OLT port view, FTTH view 

2: System level 

uplink: Specifies the monitor direction. Only uplink data will be monitored. 

downlink: Specifies the monitor direction. Only downlink data will be monitored. 

up-down-link: Specifies the monitor direction. Both uplink and downlink data between OLT and ONU 

will be monitored. 

threshold  threshold: Specifies the alarm threshold of bit error rate. The threshold  argument ranges 

from 1 to 10

9

 and defaults to 10 (in 10

-9

). 

 

Use the alarm bit-error-rate command to configure the monitor direction and the alarm threshold of the 

bit error rate.  

Use the undo alarm bit-error-rate command to restore the default monitor direction and alarm 

threshold.
