5 Enter a time- out period sufficient to cover the number of
defined iterations. Generally this is approximately 20
seconds per iteration.
6 Define a different work directory for each channel. Each
work directory will store the recorded speech and MOS
result file for the individual channel.
7 If necessary, change the line impedance settings. Select
the Options button to open the dialog box. Once set “Save
Settings” will allow you to use these settings for other
tests. Check with your local phone- line provider to verify
the line impedance used.

8 Click START TEST.
NOTE
Each iteration will consist of a pair of downlink and uplink data point. The
estimated test time for each iteration is approximately one minute.
It is highly recommended that you use the default 20 secs time-out
between each measurement. This will allow the system to recover from
dropped call.
NOTE
Do not use a directory name with space.
