DFERR
The DFERR bit selects whether the framing pattern is corrupted for diagnostic purposes.
When DFERR is logic one, the framing pattern inserted into the output data stream is
inverted. When DFERR is logic zero, the unaltered framing pattern inserted into the output
data stream.
CPERR
The CPERR bit enables continuous generation of BIP-8 errors for diagnostic purposes. When
CPERR is logic one, the calculated BIP-8 value is continuously inverted according to the
error mask specified by the BIP-8 Error Mask Register and inserted into the G.832 EM byte.
When CPERR is logic zero, the calculated BIP-8 value is altered only once, according to the
error mask specified by the BIP-8 Error Mask Register, and inserted into the EM byte.
PYLD&JUST
The PYLD&JUST bit selects whether the justification service bits and the tributary
justification bits in framing modes G.751 is indicated as overhead or payload. When
PYLD&JUST is logic one, the justification service bits and the tributary justification bits are
indicated as payload. When PYLD&JUST is logic zero, the justification service and tributary
justification bits are indicated as overhead. For G.751 ATM applications, this bit must be set
to logic one for correct cell mapping.
