13.1.9 OLT Link Down Detection
If the power of ONU is turned off by user, this ONU is supposed to send the alarm mes-
sage of dying-gasp to OLT. When the last ONU is deregistered from the V8102 after it
generates an alarm by ONU dying-gasp event, we can regard that the link of this GPON
port is down and it
’s not the cable connection problem.
To enable/disable GPON link down detection, use the following command.
Command Mode Description
olt cable-down enable
Global
Enables GPON link down detection
olt cable-down disable Disables GPON link down detection
To set a number of ONUs that are deregistered without dying-gasp alarm message for de-
tecting the PON link of OLT, use the following command.
Command Mode Description
olt cable-down reference-count
<1-8>
Global
Sets the number of deregistered ONUs without sending
dying-gasp alarms. The numbers indicate the abnormal
behavior that the link of GPON port is down.
1-8: count of inactive ONU (default: 3)
no olt cable-down reference-
count
Deletes a configured number of deregistered ONUs
and returns to the default value.
To use this feature, the dying-gasp alarms should be enabled for each GPON-OLT node.
To display the state of GPON link down detection, use the following command.
Command Mode Description
show olt cable-down Enable/Global

detection.
