Alarm Indication Signal: Detection and recovery is flagged by bit FRS0.AIS and
ISR2.AIS. Transmission is enabled via bit FMR1.XAIS.
Loss of Signal: Detection and recovery is flagged by bit FRS0.LOS and ISR2.LOS.
Remote Alarm Indication: Detection and release is flagged by bit FRS0.RRA, RSW.RRA
and ISR2.RA/RAR. Transmission is enabled via bit XSW.XRA.
AIS in Time-Slot 16: Detection and release is flagged by bit FRS1.TS16AIS and
ISR3.AIS16. Transmission is enabled by writing all ones in registers XS1-16.
LOS in Time-Slot 16: Detection and release is flagged by bit FRS1.TS16LOS.
Transmission is enabled by writing all zeros in registers XS1-16.
Remote Alarm in Time-Slot 16: Detection and release is flagged by bit FRS1.TS16RA
and ISR3.RA16. Transmission is enabled via bit CCR1.XTS16RA or XS1.2 .
Transmit Line Shorted: Detection and release is flagged by bit FRS1.XLS and
ISR1.XLSC.
Transmit Ones Density: Detection and release is flagged by bit FRS1.XLO and
ISR1.XLSC.
