Abstract

A method for providing fault tolerant transmission of electrical signals through a transmission device. A number of redundant signals are transmitted through a transmission device, wherein the number of redundant signals per original signal varies dynamically in accordance with selected conditions. These selected conditions are typical of whether the transmission device, typically a switching network, are in normal or overflow operation. Putatively identical signals at corresponding outputs of the transmission device are then compared and at least one correct output signal is generated therefrom.
