Speech Synthesis DSP Tone Test (#165)
The digital signal processor (DSP) associated with each port can generate a
440-Hz tone whose presence can be detected by TN748 General Purpose Tone
Detector circuit packs. A 440-Hz tone is generated for 500 msec on a specified
time slot which is being listened to by the detector circuit. If the detector
determines the tone is present on the time slot, the test passes; otherwise, it fails.

Result Description/ Recommendation
ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1000 ABORT System resources required to run this test are not available. The port may be
busy with a valid call and therefore unavailable for certain tests. You must wait
until the port is idle (yellow LED if off) before retesting.
1. If the port is idle retry command at 1-minute intervals a maximum of 5
times.

1003 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1021 ABORT The 440-Hz tone was not detected by the Tone Detector circuit and inter-digit
time-out has occurred on the Tone Detector circuit.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to abort, verify all Tone Detector circuit packs in the
system are functioning correctly by checking the Error Log and using the
test board PCSS long command. Replace any faulty Tone Detector circuit
packs and repeat the test.
3. If the test continues to abort, replace the Speech Synthesis circuit pack.
2000 ABORT Response to the test request was not received within the allowable time period.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
Any FAIL The 440-Hz tone was not detected by the Tone Detector circuits.
1. If the test fails again, verify all Tone Detector circuit packs in the system are
functioning correctly by checking the Error Log and using the test board
PCSS long command. Replace any faulty Tone Detector circuit packs and
repeat the test.
2. If the test fails again, replace the Speech Synthesis circuit pack.
PASS The 440-Hz tone has been detected correctly. User-reported troubles should be
investigated using other tests and verifying other ports on this circuit pack are
working correctly.
