Appeal No. 2007-1287 Application No. 10/161,274 INVENTION The invention is directed to optical communication networks. The invention relates to providing information as to which channels in an optical signal are active. See page 3 of Appellants’ Specification. Claim 1 is representative of the invention and reproduced below: 1. A method for optical supervisory signaling, comprising: determining, for each one of a plurality of data channels serviced by a first optical communication node: a wavelength channel status value indicating whether the channel has been provisioned; a wavelength channel failure value indicating whether a failure has been detected on the channel; and a wavelength channel lit value indicating whether the channel is active; and communicating the wavelength channel status value, the wavelength channel failure value, and the wavelength channel lit value to a second optical communication node.
