          Application No. 08/477,238                                                  


          through a solid dielectric substrate.  Claim 22 is                          
          illustrative of the claimed invention, and it reads as                      
          follows:                                                                    
               22. An apparatus for reducing crosstalk in a connector                 
          circuit for communications systems, comprising:                             
               means for applying first and second pairs of                           
          substantially equal and opposite electrical signals to an                   
          electrical connector having first, second, third and fourth                 
          primary terminals arranged in a first ordered array with the                
          second and third primary terminals being between the first and              
          fourth primary terminals, having first, second, third and                   
          fourth secondary terminals arranged in a second ordered array,              
          and having circuit means for electrically coupling the first,               
          second, third and fourth primary terminals to the first,                    
          second, third and fourth secondary terminals, respectively, by              
          first, second, third and fourth conductive paths on a solid                 
          dielectric substrate connecting and connected to the first,                 
          second, third and fourth terminals, respectively;                           
               means for applying the first pair of substantially equal               
          and opposite electrical signals to the first and fourth                     
          primary terminals;                                                          
               means for applying the second pair of substantially equal              
          and opposite electrical signals to the second and third                     
          primary terminals;                                                          
               means for reactively coupling sections of the first and                
          third paths through solid dielectric substrate to cancel                    
          crosstalk induced in the connector circuit; and                             
               means for reactively coupling sections of the second and               
          fourth paths through the solid dielectric substrate to cancel
