DETAILED STEPS
Step 1
Ensure that the fiber connector for the card is completely plugged in. For more information about fiber connections
and card insertion, refer to the Turn Up a Node chapter in the Configuration guide.
Step 2
Ensure that the ports on the far end and near end nodes have the same port rates and FEC settings. For more information
about port rates and FEC settings, refer to the Provision Transponder and Muxponder Cards chapter in the Configuration
guide.
Step 3
If the BER threshold is correct and at the expected level, use an optical test set to measure the power level of the line
to ensure it is within guidelines. For specific procedures to use the test set equipment, consult the manufacturer.
Step 4
If the optical power level is good, verify that optical receive levels are within the acceptable range.
Step 5
If receive levels are good, clean the fibers at both ends according to site practice. If no site practice exists, complete
the procedure in the Maintain the Node chapter in the Configuration guide.
Step 6
If the condition does not clear, verify that single-mode fiber is used.
Step 7
If the fiber is of the correct type, verify that a single-mode laser is used at the far-end node.
Step 8
Clean the fiber connectors at both ends for a signal degrade according to site practice.
Step 9
Verify that a single-mode laser is used at the far end.
Step 10
If the problem does not clear, the transmitter at the other end of the optical line could be failing and require replacement.
Refer to the
Physical Card Reseating, Resetting, and Replacement, on page 451
If the condition does not clear, log into the Technical Support Website at
index.html
for more information or call Cisco TAC (1 800 553-2447).
UNEQ-P
Default Severity: Critical (CR), Service-Affecting (SA)
Logical Object: STSMON, STSTRM
An SLMF UNEQ Path alarm occurs when the path does not have a valid sender. The UNEQ-P indicator is
carried in the C2 signal path byte in the SONET overhead. The source of the problem is the node that is
transmitting the signal into the node reporting the UNEQ-P.
The alarm could result from a PARTIAL circuit or an empty VT tunnel. UNEQ-P occurs in the node that
terminates a path.
If receive levels are good, clean the fibers at both ends according to site practice. If no site practice
exists, complete the procedure in the Maintain the Node chapter in the Configuration guide.
If the condition does not clear, verify that single-mode fiber is used.
If the fiber is of the correct type, verify that a single-mode laser is used at the far-end node.
Clean the fiber connectors at both ends for a signal degrade according to site practice.
Verify that a single-mode laser is used at the far end.
If the problem does not clear, the transmitter at the other end of the optical line could be failing and
require replacement. Refer to the
section.
