             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.
