CTS55 Getting Started With Quicktest
1094.0006.55 5.7 E-6
Explanations:
j
CTS sends a call to the mobile. When the mobile rings, the user must press the relevant phone but-
ton. As a result, a speech link is set up on the first channel, which can be selected in the configura-
tion menu. CTS will terminate the test step with a "
9
"
in the CallTo box if the mobile functions prop-
erly. If the mobile does not accepts the call within a given time period, the test will be terminated with
a "f" in the CallTo box.
k
After link set-up, CTS stores the speech signals received and sends them back to the mobile with a
delay of one second. The user is thus able to speak into the microphone of the mobile with the link
set up and hear the echo after approximately one second in the loudspeaker. This permits the user
to evaluate the received speech quality. If it is okay, the echo test is successfully completed by press-
ing the "OK" key. Otherwise, the test step should be terminated with the corresponding result by
pressing the "FAIL" key.

The test sequence ends with this test step.
