Resource Management
This section describes how the MCU resources are managed by the MCU and how they are used by the
MCU to connect participant to conferences.
This section describes:
● Resource Capacity
● Flexible Resource Capacity

● MCU Resource Management by RealPresence Resource Manager, Polycom CMA and Polycom
RealPresence DMA System
Resource Capacity
The MCU resources are determined by the MCU type, Card Configuration Mode and the system license you
have purchased. The total number of licensed resources is shown in the System Information.
Collaboration Server (RMX) 2000 can include up to two media cards and Collaboration Server (RMX) 4000
can include up to four media cards. Both include one RTM-ISDN card with up to 7 E1 or 9 T1 connections.
Collaboration Server (RMX) 1800 does not contain any MPM media cards, yet it supports one media card
type similar to the MPMRx card, and therefore has similar capabilities (in terms of the media card).
Collaboration Servers 1800 with 3 DSP cards and built in ISDN also support up to 4 ISDN/PSTN E1/T1
connections.
Collaboration Server (RMX) 1800 with no DSP cards does not contain DSP cards.
In AVC CP Conferencing video resources usage varies according to the video resolution used by the
endpoints. The higher the video resolution (quality), the greater the amount of video resources consumed
by the MCU.
For more information about Resource Capacities, see the RealPresence® Collaboration Server (RMX)
Hardware Guide specific to your system.
Resource Usage in AVC CP Conferencing
Video resources usage varies according to the video resolution used by the endpoints. The higher the video
resolution (quality), the greater the amount of video resources consumed by the MCU.
AVC Conferencing - Video Switching Resource Capacity
During a Video Switching conference, each endpoint uses one video (CIF) port.
Resource Usage in SVC Conferencing
During a SVC conference, each SVC-endpoint uses a video port that is equivalent to a third of HD720p30
port. When sharing content an additional video resource is used.
MCUs with 500MB of memory can support a maximum of 400 simultaneous participant calls,
regardless of how system resources are allocated.
MCUs with 1000MB of memory are not subject to this limitation.
MCU memory size is listed in the Administration > System Information properties box. For more
information see System Information.
