Collaboration Server 2000/4000 Resource Capacity

The Collaboration Server Models 2000/4000 Resource Capacities are set out below.

Resource Capacity in Non-Mixed Conferences

The port consumption ratios of different calls against that of a HD720p30 call are as shown in this table.
In other words, to make one1080p60 call, you need 4x 720p 30 ports; to make one 1080p 30 call, 2x 720p
30 ports; and so forth.
When the required resource is not a whole number, it’s rounded up to the nearest whole number. For
example, to make an SVC call requiring1/3 of an HD720p30 port. However in the Port Gauge, one port
appears allocated.

Resource Capacity in Mixed Conferences

The following table shows the port consumption ratios of different calls against that of an HD720p30 call.
In other words, to make one 1080p30 call, you need 3x 720p30 ports; to make one 720p30 call, 1.5x 720p30
ports; and so forth.
When the required resource is not a whole number, it’s rounded up to the nearest whole number. For
example, to make an SVC call requiring1/3 of an HD720p30 port. However in the Port Gauge, one port
appears allocated.
For more information about resources licenses and capacities for the various Collaboration Server
2000/4000 media card configurations, see the Realpresence Collaboration Server (RMX) 2000 Hardware
Guide and Realpresence Collaboration Server (RMX) 4000 Hardware Guide.
ISDN/PSTN
The RMX 1500 supports one ISDN card with 4 E1/T1 PRI lines.
On the RMX 2000/4000 a maximum of two RTM ISDN cards are supported, each providing connection for
up to either 7 E1 or 9 T1 PRI lines.
On RMX 1500/2000/4000, E1 and T1 connections cannot be used simultaneously.
