Errors
 B3 (BIP-8, Bit-Interleave Parity - 8 bits) for SONET/SDH, indicates a high
order path parity error by performing an even-parity check over all bits
of the previous SPE (SONET) / VC-N (SDH).
 B3 (BIP-8, Bit-Interleave Parity - 8 bits) for WIS, indicates a Path parity
error by performing a routine even-parity check over all Path bits of the
previous SPE excluding the LOH and SOH.
 BEI (Backward Error Indication) for FlexO, indicates that there is
interleaved block in error detected by the corresponding ODU path
monitoring sink using the BIP-8 code.
 BEI (Backward Error Indication) for FlexO OTUCn, indicates that SM
BEI errors are received from the DUT (value 0 to 8).
