The following table lists the ISDN supported bit rates and their respective participant connection capacities
per RTM ISDN card:
MCU Resource Management by RealPresence Resource Manager
(XMA), Polycom CMA and Polycom RealPresence DMA System
When the RealPresence Resource Manager (XMA), Polycom CMA and Polycom RealPresence DMA
system are part of the solution, following a request by the RealPresence Resource Manager (XMA),
Polycom CMA or Polycom RealPresence DMA system, the MCU will send updates on resource usage to
both CMA and DMA, with each application updating its own resource usage for the MCU. This provides
better management of the Collaboration Server resources by the RealPresence Resource Manager (XMA),
Polycom CMA and Polycom RealPresence DMA system.
Guidelines
Resource usage updates from RMX to the CMA and DMA are supported only with RMXs with MPMx
cards.
Following requests sent by CMA and 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, CMA/DMA receive information about how many Video (CIF) and Audio resources are
occupied per conference or MCU according the request type sent by the CMA and DMA.
Occupied resources are resources that are connected to ongoing conferences. Disconnected
endpoints in an ongoing conference are not counted as occupied resources.
ISDN – E1/T1 Connection Capacity vs. Bit rate
Bit Rates
(Kbps)
(Bonded)
Number of Participants
per RTM ISDN Card
E1 T1
128 40 40 If the conference bit rate is 128Kbps, participants connecting at bit
rates lower than 128Kbps are disconnected.
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.
