          Appeal No. 2004-1561                                                        
          Application No. 09/631,474                                                  

               The disclosed invention relates to a method and apparatus              
          for sending control information between a control unit and at               
          least one of a plurality of cascaded units.  The control                    
          information is sent via a common control channel over a time-               
          multiplexed communications link.  The common control channel                
          comprises a plurality of consecutive timeslots of a time-                   
          multiplexed frame.                                                          
               Claim 45 is illustrative of the claimed invention, and it              
          reads as follows:                                                           
               45.        A method for sending control information between            
                    a control unit and at least one of a plurality of                 
                    cascaded units (CU) comprising:                                   
                    generating an downlink message of a predetermined                 
                         length comprising a CU identifier and control                
                         information, wherein said CU identifier                      
                         corresponds to a designated CU;                              
                    sending said downlink message to said designated CU               
                         using a common control channel over a time-                  
                         multiplexed communications link, said common                 
                         control channel comprising a plurality of                    
                         consecutive timeslots of a time-multiplexed                  
                         frame; and                                                   
                    processing said downlink message at said designated CU.
