DF_S
2
0
Line driver status indication
= 0: Normal operation
= 1: Line driver short circuit is detected.
Note:
If DF_IM=0
A ‘0’ to ‘1’ transition on this bit causes an interrupt if DF _IES bit is ‘0’.
Any changes of this bit causes an interrupt if DF_IES bit is set to ‘1’.
AIS_S
1
0
Alarm Indication Signal status detection
= 0: No AIS signal is detected in the receive path
= 1: AIS signal is detected in the receive path
Note:
If AIS_IM=0
A ‘0’ to ‘1’ transition on this bit causes an interrupt if AIS _IES bit is ‘0’.
Any changes of this bit causes an interrupt if AIS_IES bit is set to ‘1’.
LOS_S
0
Loss Of Signal status detection
= 0: Loss of signal on RTIPn/RRINGn is not detected
= 1: Loss of signal on RTIPn/RRINGn is detected.
Note:
If LOS_IM=0
A ‘0’ to ‘1’ transition on this bit causes an interrupt if LOS _IES bit is ‘0’.
Any changes of this bit causes an interrupt if LOS_IES bit is set to ‘1’.
