ETR-PT (Enhanced Tone Receiver Port)

FAIL Hardware audit failed.
1. Use list configuration carrier to get the board type and location. If the
board is TN744, then do Steps 2-4; if it is TN2182, do Steps 5-12.
2. Execute 3 commands: busyout board UUCSS, reset board UUCSS,
and release board UUCSS. Reset is required to reload RAM
associated with the TN744’s DSPs. This will take all 8 tone detector
ports out of service for a few seconds. Only 4 of the 8 would be out of
service due to the alarm. (There are 4 tone detectors on each of the
two DSPs.) Other than the unlikely potential of running out of tone
detector resources in the switch, there is no other effect when the
board is reset.
3. Test the board (test board UUCSS long).
4. If the test passes, terminate the repair process. If the test fails, replace
the board. Follow the procedures in TONE-BD.
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. Follow the procedures in
TONE-BD.
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. Follow the procedures in TONE-BD.
PASS The ETR Port has passed the sanity inquiry.
