A method of forward error control is disclosed in which a transmitter receives data from an input device and from it creates one or more original codewords that are transmitted onto each of two physically distinct telecommunications channels. The reason that two copies of the original codeword are transmitted to the receiver via physically distinct channels is to increase the robustness of the overall effective telecommunications channel between the transmitter and the receiver, and to minimize the elapsed time between when the transmitter transmits the original codeword and when receiver has a final estimate of the original codeword available for output. The illustrative embodiment comprises: transmitting a first copy of an original codeword from a transmitter to a receiver via a first point-to-point telecommunications channel; transmitting a second copy of the original codeword from the transmitter to the receiver via a second point-to-point telecommunications channel; receiving at the receiver a first estimate of the original codeword from the first point-to-point telecommunications channel; and constructing a final estimate of the original codeword based on the first estimate of the original codeword.
