12 FAIL PI-BD reported that Loop Around Test failed.
1. Retry the test.
2. If it continues to fail, try resetting the circuit pack by the
test interface PCS long command. This TEARS down
all other links on this circuit pack (DCS, AUDIX, ISDN,
etc.).
3. If the problem still exists, replace the TN765 circuit pack.
PASS The on-board Loop Around Test on the TN765 circuit pack
passed. Most of the hardware on the circuit pack was tested
except for the TDM Bus buffers. If problem is isolated to
TN765 and this test passes, then replace TN765 circuit pack
since TDM Bus buffers could be at fault.
13 ABORT The TN765 circuit pack has not been reset yet or is currently
being reset.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2. If test continues to abort with error code 13, then check
status of all BX.25 and/or ISDN-PRI links on this TN765
via status link lnk-no. If all links are not in-service, then
reset the TN765 using test interface PCS long.
3. If the TN765 fails to reset, refer to the PI-SCI section of
this manual.
4. Retry the test link lnk-no command.
5. If the test still aborts with error code 13 or from step 2,
and some links are in-service and an error code is still
present, escalate the problem.
