Error Test
Code Result Description / Recommendation
1 FAIL Loop back on TDM Bus A failed. Loop back on TDM Bus B passed.
2 FAIL Loop back on TDM Bus B failed. Loop back on TDM Bus A passed.
3 FAIL Loop back on both TDM Buses failed.
12 FAIL Loop back on TDM Bus B failed. Loop back on TDM Bus A aborted because
the system could not allocate time slots.
21 FAIL Loop back on TDM Bus A failed. Loop back on TDM Bus B aborted because
the system could not allocate time slots.
None FAIL The test tone was not detected correctly after being looped through the EI
circuit pack.
1. If Error Type 2305 has been logged against the EI circuit pack in the last 5
2. Run the tests for the active Tone-Clock on the PN that contains the indicted
3. If the tone-clock is healthy, repeat the short test on the EI board.
4. If this test continues to fail, replace the EI circuit pack.
PASS Test tone was correctly detected after internal EI loop back on both TDM
buses.
1. Refer to other EI circuit pack tests if the links between this EI circuit pack
0 NO No board was detected by the test.
BOARD
1. Check the error log for wrong board (error 125) or no board (error 131).
2. Check that the board is properly translated and inserted. If so, check for
3. Run the test again. If it fails, the ID chip on board may be bad. Replace
