NAME AND DESCRIPTION
Change of Frame Alignment. Set when the last resync resulted
in a change of frame or multiframe alignment.
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.
16-Zero 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.
Receive Elastic Store Full. Set when the receive elastic store
buffer fills and a frame is deleted.
Receive Elastic Store Empty. Set when the receive elastic store
buffer empties and a frame is repeated.
Severely Errored Framing Event. Set when 2 out of 6 framing
bits (Ft or FPS) are received in error.
B8ZS Codeword Detect. Set when a B8ZS codeword 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.
Frame Bit Error. Set when a Ft (D4) or FPS (ESF) framing bit
is received in error.
