          Appeal No. 1997-3129                                                        
          Application No. 08/301,743                                                  

               Turning to a consideration of dependent claims 2, 3, 15,               
          16, 18, and 20, we sustain the 35 U.S.C.  103 rejection of                 
          these claims as well.  We agree with the Examiner that the                  
          transceiver, counter, and decoder circuitry of dependent                    
          claims 2, 3, 16, and 18 is suggested by the circuitry                       
          illustrated in Figures 5a and 5b of Sauerwald.  Similarly, we               
          find that the test pattern and signature register features of               
          claims 15 and 20 are suggested at column 9, lines 28-65 and                 
          column 10, lines 60-68, respectively, of Sauerwald.                         
               We next turn to a consideration of dependent claims 4-10,              
          12, 13, and 19 and note that, while we found Appellants’                    
          arguments to be unpersuasive with respect to claims 1-3, 11,                
          14-18, and 20, we reach the opposite conclusion with respect                
          to dependent claims 4-10, 12, 13, and 19.  Dependent claim 4,               
          upon which claims 5-8 depend, 12, 13, and 19 are directed to                
          sensing circuitry which determines the establishment of a data              
          link between data transceivers.  While the Examiner recognizes              
          that Sauerwald has no disclosure of such feature, the Examiner              
          nevertheless concludes (Answer, page 5) that the skilled                    
          artisan would have found it obvious to provide such a feature.              
          The Examiner, however, has provided no support on the record                

                                          9
