EXP-INTF (Expansion Interface Circuit Pack)
Issue 1 June 2005 1205
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 minutes, this test could have failed due to the associated slips. If
so, first resolve the 2305 error, and then repeat the test.
2. Run the tests for the active Tone-Clock on the PN that contains the
indicted EI circuit pack to verify that dial-tone is supplied.
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 and the EI or SNI circuit pack on the other end of the fiber is not
functioning correctly.

BOARD
No board was detected by the test.
1. Check the error log for wrong board (error 125) or no board (error
131). Resolve either of these issues, if applicable.
2. Check that the board is properly translated and inserted. If so, check
for hyperactivity (error 1538). If hyperactive, use reset board
location.
3. Run the test again. If it fails, the ID chip on board may be bad.
Replace the board and retest.
