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.

Port Consumption Ratios of Different Calls

HD720p30	HD1080p60	HD1080p30	AVC SD	AVC CIF	Audio	SVC
1	4	2	1/2	1/2	1/2	1/3

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.

Port Consumption Ratios, in Mixed Conferences

HD720p30	HD1080p60	HD1080p30	AVC SD	AVC CIF	Audio	SVC
1.5	NA	3	3/4	3/4	3/4	1/3

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.

ISDN/PSTN

RMX 1500 supports one ISDN card with 4 E1/T1 PRI lines. RMX 1800-3 with built-in ISDN supports 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.

E1 and T1 connections cannot be used simultaneously.

The following table lists the ISDN supported bit rates and their respective participant connection capacities per RTM ISDN card:
