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’.
Loss Of Signal status detection
= 0: Loss of signal on RTIP/RRING is not detected.
= 1: Loss of signal on RTIP/RRING 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’.
Reserved.
Indicating the status of Remote Loopback
= 0: The remote loopback is inactive.
= 1: The remote loopback is active (closed).
