COFA
RIR1B.7
Change of Frame Alignment. Set when the last resync
resulted in a change of frame or multiframe alignment.
8ZD
RIR1B.6
Eight Zero Detect. Set when a string of at least eight
consecutive zeros (regardless of the length of the string) have
been received at RPOSIB and RNEGIB.
16ZD
RIR1B.5
Sixteen Zero Detect. Set when a string of at least sixteen
consecutive zeros (regardless of the length of the string) have
been received at RPOSIB and RNEGIB.
RIR1B.4
Not Assigned. Could be any value when read.
RIR1B.3
Not Assigned. Could be any value when read.
SEFE
RIR1B.2
Severely Errored Framing Event. Set when 2 out of 6
framing bits (Ft or FPS) are received in error.
B8ZS
RIR1B.1
B8ZS Code Word Detect. Set when a B8ZS code word is
detected at RPOSIB and RNEGIB independent of whether the
B8ZS mode is selected or not via CCR2.6. Useful for
automatically setting the line coding.
FBE
RIR1B.0
Frame Bit Error. Set when a Ft (D4) or FPS (ESF) framing
bit is received in error.
