosts the conference. To 
host the conference, the system chooses the same MCU that it would have chosen 
in the absence of cascading. See “MCU Pool Orders” on page 141.
