The conditions for remote (yellow) alarm (FRS0.RRA) detection can
be selected via this bit to allow detection even in the presence of
BER 10**-3:
RRAM = 0
Detection
F4:
F12: FMR0.SRAF = 0: bit2 = 0 in every speech channel per frame.
ESF: FMR0.SRAF = 0: pattern ‘1111 1111 0000 0000…’ in data
F72: bit2 = 0 in every speech channel per frame.
Release
The alarm is reset when above conditions are no longer detected.
RRAM = 1
Detection
F4:
F12: FMR0.SRAF = 0: bit 2 = 0 in 255 consecutive speech
ESF: FMR0.SRAF = 0: pattern ‘1111 1111 0000 0000…’ in data
F72: bit 2 = 0 in 255 consecutive speech channels.
