Speech Synthesis DTMF Receiver Inquiry
Test (#164)
This test determines the sanity of the port's dual-tone multifrequency (DTMF)
receiver. The on-board microprocessor tests the port's DTMF receiver and
determines if it is in a sane (test passes) or insane (test fails) condition.

Error Test
Code Result Description / Recommendation
ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 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. Wait until the
port is idle (amber LED is off) before retesting.
1. If the port is idle, retry the command at 1-minute intervals up to 5 times.
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 up to 5 times.
Any FAIL The DTMF receiver for this port is insane.
1. If the test fails again, replace the circuit pack.
PASS The DTMF receiver for this port is sane. User-reported troubles should be
investigated using other tests and by verifying other ports on this circuit pack
are working correctly.
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 circuits. A 440-Hz tone is generated for 500 ms 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.
