Abstract
A method and outage recognition device for use with a redundantly designed optical transmission system having at least two receiver circuits at each station of the system with each receiver circuit having an input, an output and a separate transmission channel connected to the input characterized by the recognition device and method determining an outage of either one of the transmission channels by applying an output of each of the receiver circuits to a means for recognizing outages in the channel and determining the outage in the transmission channel by the occurrent data independent of statistical phase positions of the data in each channel. In a specific embodiment of the device, various logic elements are interconnected in a manner so that they not only reliably identify an outage of a channel but also indicate which channel has failed.
