If the conference bit rate is above 128Kbps but does not match any of the bonded bit rates, participants are
connected at the highest bonded bit rate that is less than the conference bit rate. For example: If the
conference bit rate is 1024Kbps, the participant is connected at 768Kbps
MCU Resource Management by RealPresence Resource Manager, and

Polycom RealPresence DMA System

When the RealPresence Resource Manager, and Polycom RealPresence DMA system are part of the
solution, following a request by the RealPresence Resource Manager and Polycom RealPresence DMA
system, the MCU will send updates on resource usage to the DMA, which updates its own resource usage
for the MCU. This provides better management of the Collaboration Server resources by the RealPresence
Resource Manager, and Polycom RealPresence DMA system.
Guidelines
● Resource usage updates from RMX to the DMA are supported only for Collaboration Servers with
MPMx card(s).
● Following requests sent by the RealPresence DMA system, the Collaboration Server will send the
number of occupied resources for a conference or total for the MCU.In Flexible Resource Capacity
Mode, the DMA receive information about how many Video (CIF) and Audio resources are occupied
per conference or MCU according the request type sent by the DMA.
● Occupied resources are resources that are connected to ongoing conferences. Disconnected
endpoints in an ongoing conference are not counted as occupied resources.
