FAIL

Failure to detect ground or faulty ground detected on Ring lead.  Display the 

hardware errors for this trunk, to determine whether 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 or media module.

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 or 
media module.

2. Repeat test with CO line removed.

3. If test fails, replace the circuit pack or media module.

4. If test passes, the CO may be drawing too much current.  Refer 

problem to CO.

PASS

This test verifies that the port is able to apply ground for outgoing calls and 

detect ground for incoming calls; however, it does not provide information 

about whether a CO line is actually connected.  User-reported troubles on 

this port should be investigated by using other port tests and by examining 

trunk or external wiring.
