DFP:
The DFP bit controls the insertion of a single bit error continuously in the most significant
bit (bit 1) of the A1 section overhead framing byte. When DFP is set to logic one, the A1
bytes are set to 0x76 instead of 0xF6.
DBIP8:
The DBIP8 bit controls the insertion of bit errors continuously in the section BIP-8 byte
(B1). When DBIP8 is set to logic one, the B1 byte is inverted.
DLOS:
The DLOS bit controls the insertion of all zeros in the STS-3c/STM-1 stream. When DLOS
is set to logic one, the transmit stream is forced to 0x00.
