Notes:
a. There are two possible alarm levels for this error typ e: major alarm and
minor alarm. These alarm levels are depend ent 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 numb er of ports capab le of TTR, CPTR
or CCTR detection currently in-service is less than or e qual to 1/2 of the
administered TTR, CPTR or CCTR threshold number.
Otherwise, a minor alarm is raised. In either c ase, run the short test
sequence against the p ort (ETR-PT) and follow the error code procedures
for the individual tests.
The threshold number of ports for servic e is administered using t he
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, d o 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 s ervice for a few seconds. Only 4 of t he 8
would be out of service d ue to the alarm. (There are 4 tone
detectors on each of the two DSPs.) Other than the unlikely
potential of running out of tone d etector 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 p rocess. 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 dup licated, 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 servic e momentarily and tones
are removed from the TDM bus for about 10 sec onds. This means
