Remarks
Optional
The system generates an error
frame alarm when the number
of error frames in a specific
time period (that is, the window
size) exceeds the
corresponding predefined
threshold.
By default, this function is
enabled.
Optional
When the alarm threshold is set
to 0, a lot of alarms are
generated immediately. Since
alarm events are carried in the
OAM packets, a lot of OAM
packets are generated. In this
case, OAM packets may be
lost.
By default, the window size is
10 second, and the alarm
threshold is 20 frames.
Optional
The system generates an error
frame seconds summary alarm
when the number of error frame
seconds (in an error frame
second, at least one error
frame occurs) in a specific time
period (for example, 1 minute)
exceeds the corresponding
predefined threshold.
By default, this function is
enabled.
Optional
By default, the window size is
600 (in unit of 100 ms), and the
alarm threshold is 1 second.
Optional
When both the total number of
error bits and the bit error rate
of the data transferred between
the OLT and ONUs exceed the
alarm threshold, a port bit error
rate alarm occurs.
By default, this function is
enabled.
