Result
Description / Recommendation
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 for Avaya Aura Communication Manager, Media
Gateways and Servers (03-300432).
4. Replace this SNI circuit pack.
5. Replace the connected circuit pack.
