SNI Destructive Facility Test (#757)
This test is destructive.

The SNI runs a destructive looparound of the off-b oard and on-board

looparounds. This test returns the result of the on-board looparound, while test

756 returns the result of the off-board loop around.

1416 ABORT The lightwave transceiver is not present for endpoint 2 of the fiber link (list
fiber-link can be used to display fiber link endp oints).
1. If a lightwave transceiver is not supposed to be present, d o nothing. For
example, an SNI connected to a DS1 CONV circuit pack or an SNI with a
metallic connec tion does not have a lightwave tr ansceiver. This test can
only be run when a lightwave transceiver exists.
2. Check the lightwave transceiver connections.
3. Replace the lightwave transceiver. If a fiber out of frame condition exists
and lightwave transceivers are used, check that the lightwave transceivers
are of the same type (both are 9823a or both are 9823b). If they are not the
same type, replace one of the lightwave transceivers.
4. Replace the SNI circuit pack.
127 FAIL The data is not correctly looped around on endpoint 1 of the fiber link (list
fiber-link can be used to display fiber link endp oints).
1. Check the lightwave transceiver.
2. Replace the lightwave transceiver. If a fiber out of frame condition exists
and lightwave transceivers are used, check that the lightwave transceivers
are of the same type (both are 9823a or both are 9823b). If they are not the
same type, replace one of the lightwave transceivers.
3. Replace the SNI circuit pack.
227 FAIL The data is not correctly looped around on endpoint 2 of the fiber link (list
fiber-link can be used to display fiber link endp oints).
1. Check the lightwave transceiver.
2. Replace the lightwave transceiver. If a fiber out of frame condition exists
and lightwave transceivers are used, check that the lightwave transceivers
are of the same type (both are 9823a or both are 9823b). If they are not the
same type, replace one of the lightwave transceivers.
3. Replace the SNI circuit pack.
PASS No problems associated with this test are detected on the SNI (s).
