Remarks
Optional
By default, this function is
enabled.
Optional
When the total number of error
frames or the error frame rate
of the data transferred between
the OLT and ONUs exceeds
the alarm threshold, a frame
error rate alarm occurs.
By default, this function is
enabled.
Optional
By default, the monitor direction
is up-down-link, and the
threshold of frame error rate
alarms is 1 (the unit is 10
Optional
The system generates an LLID
mismatch frame alarm when
the time slots are used in
disorder, that is, an ONU uses
another ONU's time slot to
forward data.
By default, this function is
disabled.
Optional
By default, the threshold of
LLID mismatch alarms is 5000
frames.
Optional
The system generates a local
stable alarm when an ONU
misuse occurs in the system,
for example, when an OAM 2.0
ONU and an OAM 3.3 ONU are
mixed in the same system. (All
ONUs in the same system must
adopt the same OAM version).
This alarm is generated at the
OLT side.
By default, this function is
enabled.
Optional
The system generates a critical
event alarm when one of the
following critical events occurs:
local link fault and dying gasp.
-9
