Abstract
The channel protection facility in a two-fiber bi-directional line switched ring network may be significantly enhanced by protecting the service channels in one of the fibers with corresponding protection channels in the other fiber and vice-versa. Thus, if a failure occurs such that the content of the service channels cannot be forwarded to an upstream point, then, without having to perform a wavelength conversion function, the service channels may be substituted for the protection channels in the other fiber and forwarded to the upstream point in the opposite direction via the ring network.
