Result
Error Codes 40 and 41: Remote Maintenance Looparound Test
failed because data was corrupted.
Error Codes 2000-2004: Remote Maintenance Looparound Test
failed because data was lost.
Test cannot indicate which DATA-CHL is defective.
1. Check dial plan to ensure data channel extensions are set up
as local extensions rather than remote or UDP extensions.
2. Determine if links exist on DATA-CHLs (status link).
3. Execute tests #110 and #111 in the Short Test Sequence for
the target DATA-CHL to determine which actions to take,
based on the results below.
a. Both Test results are PASS: Arbitrarily chosen DATA-CHL
is probably defective.
b. Only one test result is FAIL for any other DATA-CHLs not
in use: TDM Bus is probably defective.
c. Test #110 result is FAIL and Test #111 result is PASS (for
target DATA-CHL): Either the RDM Bus or Tone-Clock
circuit pack is defective.
Description/Recommendation
1. Run Short Test Sequence for each
DATA-CHL not in use.
2. Note the test results for Tests #110 and #111
for each DATA-CHL.
3. Remove DATA-CHLs (remove data-module
ext) for which the results of Tests #110 and
#111 were both FAIL.
4. Replace the Netcon or NetPkt circuit pack at
earliest convenience.
1. Check for TDM bus alarms or errors
(TDM-BUS) and/or Tone-Clock circuit pack
alarms or errors (TONE-BD, TONE-PT, and
TDM-CLK).
2. If there are no errors or alarms, the target
DATA-CHL, or Netcon or NetPkt circuit pack
are probably defective: refer to steps in 3a
above.
3. If there are errors or alarms, refer to
Maintenance documentation to clear the
alarms and errors.
4. Repeat the test.
