LOS indicates a Loss of Signal alarm. This means
that the ADSL received pilot tone power was 6dB
or more below its reference power. Pilot tones do
not carry data and are used for line synchronization.
LOF indicates a Loss of Frame alarm. Loss of
Frame occurs when the expected ADSL framing
bit sequence is not detected indicating a loss of
synchronization.
LCD FAST indicates an ATM Loss of Cell
Delineation in the Fast mode. Cell boundaries must
be maintained for proper ATM synchronization, and
this alarm indicates that the cell beginning and end
location have been lost.
LCD INTR indicates an ATM Loss of Cell
Delineation in the Interleaved mode.
LOM indicates a Loss of Margin. This means that
the measured signal-to-noise-ratio (SNR) was
below the required SNR as set by the DSLAM.
