b. The ETR-PT lost its translation. Testing the ETR-PT is sufficient to reload
its translation. If testing the ETR port does not clear the error, then the
circuit pack containing the defective ETR port should be replaced at a time
when it is convenient to remove a clock board from the system. Follow the
procedures described in
‘‘TONE-BD (Tone-Clock Circuit)’’ on page 8-1659
for replacing a Tone-Clock circuit pack.
c. This error indicates the (ETR-PT) Enhanced Tone Receiver is having
problems detecting touch tones, call-progress tones, or MFC tones. If this
error type is persistently logged, then the circuit pack containing the
defective ETR-PT should be replaced at a time it is convenient to remove a
clock board from the board from the system. Follow the procedures
described in the
‘‘TONE-BD (Tone-Clock Circuit)’’ on page 8-1659
section
for replacing a Tone-Clock circuit pack.
System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the following table. By clearing
error codes associated with the Tone Detection Verification test, for example, you
may also clear errors generated from other tests in the testing sequence.
Tone Detection Verification Test (#42)
This test checks out a single ETR port’s touch-tone receiver mode, MFC
tone-detection/generation mode, and general-purpose tone-detection mode.
During the test sequence, these modes are tested in the following order:
1. Touch-tone receivers
2. General-purpose, call-progress, and maintenance tones
3. MFC tones
