Speech Synthesis DTMF Receiver Inquiry Test
(#164)
This test determines the sanity of the port’s 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.
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 one-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 the command at one-minute
intervals a maximum of 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 one-minute intervals a maximum of
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 verifying
other ports on this circuit pack are working correctly.
