4. If the test passes, terminate the repair process. If the test fails,
replace the board.
5. Check to see if the board is duplicated (list cabinet and status
port-network on the affected port network.)
6. If the board is not duplicated, use test tone UUCSS long to resolve
the error. The long test resets the board and is required to reload
on-board RAM associated with the TN2182”s DSPs. The effect is
that tone detectors are taken out of service momentarily and tones
are removed from the TDM bus for about 10 seconds. This means
no dial or touch tones during this interval, which probably will not
affect calls in progress, but could cause a call origination to abort or
cause a user to not get dial tone when going off hook.
7. If all tests pass and the alarm does not resolve, retest (test tone
UUCSS long clear).
8. If the test passes, terminate the repair process. If it fails, replace the
circuit pack at the customer’s convenience.
9. If the board is duplicated, switch to the standby side (set tone).
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.
