Transparent Mode
Setting this bit enables the transparent mode:
– In transmit direction bit 8 of every FS/DL time-slot from the system
– In receive direction the framing bit is also forwarded to RDO and
Transmit Remote Alarm (Yellow Alarm)
If high, remote alarm is sent via PCM route. Clearing the bit will
remove 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 ‘1111 1111 0000 0000…’ in data
F72: bit2 = 0 in every speech channel
TM
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.
inserted in the FS/DL timeslot. Bit RDCF (bit 1 of FS/DL time-slot)
indicates a DL bit.
H
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 FALC54 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’
