Expansion Interface Local Looparound (#240)
This test is nondestructive. The EI local loop around is similar to the Lightwave Transceiver
Looparound test (#242). A test tone is received by the EI being tested, but is not transmitted out
to the fiber interface before being looped back. The loop back is internal to the circuit pack.
Thus, this test does not interfere with the normal fiber data stream.

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.

Description / Recommendation
1 ABRT Could not allocate time slot on TDM Bus A. Loop back passed on TDM
Bus B.
1. If there is no reason to doubt that the EI circuit pack can transfer data
to or from a TDM Bus, then since the test passed on one bus, assume
that the test passes on the other bus.
2. If this test continues to abort with the same error, rerun test at
1-minute intervals up to 3 times.
3. If the test still does not pass on the other TDM Bus, follow the
procedure for ABORT Error Code 3.
