LOSLFA_1_ENB
R/W
0
LOS/LFA 1 automatic transmission
This bit enables the automatic Sa-bit transmission upon detecting
Loss of Signal (LOS) or Loss of frame alignment (LFA) condition.
Upon detecting Loss of Signal or Loss of Frame alignment condi-
tion, E1 framer will transmit the Sa5 bit as ‘1’, and Sa6 bit as ‘0’ pat-
tern.
See
Table 42
for the transmit Sa5, Sa6, and A bit pattern upon
detecting LOS or LFA conditions.
6
LOS_1_ENB
R/W
0
LOS 1 automatic transmission
This bit enables the auto Sa-bit transmission upon detecting Loss of
Signal (LOS) condition.
Upon detecting Loss of Signal condition, E1 framer will transmit the
Alarm bit (A bit) as ‘1’, Sa5 bit as ‘1’, and Sa6 bit as ‘1110’ pattern.
See
Table 42
for the transmit Sa5, Sa6, and A bit pattern upon
detecting LOS condition.

LOSLFA_2_ENB
R/W
0
LOS/LFA 2 automatic transmission
This bit enables the auto Sa-bit transmission upon detecting Loss of
Signal (LOS) or Loss of frame alignment (LFA) condition.
Upon detecting Loss of Signal or Loss of Frame alignment condi-
tion, E1 framer will transmit the Alarm bit (A bit) as ‘1’, Sa5 bit as ‘0’,
and Sa6 bit as ‘0’ pattern.
See
Table 42
for the transmit Sa5, Sa6, and A bit pattern upon
detecting LOS or LFA conditions.

0
LOS/LFA 3 automatic transmission
This bit enables the auto Sa-bit transmission upon detecting Loss of
Signal (LOS) or Loss of frame alignment (LFA) condition.
Upon detecting Loss of Signal or Loss of Frame alignment condi-
tion, E1 framer will transmit the Alarm bit (A bit) as ‘0’, Sa5 bit as ‘1’,
and Sa6 bit as ‘1100’ pattern.
See
Table 42
for the transmit Sa5, Sa6, and A bit pattern upon
detecting LOS/LFA conditions.

0
LOS/LFA 4 automatic transmission
This bit enables the auto Sa-bit transmission upon detecting Loss of
Signal (LOS) or Loss of frame alignment (LFA) condition.
Upon detecting Loss of Signal or Loss of Frame alignment condi-
tion, E1 framer will transmit the Alarm bit (A bit) as ‘0’, Sa5 bit as ‘1’,
and Sa6 bit as ‘1110’ pattern.
See
Table 42
for the transmit Sa5, Sa6, and A bit pattern upon
detecting LOS/LFA conditions.
