Receive Remote Alarm Mode
The conditions for remote (yellow) alarm (FRS0.RRA) detection can
be selected by this bit to allow detection even in the presence of a bit
error rate of up to 10
RRAM = 0
Detection
F4: Bit2 = 0 in every speech channel per frame.
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 (bit error rate 10
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.
RRAM
H
– FMR0.SRAF = 1: S-bit of frame 12 is forced to “1”
– FMR0.SRAF = 1: bit2 = 0 in every speech channel
Bit2 = 0 in 255 consecutive speech channels.
– FMR0.SRAF = 1: S-bit of frame 12 is forced to “1”
– FMR0.SRAF = 1: bit 2 = 0 in 255 consecutive speech
T1: Alarm handling is done according ITU-T G. 704+706
J1: Alarm handling is done according ITU-T JG. 704+706
