A method and apparatus for encoding a bit sequence as a symbol, suitable for transmission over pots wiring (14), are described. The symbol has a duration indicative of the bit sequence, this time duration be determined by first and second delimiters (92A) and (92B) respectively. The method commences upon the receipt of a bit sequence at an encoder (46A) thereafter, a symbol, having a duration indicative of the bit sequence, is identified. The symbol is characterized in that it includes a buffer portion (50A) and an encoding portion (46A). The buffer portion (50A) is of sufficient duration to allow reflections, generated by propagation of the first delimiter (92A) of the symbol on the pots wiring (14), to decay to a predetermined level before propagation of the second delimiter (92B).
