SNI Fiber Out of Frame Query Test (#989)
FAIL The SNI circuit pack has a loss of signal condition, but no fiber out of
frame condition.
Error Code 143: A lightwave transceiver is connected to the SNI circuit
pack.
Error Code 144: No lightwave transceiver is connected to the SNI circuit
pack.
1. Check that the connected circuit pack is physically installed. The
connected circuit pack is the other endpoint of the fiber-link if no
DS1C complex is administered. Check using list fiber-link.
Otherwise, if a DS1C complex is administered, the connected circuit
pack is the DS1C circuit pack connected to the SNI circuit pack.
2. If a lightwave transceiver should not be present, go to step 3. For
example, an SNI connected to a DS1C circuit pack or an SNI with a
metallic connection does not have a lightwave transceiver. Otherwise,
check the lightwave transceiver connections. If OK, 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, that is, both are 9823a or both are 9823b. If they
are not the same type, replace one of the lightwave transceivers:
● 9823a is used for distances up to 4900 feet.
● 9823b is used for distances up to 25,000 feet.
3. Perform the Fiber link fault isolation procedure in Maintenance
Procedures (03-300432).
4. Replace this SNI circuit pack.
5. Replace the connected circuit pack.
