Abstract
A method for reducing bit error in a digital communications system including the step of identifying whether a data or information word was correctly switched through a network having at least three switching levels after the data word has been switched by undertaking a parity bit check as well as a bit by bit comparison of the bits in the data word, and an apparatus configured to perform the method. Bit errors are corrected either on the basis of majority decision or by a Statistical evaluation of the bit error rates of the various switching levels of the switching network.
