(Item 008494) -RSP(REQDACTPU) DLUR processing                                   
---------------------------------------------                                   
The current DLUR architecture is unclear as to what a DLUR should do            
upon receipt of a -RSP(REQDACTPU).                                              
                                                                                
The solution is to add a new section, 5.6.3.3 "-RSP(REQDACTPU)         
DLUR Processing," to the DLUR architecture reference; the section will          
include:                                                                        
                                                                                
    When the DLUR receives a negative response to REQDACTPU,                    
    regardless of the cause type, it will reset the PU and its                  
    associated LUs.  This may include:                                          
                                                                                
       - resetting the LU-LU sessions, creating and sending SESSENDs            
                                                                                
       - resetting the SSCP-LU sessions                                         
                                                                                
       - resetting the SSCP-PU session                                          
                                                                                
       - deactivating the DLC if there was no outage                            
                                                                                
    All of the -RSP(REQDACTPU) cases will be handled as the                     
    +RSP(REQDACTPU) downstream PU outage case, i.e., no DACTLUs or              
    DACTPUs will be built and sent to the downstream devices.
