Description
Loss of Synchronization.
Incorrect Running Disparity value for
an 8B/10B encoded block.
Illegal 10-bit code in an 8B/10B
encoded block.
The 4-bit O code in a 64B/66B
encoded block contains an illegal
value.
Any control character in a 64B/66B
encoded block contains an illegal
value.
The Sync Field in a 64B/66B encoded
block has an illegal value (the first
two bits of the block have a bit value
of 00 or 11).
The Block Type field in a 64B/66B
encoded block contains a reserved
value.
A Reserved Bit field in 64/66b coding
contains a 1. Reserved Bit fields in
the block structure are expected to be
sent as 0 (and ignored by the
receiver).
Parity value of the FEC block is not
correct.
