RTCP_MONITOR Configuration Syntax

Prognosis for Unified Communications only

This is an optional configuration that can be used to setup the initial call QoS (Quality of Service) levels for MOS (Mean Opinion Score), Latency, Jitter and Packet Loss. This configuration should only be changed if your QoS criteria is different to the default settings.

SUBSYS RTCP_MONITOR
DEFINE MOS_PROFILE (#GlobalDefault, Good=4.0, Fair=3.6, Poor=3.0
DEFINE LATENCY_PROFILE (#GlobalDefault, Good=50, Fair=100, Poor=150)
DEFINE JITTER_PROFILE (#GlobalDefault, Good=20, Fair-=100, Poor=150)
DEFINE PACKETLOSS_PROFILE (#GlobalDefault, Good=1.0, Fair=2.0, Poor=3.0)

Syntax Elements

DEFINE MOS_PROFILE

The MOS is an overall QoS rating which ranges from 0 to 5, the higher the MOS level the better the QoS. The values specified in the configuration profile represent the worst (lowest) value for the rating category. The default setting is:

Good=4.0, Fair=3.6, Poor=3.0

DEFINE LATENCY_PROFILE

Latency refers to the delay in packet delivery in milliseconds. Latency is half of the Round Trip Time (RTT). The lower the Latency the better the QoS. The Configuration profile values specify the worst (highest) value for the rating category. The default setting is:

Good=50, Fair=100, Poor=150

DEFINE JITTER_PROFILE

Jitter is the variation in time (milliseconds) between packets arriving, caused by network congestion, timing drift or route deviation. A Jitter buffer which temporarily stores arriving packets is often used in order to minimize delay variations and Jitter will only affect the QoS once it becomes greater than the Jitter buffer. The lower the Jitter the better the QoS. The profile values specify the worst (highest) value for the rating category. The default setting is:

Good=20, Fair-=100, Poor=150

DEFINE PACKETLOSS_PROFILE

Packet Loss is the percentage of packets lost in transmission.  The lower the Packet loss the better the QoS. The configuration profile values specify the worst (highest) value for the rating category. The default setting is:

Good=1.0, Fair=2.0, Poor=3.0

#GlobalDefault is a special keyword used by Prognosis to denote that this option applies to all configured PBXs. This keyword is a mandatory entry as Prognosis does not support separate MOS, LATENCY, JITTER or PACKETLOSS settings for individual PBXs.
