Detection with BER 10
Remote alarm detection depending on bit FMR0.SRAF:
AIS (blue alarm) is indicated, when two or less zeros in the
received bit stream are detected in a time interval of 12 frames.
AIS (blue alarm) detection is only enabled, when framer is in
asynchronous state. The alarm is indicated, when three or less
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.
Detection
Pattern ‘1111 1111 0000 0000…’ in data link channel.
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
Pattern ‘1111 1111 0000 0000…’ in data link channel.
Release:
The alarm will be reset when receiver does not detect ‘DL
pattern’ for three times in a row.
Detection:
Bit 2 = ‘0’ in 255 consecutive speech channels.
Release:
The alarm will be reset when receiver does not detect the
