10. Test the alarmed board (test tone UUCSS long). This resets the
board and is required to reload on-board RAM associated with the
TN2182’s DSPs.
11. If all tests pass and the alarm does not resolve, retest with test tone
UUCSS long clear.
12. If the test passes, terminate the repair process. If it fails, replace the
board.
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
TN2182 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 the TONE-BD section for replacing a
tone/clock circuit pack.
c. This error indicates the (ETR-PT) Enhanced Tone Receiver port is having
problems detecting touch tones, call progress or MFC tones. If this error
type is persistently logged, then the TN2182 circuit pack containing the
defective ETR-PT should be replaced at a time it is convenient to remove a
clock board from the system. Follow the procedures described in the
TONE-BD section for replacing a tone/clock circuit pack.
d. 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
TN2182 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 the TONE-BD 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 tables when
inspecting errors in the system. 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.
