Error Analysis
Possible errors that can be detected are:
C-Bit (Control-Bit): A C-Bit error indicates that the three C-bits reserved
to control bit stuffing are different of "111" and "000".
F-Bit (Framing-Bit): A F-Bit error indicates that the frame alignment
pattern received is different of "1001".
P-Bit (Parity-Bit): A P-Bit error indicates that the P-Bits does not match
the parity of all the information bits following the first X-Bit of the
previous DS3 frame.
FEBE (Far-End Block Error): A FEBE is detected when the three FEBE
bits reserved for framing or parity error detection contain the "000"
pattern.
