Troubleshooting the Avaya XT Series
The link quality indicator level is evaluated separately for audio, video, and presentation streams,
based on the average packet loss percentage of the last five seconds. The worst of the three
calculated levels is then displayed.

Icon
For example, if the overall link quality indicator level is Excellent, it means that the average packet
loss is now less than 3% for audio, 1% for video, and 1% for presentation.
Procedure
• In a point to point call, the link quality indicator level is displayed in the XT Series user
interface top header. If the level is Normal or below, it is also displayed as an alert over the
video, when the top header is not visible.
• In a multipoint call hosted by the XT Series built-in MCU, the link quality indicator level is
displayed as overlay image on the remote participants' video. The level is also available in
the statistics of each active call.
