Notes:
a. There are two possible alarm levels for this error type: major alarm and
minor alarm. These alarm levels are dependent on the administered
thresholds for TTR, CPTR and CCTR. Each ETR port is capable of
operating an any of these.
A major alarm is raised if the total number of ports capable of TTR, CPTR
or CCTR detection currently in-service is less than or equal to 1/2 of the
administered TTR, CPTR or CCTR threshold number.
Otherwise, a minor alarm is raised. In either case, run the short test
sequence against the port (ETR-PT) and follow the error code procedures
for the individual tests.
The threshold number of ports for service is administered using the
change system-parameters maintenance command.
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.
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).
