REMAIS (b3, E1-041H) is set to ‘1’.
set to ‘1’ automatically during loss of frame alignment or receiving AIS. The G706RAI (b0, E1-00EH) is used to select the conditions, under which the
Yellow Alarm signal will be transmitted automatically.
AUTORED:
automatically when Red Alarm is declared.
AUTOOOF:
automatically in the duration of loss of basic frame.

Bit No.
Type
This bit decides whether the received data should pass through or bypass the Receive Jitter Attenuation FIFO.
= 0: The received data pass through the RJAT FIFO.
= 1: The RJAT FIFO is bypassed. The delay is reduced by typically 24 bits.
= 0: The Frame Processor operates normally.
= 1: Frame searching is disabled, the Receive CAS/RBS Buffer holds the signaling frozen, and Auto_OOF function, if enabled, will consider OOF
This bit decides whether to send Yellow Alarm signal automatically.
= 0: The automatic Yellow Alarm Transmission is disabled. It means that the RAI bit, the 3rd bit of NFAS frame, can only be transmitted when the
= 1: The automatic Yellow Alarm Transmission is enabled. It means that the RAI bit (the 3rd bit of NFAS frame) in the transmit data stream will be
This bit decides whether to start trunk conditioning (replacing data on RSDn with the data stored in the data trunk conditioning registers in RPLC)
= 0: The trunk conditioning is not activated automatically when RED (b3, E1-037 H) becomes ‘1’.
= 1: The trunk conditioning will be initiated automatically when the RED (b3, E1-037H) becomes ‘1’.
This bit decides whether to start trunk conditioning (replacing data on RSDn with the data stored in the data trunk conditioning registers in RPLC)
= 0: The trunk conditioning is not activated automatically when the OOFV (b6, E1-036 H) becomes ‘1’.
= 1: The trunk conditioning will be activated automatically when the OOFV (b6, E1-036 H) becomes ‘1’.

Each bit error in a 7-bit FAS pattern is counted as a single framing bit error.
One or more than one bit errors in a 7-bit FAS pattern is counted as a single framing bit error.
Each bit error in a 7-bit FAS pattern is counted as a single framing bit error, and a logic 0 in the second bit
of TS0 of NFAS is counted as a single bit error too.
An 8-bit Error Word is consisted of a 7-bit FAS pattern and the second bit of TS0 in the next NFAS frame.
One or more than one bit errors in this 8-bit Error Word is counted as a single framing bit error.
