DUAL T1/E1/J1 FRAMER/LIU COMBO - E1 REGISTER DESCRIPTION
REV. V1.2.0
The following table demonstrates the conditions on the receive side which trigger the Automatic Sa, and A bit
transmission when TSACR1 bits are enabled.
2
NOP_ENB
R/W
0
No power automatic transmission
This bit enables the auto Sa-bit transmission upon detecting Loss of
Power condition. The XRT86VL32 device recognizes the Loss of
Power condition by monitoring the Loss of Power input pin (pin
AB1). When the Loss of Power input pin is HIGH indicates a Loss of
Power condition is occurring. When the Loss of Power input pin is
LOW indicates no Loss of Power condition detected.
Upon detecting Loss of Power condition, E1 framer will transmit the
Alarm bit (A bit) as ‘0’, Sa5 bit as ‘1’, and Sa6 bit as ‘1000’ pattern.
See
Table 42
for the transmit Sa5, Sa6, and A bit pattern upon
detecting Loss of Power condition.
1
NOP_LOSLFA_ENB
R/W
0
No power and LOS/LFA automatic transmission
This bit enables the auto Sa-bit transmission upon detecting the fol-
lowing two conditions:
1.
Upon Loss of Power and Loss of Signal (LOS) or
2.
Upon Loss of Power and Loss of frame alignment (LFA)
When the E1 framer detects any one of the above two conditions,
E1 framer will transmit the Alarm bit (A bit) as ‘1’, Sa5 bit as ‘1’, Sa6
bit as ‘1000’ pattern.
See
Table 42
for the transmit Sa5, Sa6, and A bit format upon
detecting loss of power and LOS/LFA conditions.
0
LOS_2_ENB
R/W
0
LOS 3 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
Sa5 and Sa6 bit as an Auxiliary (10101010...) pattern
See
Table 42
for the transmit Sa5, Sa6, and A bit format upon
detecting LOS condition.
