COFA
RIR1.7
Change of Frame Alignment. Set when the last resync resulted
in a change of frame or multiframe alignment.
8ZD
RIR1.6
Eight-0 Detect. Set when a string of at least eight consecutive 0s
(regardless of the length of the string) have been received at
RPOSI and RNEGI.
16ZD
RIR1.5
Sixteen-0 Detect. Set when a string of at least 16 consecutive 0s
(regardless of the length of the string) have been received at
RPOSI and RNEGI.
RESF
RIR1.4
Receive Elastic Store Full. Set when the receive elastic store
buffer fills and a frame is deleted.
RESE
RIR1.3
Receive Elastic Store Empty. Set when the receive elastic store
buffer empties and a frame is repeated.
SEFE
RIR1.2
Severely Errored Framing Event. Set when 2 out of 6 framing
bits (Ft or FPS) are received in error.
B8ZS
RIR1.1
B8ZS Code Word Detect. Set when a B8ZS code word is
detected at RPOS and RNEG independent of whether the B8ZS
mode is selected or not via CCR2.6. Useful for automatically
setting the line coding.
FBE
RIR1.0
Frame Bit Error. Set when a Ft (D4) or FPS (ESF) framing bit
is received in error.
