Receive Remote Alarm Mode
The conditions for remote (yellow) alarm detection can be selected via
this bit to allow detection even in the presence of BER 10
alarm detection is flagged in register FRS.RRA and can be signalled as
an interrupt.

Normal operation
Detection:
Bit 2 = ‘0’ in every speech channel per frame.
Release:
The alarm will be reset when above conditions are no longer
detected.
Detection with BER 10
Detection:
Bit 2 = ‘0’ in 255 consecutive speech channels.
Release:
The alarm will be reset when receiver does not detect the Bit 2 =
’0’ condition for three consecutive pulseframes.
Normal operation
Depending on bit FMR0.SRAF:
Detection with BER 10
Remote alarm detection depending on bit FMR0.SRAF:
Detection:
FS-bit of frame 12 is forced to ‘1’.
Release:
The alarm will be reset when above conditions are no
longer detected.
Detection:
Bit 2 = ‘0’ in every speech channel per frame.
Release:
The alarm will be reset when above conditions are no
longer detected.
Detection:
FS-bit of frame 12 is forced to ‘1’.
Release:
The alarm will be reset when receiver does not detect the
’Fs-bit’ condition for three consecutive multiframes.
