Data Sheet
Loss of Frame Alignment
The framer has lost synchronization and bit FRS0.LFA is set.
It is set during alarm simulation.
Set when the framer has reached multiframe alignment in F12 or F72
format. With the negative transition of bit FRS0.LMFA this bit is set. It
is set during alarm simulation.
Loss of Multiframe Alignment
Set when the framer has lost the multiframe alignment in F12 or F72
format. With the positive transition of bit FRS0.LMFA this bit is set. It
is set during alarm simulation.
Alarm Indication Signal (Blue Alarm)
This bit is set when an alarm indication signal is detected and bit
FRS0.AIS is set. If IPC.SCI is set high this interrupt status bit is
activated with every change of state of FRS0.AIS.
It is set during alarm simulation.
This bit is set when a loss of signal alarm is detected in the received
data stream and FRS0.LOS is set. If IPC.SCI is set high this interrupt
status bit is activated with every change of state of FRS0.LOS.
It is set during alarm simulation.
Set if a remote alarm (yellow alarm) is cleared and bit FRS0.RRA is
reset. It is set also after alarm simulation is finished and no remote
alarm is detected.
Remote Alarm
A remote alarm (yellow alarm) is detected. Set with the rising edge of
bit FRS0.RRA. It is set during alarm simulation.
