Item

 

Description

 

 

 

Min MOS LQK

 

Lowest MOS LQK score observed from start of the voice stream.

 

 

Max MOS LQK

Baseline or highest MOS LQK score observed from start of the voice

 

 

stream.

 

 

These codecs provide the following maximum MOS LQK score under

 

 

normal conditions with no frame loss:

 

 

• G.711 gives 4.5

 

 

• G.729 A /AB gives 3.7

 

 

MOS LQK Version

Version of the Cisco proprietary algorithm used to calculate MOS

 

 

LQK scores.

 

 

Cmltve Conceal Ratio

Total number of concealment frames divided by total number of

 

 

speech frames received from start of the voice stream.

 

 

Interval Conceal Ratio

Ratio of concealment frames to speech frames in preceding 3-second

 

 

interval of active speech. If using voice activity detection (VAD), a

 

 

longer interval might be required to accumulate 3 seconds of active

 

 

speech.

 

 

Max Conceal Ratio

Highest interval concealment ratio from start of the voice stream.

 

 

 

Conceal Secs

 

Number of seconds that have concealment events (lost frames) from

 

 

the start of the voice stream (includes severely concealed seconds).

 

 

Severely Conceal Secs

Number of seconds that have more than 5 percent concealment events

 

 

(lost frames) from the start of the voice stream.

 

 

 

1. When the RTP Control Protocol is disabled, no data generates for this field and thus displays as 0.
