PRDI10
The path remote defect indication detection (PRDI10) bit selects the path RDI and path
ERDI persistence. When PRDI10 is set to logic 1, path RDI and path ERDI are accepted
when the same pattern is detected in bits 5,6,7 of the G1 byte for ten consecutive frames.
When PRDI10 is set to logic 0, path RDI and path ERDI are accepted when the same
pattern is detected in bits 5,6,7 of the G1 byte for five consecutive frames.
FSBIPDIS
The disable fixed stuff columns during BIP-8 calculation (FSBIPDIS) bit controls the path
BIP-8 calculation for an STS-1 (VC-3) payload. When FSBIPDIS is set to logic 1, the fixed
stuff columns are not part of the BIP-8 calculation when processing an STS-1 (VC-3)
payload. When FSBIPDIS is set to logic 0, the fixed stuff columns are part of the BIP-8
calculation when processing an STS-1 (VC-3) payload.
PBIPEBLKACC
The path block BIP-8 errors accumulation (PBIPEBLKACC) bit controls the accumulation
of path BIP-8 errors. When PBIPEBLKACC is set to logic 1, the path BIP-8 error
accumulation represents block BIP-8 errors (a maximum of 1 error per frame). When
PBIPEBLKACC is set to logic 0, the path BIP-8 error accumulation represents BIP-8 errors
(a maximum of 8 errors per frame).
PBIPEBLKREI
The path block BIP-8 errors (PBIPEBLKREI) bit controls the path REI errors returned to
the THPP. When PBIPEBLKREI is set to logic 1, the path REI is updated with block BIP-8
errors (a maximum of 1 error per frame). When PBIPEBLKREI is set to logic 0, the path
REI is updated with BIP-8 errors (a maximum of 8 errors per frame).
B3EBLK
The serial path block BIP-8 errors (B3EBLK) bit controls the indication of path BIP-8
errors on the B3E serial output. When B3EBLK is set to logic 1, B3E outputs block BIP-8
errors (a maximum of 1 error per frame). When B3EBLK is set to logic 0, B3E outputs
BIP-8 errors (a maximum of 8 errors per frame).
PREIBLKACC
The path block REI errors accumulation (PREIBLKACC) bit controls the accumulation of
path REI errors from the path status (G1) byte. When PREIBLK is set to logic 1, the
extracted path REI errors are interpreted as block BIP-8 errors (a maximum of 1 error per
frame). When PREIBLK is set to logic 0, the extracted path REI errors are interpret as
BIP-8 errors (a maximum of 8 errors per frame).
