Notes on OMCI Alarms Supported by VOLTHA

Below Table describes the list of OMCI Alarm notifications supported by VOLTHA:

| ME Class ID | Alarm BitMap No | Alarm Name | Description | | ———— | ————— | ———- | ———– | | CircuitPackClassID | 0 | Equipment Alarm | A failure on an internal interface or failed self-test | | CircuitPackClassID | 2 | ONU self-test failure | Failure of circuit pack autonomous self-test | | CircuitPackClassID | 3 | Laser end of life | Failure of transmit laser imminent | | CircuitPackClassID | 4 |Temperature yellow | No service shutdown at present, but the circuit pack is operating beyond its recommended range | | CircuitPackClassID | 5 |Temperature red | Service has been shut down to avoid equipment damage. The operational state of the affected PPTPs indicates the affected services | | PhysicalPathTerminationPointEthernetUniClassID | 0 | LAN-LOS | No carrier at the Ethernet UNI | | OnuGClassID | 0 | Equipment Alarm | Functional failure on an internal interface | | OnuGClassID | 6 | ONU self-test failure | ONU has failed autonomous self-test | | OnuGClassID | 7 | Dying gasp | ONU is powering off imminently due to loss of power to the ONU itself | | OnuGClassID | 8 | Temperature yellow | No service shutdown at present, but the circuit pack is operating beyond its recommended range | | OnuGClassID | 9 | Temperature red | Some services have been shut down to avoid equipment damage. The operational state of the affected PPTPs indicates the affected services | | OnuGClassID | 10 | Voltage yellow | No service shutdown at present, but the line power voltage is below its recommended minimum. Service restrictions may be in effect, such as permitting no more than N lines off-hook or ringing at one time | | OnuGClassID | 11 | Voltage red | Some services have been shut down to avoid power collapse. The operational state of the affected PPTPs indicates the affected services | | AniGClassID | 0 | Low received optical power | Received downstream optical power below threshold | | AniGClassID | 1 | High received optical power | Received downstream optical power above threshold | | AniGClassID | 4 | Low transmit optical power | Transmit optical power below lower threshold | | AniGClassID | 5 | High transmit optical power | Transmit optical power above upper threshold | | AniGClassID | 6 | Laser bias current | Laser bias current above threshold determined by vendor; laser end of life pending |
