Coherent Optics Alarms
These alarms are generated in the multiple scenarios shown:
• RX-LOS
• RX-OTU
• [LOF] Loss-Of-Frame
• [LOM] Loss-Of-Multiframe
• RX-ODU
• [AIS] Alarm-Indication-Signal
• [OCI] Open-Connection-Indication
• RX-OPU
• [PLM] Payload-Mismatch
Alarm message | Meaning |
|---|---|
RX-LOS (Loss of signal) | This Alarm is generated when the NE [Network Equipment] doesn't see light/signal from the far end. |
OTU Alarm (OTU Alarm Indication Signal) | The local interface has received an OTU-AIS signal from the NE at the far end of the fiber, indicating that no OTN OTU signal is being transmitted upstream of (and toward) the local NE |
LOF/LOM (Loss Of Frame/ Multiframe) | LOF is generated when the received frame is error or the signal is degraded [High BER]. LOM alarm occurs when the multiframe alignment process is in the out-of-multiframe (OOM) state for 3 consecutive milliseconds. |
ODU (Optical Data Unit Alarm Indication Signal) | The local interface has received an ODU-AIS signal from the NE at the far end of the fiber, indicating that no OTN OTU or OTN ODU signal is being transmitted upstream of (and toward) the local NE. |
BDI (Backward Defect Indication) | The local interface has received a BDI signal from the NE at the far end of the fiber, indicating that no OTN OTU signal is being transmitted downstream of (and away from) the local NE. |
AIS (Alarm Indication Signal) | The local interface has received an ODU-AIS signal from the NE at the far end of the fiber, indicating that no OTN OTU or OTN ODU signal is being transmitted upstream of (and toward) the local NE. |
OCI (Open-Connection-Indication) | The local interface has received an ODU-OCI signal from the far-end NE, indicating that an optical cross-connect is not present on an upstream node. |
OPU Alarm (Optical Channel Payload Unit) | |
PLM (Payload Mismatch) | PLM is declared when the received PayloadType differs from the expected, pre-provisioned PT value |

Linkdown Policy
This section contains the Linkdown Policy feature Support configuration example.
Overview
This feature is to support to provide an option to the user to apply link down policy for the attributes PRE-FEC BER, RX Power, SNR, Q-Margin and Chromatic Dispersion whenever there is a threshold violation. With current behaviour, whenever these attributes are monitored, user receives the console log, NETCONF notification and SNMP trap if any threshold violation is detected. With this feature, user will have the extra option to enforce the interface shutdown along with the above mentioned notifications. Once the violation is cleared, the interface will be enabled again automatically.
