Abstract
An encoding scheme relies on a d.c. balanced code wherein each message to be transmitted is sent as a plurality of symbols, each symbol having six bits, three ones and three zeros. Out of the twenty combinations of balanced six-bit codes, two codes are reserved to operate as control tokens, being 010101 and 01010. Because of the particular format of the symbols, control tokens can be easily detected. Furthermore, they can be combined in longer bit sequences for use as initialisation and disconnect sequences.
