Detector touch-tone detector. If any of the digits fail, the test is repeated using a
touch-tone detector in another Tone Detector circuit pack.
For the second part, the Tone Generator is told to generate call progress tones
that are detected and identified by a tone detector. These tones are:
■ 440 Hz
■ 2225 Hz
■ Digital Count
The tone generator is then told to generate a sequence of test tones whose
output levels are measured by a tone detector. These tones are:
■ 404 Hz at 0 dB
■ 1004 Hz at -16 dB
■ 1004 Hz at 0 dB
■ 2804 Hz at 0 dB
A Tone Detector general purpose tone detector listens for the tones and
measures the quality of the tone. If any of the measured values are not within
limits, the test is repeated using a general purpose tone detector in a different
Tone Detector circuit pack. If the values are still out of the limits, the test will fail.
For all the failure cases of Test #40, do the following:
1. Check that all Tone Detector circuit packs have the same companding
mode as that administered for the system. Correct the situation if there is a
mismatch.
2. Run the long test sequence: test tone-clock PC long repeat 1.
3. If the problem persists, replace the Tone-Clock circuit pack by following
the steps outlined in the ‘‘
How to Replace a Tone-Clock Circuit Pack’’
section.

Result Description/ Recommendation
None ABORT The system was not able to allocate all the resources needed for this test
or there was an Internal System Error.
1 ABORT The system could not allocate all the resources needed to test the DTMF
tones.
