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.

NO
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 the reset board UUCSS
command.
3. Run the test again. If it fails, the ID chip on board may be bad. Replace
the board and retest.
