Expansion Interface 2-way Transmission Test (#241)

This test is nondestructive. The EI 2-way transmission test is a basic connectivity

test between two PNs. The test first sends dialtone from the c abinet of the EI

circuit pack und er test through the Center Stage Switch, through the DS1 CONV

1 FAIL Loopback on TDM Bus A failed. Loopback on TDM Bus B passed.
2 FAIL Loopback on TDM Bus B failed. Loopback on TDM Bus A passed.
3 FAIL Loopback on both TDM Buses failed.
12 FAIL Loopback on TDM Bus B failed. Loopback on TDM Bus A aborted bec ause
the system could not allo cate time slots.
21 FAIL Loopback on TDM Bus A failed. Loopback on TDM Bus B aborted bec ause
the system could not allo cate 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 d ial-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 loopback on both TDM
Busses.
1. Refer to other EI circuit pack tests if the links between this EI circuit pack
and the EI or Switch Node Interface circuit pack on the other end of the
fiber is not functioning correctly.
0NO
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 th e 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.
