LSS[2:0]
The LSS[2:0] bits control the value inserted in the link status signal code bit positions of the
path status octet (G1). These bits should be written with logic zero when implementing an
ATM Forum UNI-compliant DS3 interface.
YEL
The YEL bit controls the yellow signal bit position in the path status octet (G1). When a logic
one is written to YEL, the PLCP yellow alarm signal is transmitted.
DFEBE
The DFEBE bit controls the insertion of FEBEs in the PLCP frame. When DFEBE is written
with a logic one, a single FEBE is inserted each PLCP frame. When DFEBE is written with a
logic zero, FEBEs are indicated based on receive PLCP bit interleaved parity errors.
DB1
The DB1 bit controls the insertion of bit interleaved parity (BIP) errors in the PLCP frame.
When DB1 is written with a logic one, a single BIP error is inserted in each PLCP frame.
When DB1 is written with a logic zero, the bit interleaved parity is calculated and inserted
normally.
DAFRM
The DAFRM bit controls the insertion of frame alignment pattern errors. When DAFRM is
written with a logic one, a single bit error is inserted in each A1 octet, and in each A2 octet.
When DAFRM is written with a logic zero, the frame alignment pattern octets are inserted
normally.
