TCP Port from_to_ These fields display the default settings for port numbers used for
signaling and control. To modify the number of TCP ports, enter the first and last port numbers
in the range. The number of ports is calculated as follows: Number of simultaneous calls x 2
ports (1 signaling + 1 control).
UDP Port from_to_ These fields display the default settings for port numbers used for audio
and video.
To modify the number of UDP ports in Card Configuration Mode, enter the first and last port
numbers in the range. The number of ports is calculated as follows:
Number of simultaneous calls x 8 ports (2 audio, 2 video, 2 Content, and 2 FECC).
To modify the number of UDP ports in MPM+/MPMx Card Configuration Mode, enter the first
and last port numbers in the range, and the range must be 1024 ports. When ICE
environment is enabled, the range must be 2048 ports.
Caution: Specifying Port Ranges
If you do not specify an adequate port range, the system accepts the settings and issues a
warning. Calls are rejected when the MCU's ports are exceeded.
Configure QoS Settings
This section shows you how to configure Quality of Service (QoS) settings in the RealPresence
Collaboration Server (RMX) Management pane. QoS is important when transmitting high bandwidth audio
and video information. The following QoS features can be measured and guaranteed:
Average delay between packets
Variation in delay (jitter)
Transmission error rate
The RealPresence Collaboration Server (RMX) system supports two QoS methods: DiffServ and IP
Precedence. Each method uses a different way to encode packet priority in the packet header. The
RealPresence Collaboration Server (RMX) system implements QoS per Network Service, not per
endpoint.
Note: The Routers Must Support QoS
Note that the routers must support QoS to allow IP packets to get higher priority.
To configure QoS settings:
1 In the RMX Management pane, click QoS.
The QoS settings display, as shown next.
