This attribute indicates the Far-End alarm signal that is currently
received at the DS3 interface. This signal is carried over the Far-
End Alarm and Control (FEAC) bits of DS3 frames. Five far-end
alarm signals can be received: far-end equipment failure that is
received when the far-end terminal has detected a local equipment
failure; far-end Loss Of Signal (LOS) that is received when the far-
end DS3 terminal has declared a LOS failure condition; far-end
Loss of Frame (LOF) when the far-end DS3 terminal has declared a
Loss Of Frame (LOF) failure condition; far-end Alarm Indication
Signal (AIS) when the far-end has declared an AIS failure
condition; far-end Idle when the far-end has declared an Idle signal
condition.
