FOOF:
The FOOF bit controls the framing of the RSOP. When a logic one is written to FOOF, the
RSOP is forced out of frame at the next frame boundary. The FOOF bit is a write only bit,
register reads may yield a logic one or a logic zero.
DDS:
The DDS bit is set to logic one to disable the descrambling of the STS-3c/STM-1 stream.
When DDS is a logic zero, descrambling is enabled.
BLKBIP:
The BLKBIP bit position enables the accumulating of section BIP word errors. When a
logic one is written to the BLKBIP bit position, one or more errors in the BIP-8 byte result
in a single error being accumulated in the B1 error counter. When a logic zero is written to
the BLKBIP bit position, all errors in the B1 byte are accumulated in the B1 error counter.
