Coding in 100VG-AnyLAN
A 5B/6B coding scheme in which five data bits are encoded into six-bit codewords is used in conjunction with offsetting the data on different channels by three bits in quartet signaling. It provides the level of error detection necessary, produces a signal balanced within narrow limits, and restricts strings of consecutive 0s or 1s to a maximum length of 6. It is also efficient.
