2000 ABORT Response to the request was not received within the
allowable time period.
1. Retry the command at one-minute intervals a
maximum of five times.
2. If the test continues to abort, escalate the problem.
FAIL Failure to detect ground or faulty ground detected on
Ring lead. Display the hardware errors for this trunk, to
determine if the fault was on- or-off board. Look for Error
Type 1025 or 1281 (if both appear in the Hardware Error
Log, pick the most recent error). Error Type 1025
indicates a faulty ground detected on Ring lead (an
off-board fault) and Error Type 1281 indicates failure to
detect (internally generated) ground (an on-board fault).
Faulty ground detected on Ring lead (Error Type 1025):
NOTE:
On TN747B vintage 8 and greater circuit packs,
an incoming seizure during this test may cause it
to fail with an off-board fault.
1. Repeat test. If test passes, ignore the original failure.
If test aborts, follow the recommended procedures.
2. Repeat test with CO line removed.
3. If test fails, replace the circuit pack.
4. If test passes, refer problem to CO.
Failure to detect ground (Error Type 1281):
1. Run the long test sequence. If the CO Demand
Diagnostic Test fails, the Dial Tone Test (#0) fails
with Error Code 2002, AND Error Type 3329 or 3585
appears in the Hardware Error Log (with the same
last occurred time as Error Type 1281 and 1537),
replace the circuit pack.
2. Repeat test with CO line removed.
3. If test fails, replace the circuit pack.
4. If test passes, the CO may be drawing too much
current. Refer problem to CO.
