2.7.337 RFI-P
Step 2 Identify and clear any alarms, particularly the “LOS (OCN)” alarm on page 2-164.
Step 3 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
2.7.337 RFI-P
Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)
SONET Logical Objects: STSMON, STSTRM
The RFI Path condition occurs when the ONS 15454 detects an RFI in the an STS-1 signal SONET
overhead because of a fault in another node. Resolving the fault in the adjoining node clears the RFI-P
condition in the reporting node. RFI-P occurs in the terminating node in that path segment.
Clear the RFI-P Condition
Step 1 Verify that the ports are enabled and in service (IS-NR) on the reporting ONS 15454:
a. Confirm that the LED is correctly illuminated on the physical card.
A green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.
b. To determine whether the OC-N port is in service, double-click the card in CTC to open the card
view.
c. Click the Provisioning > Line tabs.
d. Verify that the Admin State column lists the port as IS.
e. If the Admin State column lists the port as OOS,MT or OOS,DSBLD, click the column and choose
IS. Click Apply.
Note If ports managed into IS admin state are not receiving signals, the LOS alarm is either raised
or remains, and the port service state transitions to OOS-AU,FLT.
Step 2 To find the path and node failure, verify the integrity of the SONET STS circuit path at each of the
intermediate SONET nodes.
Step 3 Clear alarms in the node with the failure, especially the “UNEQ-P” alarm on page 2-252 or the
“UNEQ-V” alarm on page 2-254.
Step 4 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
2.7.338 RFI-V
Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)
SONET Logical Objects: VTMON, VT-TERM
