Expansion Interface Lightwave Transceiver Loop-Around Test (#242)
This test is destructive.
This test requires that the EI circuit pack first be busied out. If the system has a duplicated Port
Network Connectivity, this test cannot be run on an EI circuit pack that resides on the current
active PNC due to restrictions that prohibit the busying-out of certain components that are part
of the active PNC. If this test is run on an EI circuit pack that is part of the standby PNC, this test
is not destructive and no service outages will take place.
In a system without duplicated Port Network Connectivity, where this EI circuit supports an IPSI
to PN link, this test will disrupt service to one or more PN’s. If the EI circuit pack is part of a
PN-to-PN link in a Direct Connect system, service between the two PNs will be disrupted.
3 or 4 FAIL The failure codes only apply to a system equipped with a Center
Stage Switch. They indicate that the test aborted or failed for the first
connection from the EI board under test to another PN, and that the
test tone was detected correctly in one direction, but not the opposite
direction when the connection was between the EI board under test
and a different PN than was used in the first connection.
1. Run the test for the active Tone-Clocks on the PNs for which the
defective EI board provides a link. This determines if the dial tone
is being supplied.
2. Perform the Fiber link fault isolation
in Chapter 4: General
troubleshooting in Maintenance Procedures (03-300192).
PASS The tone was successfully transmitted in both directions. Both EI
boards, SNI boards, DS1 converter circuit packs, and their lightwave
transceivers are functioning properly.

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.
