Tone Generator Transmission Test (#40)

The purpose of this test is to verify that the tone generation hardware on the IPSI

or Tone-Clock circuit pack is capable of generating a subset of system tones and

a set of test tones. This test does not verify all system tones the tone generator

produces during normal system operation.

The test is performed in two parts. For the first part, the Tone Generator is told to

generate the touch-tone digits. The digits are received and checked by a Tone

Detector's 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:

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's general-purpose tone detector listens for tones and measures

their quality. 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 every failure case 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

2. Run the long test sequence: test tone-clock PC long repeat 1.

3. If the problem persists, replace the IPSI or Tone-Clock circuit pack by

following the steps outlined in
