SNI Fiber Out of Frame Query (#989)
This test is nondestructive.
The SNI circuit pack reports whether a fiber out of frame condition exists, whether
a loss of signal condition exists, and whether the lightwave transceiver is present.

Result Description / Recommendation
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 3 times.
1415 ABORT The lightwave transceiver is absent.
1. If a lightwave transceiver should not be present, do nothing. For example,
an SNI connected to a DS1C circuit pack or an SNI with a metallic
connection does not have a lightwave transceiver.
2. Otherwise, check the lightwave transceiver connections.
3. 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.
4. If the test continues to abort, replace the SNI circuit pack.
2300 ABORT The downlink message necessary to run this test could not be sent.
1. Retry the command at 1-minute intervals up to 3 times.
2301 ABORT The software timer could not be set before sending the downlink message
necessary to run this test.
1. Retry the command at 1-minute intervals up to 3 times.
2304 ABORT SNI circuit pack responded that it is not able to run the test requested by
software.
1. Retry the command at 1-minute intervals up to 3 times.
