enabled to use the first of the framing algorithms where all the A1 framing bytes and all the A2 framing bytes are examined. This algorithm examines all 48 bits of the STS-3c (STM-1/AU3/AU4) framing pattern.

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 de-scrambling of the STS-3c (STM-1) stream. When DDS is a logic zero, de-scrambling is enabled.

BIPWORD:

The BIPWORD bit position enables the accumulating of section block BIP errors. When a logic one is written to the BIPWORD bit position, one or more errors in the BIP-8 byte result in a single error accumulated in the B1 error counter. When a logic zero is written to the BIPWORD bit position, all errors in the B1 byte are accumulated in the B1 error counter.

Reserved:

The reserved bits must be programmed to logic zero for proper operation.
