2.4.4
Decoding is done in the reverse manner of coding. The received blocks of 3 ternary
symbols are converted into blocks of 4 bits. The decoding algorithm is given in
As in the encoding table, the left hand symbol of each block (both binary and ternary) is
the first bit and the right hand is the last. If a ternary block "0 0 0" is received, it is decoded
to binary "0 0 0 0". This pattern usually occurs only during deactivation.
