RMX Resource Management by CMA and DMA

Table 19-14 lists the ISDN supported bit rates and their respective
participant connection capacities per RTM ISDN card:

When both CMA and DMA are part of the solution, following a request by
the CMA and DMA, the RMX will send updates on resource usage to both
CMA and DMA, with each application updating its own resource usage
for the RMX. This provides better management of the RMX resources by
CMA and DMA.
Guidelines
• Resource usage updates from RMX to the CMA and DMA are
supported only with RMXs with MPM+ or MPMx cards.
• Both Flexible Resource Capacity™ and Fixed Resource Capacity™ modes
are supported with DMA.

Number of Participants
per RTM ISDN Card
T1
40 If the conference bit rate is 128Kbps,
participants connecting at bit rates
40
lower than 128Kbps are
disconnected.
40
40 If the conference bit rate is above
128Kbps but does not match any of
34
the bonded bit rates, participants are
connected at the highest bonded bit
25
rate that is less than the conference
bit rate.
17
For example: If the conference bit
11
rate is 1024Kbps, the participant is
connected at 768Kbps.
