(Item 008407) Correct DLUR REQDISCONT processing                                
------------------------------------------------                                
When a DLUR currently receives a REQDISCONT request from a downstream           
PU (DSPU), it converts the request into a REQDACTPU request and sends           
it to the DLUS.  It does not return a RSP(REQDISCONT) to the DSPU.              
It appears that in the same situation in a subarea environment, a               
RSP(REQDISCONT) is returned to the DSPU (for subarea the response is            
built by the subarea SSCP and is forwarded to the DSPU by the NCP BF).          
                                                                                
Problems have been reported by customers involving DSPUs hanging                
because a RSP(REQDISCONT) was not sent by the DLUR.  The DLUR                   
architecture must be updated to direct the DLUR to build and send a             
RSP(REQDISCONT) to the DSPU upon receipt of the RSP(REQDACTPU) from the         
DLUS.
