Errors
BEI (Backward Error Indication) for OTU, indicates that there is a SM
BIP-8 mismatch between the received value and locally computed
value (0 to 8).
BIP-2 (Bit-Interleave Parity - 2 bits) for SONET/SDH: For SONET,
indicates a parity error by performing a routine even-parity check over
all VT1.5 bytes of the previous frame of a composite signal
(VT1.5/VT2/VT6); for SDH, indicates a Low Order Path parity error by
performing a routine even-parity check over all bytes of the previous
VC frame.
BIP-8 (Bit Interleave Parity-8) for FlexO, indicates that there is a PM
BIP-8 mismatch between the received value and locally computed
value (0 to 8).
BIP-8 (Bit Interleave Parity-8) for FlexO OTUCn, indicates that there is a
SM BIP-8 mismatch between the received value and locally computed
value (0 to 8).
BIP-8 (Bit Interleave Parity-8) for ODU, indicates that there is a PM
BIP-8 mismatch between the received value and locally computed
value (0 to 8).
BIP-8 (Bit Interleave Parity-8) for ODU-TCM, indicates that there is a
TCM BIP-8 mismatch between the received value and locally
computed value (0 to 8).
