Line driver status indication
= 0: normal operation
= 1: line driver short circuit is detected.
Note:
If DF_IM=0 and DF_IES=0, a ‘0’ to ‘1’ transition on this bit will cause an interrupt.
If DF_IM=0 and DF_IES=1, any changes on this bit will cause an interrupt.
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 and AIS_IES=0, a ‘0’ to ‘1’ transition on this bit will cause an interrupt.
If AIS_IM=0 and AIS_IES=1, any changes on this bit will cause an interrupt.
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 and LOS_IES=0, a ‘0’ to ‘1’ transition on this bit will cause an interrupt.
IF LOS_IM=0 and LOS_IES=1, any changes on this bit will cause an interrupt.
