RMX 1500/2000/4000 ISDN – E1/T1 Connection Capacity vs. Bit rate

Bit Rates	Number of Participants per RTM ISDN Card
(Kbps)
	E1	T1	Type
(Bonded)
64	120	92	Voice / PSTN
128	40	40
192	40	40
256	40	40
320	40	40
384	34	34
512	25	25	Video
768	17	17
1152	11	11
1472	9	9
1536	8	8
1920	7	6

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.
