Description
LINK/ACT
ON means the carrier signal has been received.
OFF means no carrier signal has been received.
Blinking means data is being transmitted or/and received.
LP/AL
ON means the interface is in a loopback.
Blinking means an AIS, LFA, or RAI alarm signal is present.
OFF means no loopback or alarm is present.
Note:
AIS = Alarm indication signal; LFA = loss of frame alignment; RAI = Remote alarm
indication
