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
0 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 1 is written to YEL, the PLCP yellow alarm signal is
transmitted.
DFEBE:
The DFEBE bit controls the insertion of far end block errors in the PLCP
frame. When DFEBE is written with a logic 1, a single FEBE is inserted each
PLCP frame. When DFEBE is written with a logic 0, 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 1, a single BIP error is
inserted in each PLCP frame. When DB1 is written with a logic 0, 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 1, a single bit error is inserted in each A1
