Rdi-P; Rfi-L; Rfi-P - Cisco ONS 15327 User Documentation

Alarm Procedures
Procedure: Clear the RCVR-MISS Alarm on the XTC-14 Port
Ensure that the device attached to the XTC-14 port is operational.
Step 1
Verify that the cabling is securely connected.
Step 2
Verify that the pinouts are correct.
Step 3
Replace the receive cable if Steps 1 – 3 do not clear the alarm.
Step 4

14.4.99 RDI-P

See the

14.4.100 RFI-L

•
A remote-fault indication (RFI) alarm occurs when the ONS 15327 detects a remote-fault indication
(RFI) in the SONET overhead because of a fault in another node. Resolving the fault in the adjoining
node clears the RFI-L alarm in the reporting node.
RFI-L indicates that the alarm is occurring at the line level. The line layer is the segment between two
SONET devices in the circuit and is also known as a maintenance span. The line layer deals with SONET
payload transport. The line layer functions include multiplexing and synchronization.
Procedure: Clear the RFI-L Condition on the OC-N Card
Step 1 Login to the far-end node from the reporting ONS 15327.
Check for alarms in the far-end node, especially LOS.
Step 2
Resolve alarms in the far-end node.
Step 3

14.4.101 RFI-P

•
A remote failure indication path (RFI-P) alarm occurs when the ONS 15327 detects an RFI in the
SONET overhead because of a fault in another node. Resolving the fault in the adjoining node clears the
RFI-P alarm in the reporting node.
RFI-P occurs in the node that terminates a path. The path layer is the segment between the originating
equipment and the terminating equipment. This segment may encompass several consecutive line
segments. The originating equipment puts bits together into a SONET payload and the terminating
equipment breaks the bits apart again. SONET multiplexers, such as the ONS 15327, often perform the
origination and termination tasks of the SONET payload.
An RFI-P error message on the ONS 15327 indicates that the node reporting the RFI-P is the terminating
node on that path segment.
