3.6 Marked Samples
There are several circumstances when voice quality measurement can be affected by factors not directly
related to network performance. Aries provides a mechanism for detecting these bad samples and
excluding them from the analysis. The situations that are detected include:
Call synchronisation lost
Handover in speech sample
Invalid file size
These situations are displayed to the user by an orange ‘Marked’ icon next to the speech sample event as
shown below:
Figure 54: Marked voice quality samples
Clicking on the icon displays the following form allowing the user to either over-ride the ‘Marked’ status or
to add ‘Marked’ status to other samples that have not bee automatically detected as suspect:

Marked samples may then be excluded or included from voice quality analysis and maps and tables using
the norrmal filter event function.
