Tone Generator Transmission Test (#40)<br />

Tone Generator Transmission Test (#40)<br />

This <strong>test</strong> verifies that the tone generation hardware on the IPSI or Tone-Clock circuit pack is<br />

capable of generating a subset of system tones <strong>and</strong> a set of <strong>test</strong> tones. This <strong>test</strong> does not verify<br />

all system tones the tone generator produces during normal system operation.<br />

The <strong>test</strong> is performed in two parts. For the first part, the Tone Generator is told to generate the<br />

touch-tone digits. The digits are received <strong>and</strong> checked by a Tone Detector’s touch-tone<br />

detector. If any of the digits fail, the <strong>test</strong> is repeated using a touch-tone detector in another Tone<br />

Detector circuit pack.<br />

For the second part, the Tone Generator is told to generate call-progress tones that are<br />

detected <strong>and</strong> identified by a tone detector. These tones are:<br />

● 440 Hz<br />

● 2225 Hz<br />

● Digital Count<br />

The tone generator is then told to generate a sequence of <strong>test</strong> tones. The output levels are<br />

measured by a tone detector. These tones are:<br />

● 404 Hz at 0 dB<br />

● 1004 Hz at -16 dB<br />

● 1004 Hz at 0 dB<br />

● 2804 Hz at 0 dB<br />

A Tone Detector’s general-purpose tone detector listens for tones <strong>and</strong> measures their quality. If<br />

any of the measured values are not within certain limits, the <strong>test</strong> is repeated using a<br />

general-purpose tone detector in a different Tone Detector circuit pack. If the values are still not<br />

in the acceptable range of the limits, the <strong>test</strong> will fail.<br />

For every failure case of Test #40, do the following:<br />

1. Check that all Tone Detector circuit packs have the same comp<strong>and</strong>ing mode as that<br />

administered for the system. Correct the situation if there is a mismatch.<br />

2. Run the long <strong>test</strong> sequence: <strong>test</strong> tone-clock location long<br />

3. If the problem persists, replace the IPSI or Tone-Clock circuit pack by following the steps<br />

outlined in Replacing the IPSI or Tone-Clock Circuit Pack.<br />

This <strong>test</strong> runs on the following maintenance objects:<br />

● TDM-CLK (TDM Bus Clock)<br />

● TONE-BD (Tone-Clock Circuit Pack)<br />

● TONE-PT (Tone Generator)<br />
