Event Codes
The following table provides a description of the code displayed in the Event Code field. The displayed code represented the last event that occurred on the selected ONT.
| Event Code | Description | Notes |
| ACTIVATED | Occurs when the selected ONT becomes operational. | |
| DEACTIVATED | Occurs when communication with the selected ONT is lost. | |
| UNKNOWNPASSWORD | Occurs when activation of the selected ONT fails, due to an unknown ONT password. | Abnormal ranging/activation failure. |
| KEYSYNCFAIL | Occurs when the PON encryption key change sequence fails. | Should continue operation with the current key, until the next key change cycle. |
| OOR | Out of Range - Occurs when the selected ONT is detected to be beyond the range of the PON. | ONT is automatically placed in e-stop mode. |
| UNEXPECTED |
Occurs when an unexpected serial number is detected. | |
| MEM |
Message Error Message - Occurs when an unknown PLOAM message is received from the selected ONT. | Isolated occurrences probably due to transmission errors. Otherwise, abnormal ONT behavior. |
| PROV | Occurs when the selected ONT is provisioned. | |
| SIGDEGRADE |
Signal Degrade - Occurs when the Bit Error Rate (BER) exceeds the provisioned signal degrade threshold. | Indicates poor optical signal quality. |
| WINDOWSDRIFT |
Occurs when the range to the selected ONT drifts out of a small window centered on the original range value. | Should cause an automatic re-range of the ONT. |
| REMERRIND |
Remote Error Indicator - Occurs when the selected ONT reports a non-zero value for the bit interleaved parity (BIP) error count. | Indicates poor optical signal quality. |
| DEACTIVATEFAIL |
Occurs if the selected ONT fails to respond to the deactivation command | Abnormal ONT behavior. |
| MACTXVRFAIL |
MAC Transceiver Failure | Transceiver overheating or other hardware failure. |
| SUSFIBERBREAK |
Suspected Fiber Break - Occurs when communication is lost with all ONTs on the PON. | |
| RANGETIMEOUT |
Occurs when an attempt to activate the selected ONT fails due to a timeout. | Abnormal ranging/activation failure |
