Transparent Mode
Setting this bit enables the transparent mode:
In transmit direction bit 8 of every FS/DL time slot from the system
internal highway (XDI) is inserted in the F-bit position of the outgoing
frame. Internal framing generation, insertion of CRC and DL data is
disabled.
Transmit Remote Alarm (Yellow Alarm)
If high, remote alarm is sent on the PCM route. Clearing the bit
removes the remote alarm pattern. Remote alarm indication depends
on the multiframe structure as follows:
F4:
F12: – FMR0.SRAF = 0: bit2 = 0 in every speech channel
ESF: – FMR0.SRAF = 0: pattern
F72: Bit2 = 0 in every speech channel

TM
AIS (blue alarm) is indicated (FRS0.AIS) when two or less zeros
in the received bit stream are detected in a time interval of 12
frames (F4, F12, F72) or 24 frames (ESF).
AIS (blue alarm) detection is only enabled when FALC56 is in
asynchronous state. The alarm is indicated (FRS0.AIS) when
– three or less zeros within a time interval of 12 frames (F4,
– five or less zeros within a time interval of 24 frames (ESF)
Bit2 = 0 in every speech channel
– FMR0.SRAF = 1: FS-bit of frame 12 is forced to “1”
