Is this host the OLU host?

         If Yes:

               What is the sense code for ISTAPNCP in the IST895I message? If it is a sense code other then 08400007
               then investigate the meaning of the specific sense code.
               For sense 08400007 continue on to the next question.                                               

               If ISTAPNCP is not in the IST895I message:    

                   If the VTAM Start option SORDER is coded to ADJSSCP then you must include ISTAPNCP in the
                   ADJSSCP table. If the DLU name in the IST664I message group indicates an ALIAS  DLU then  code
                   ISTAPNCP in the DEFAULT ADJSSCP table. If the IST664I indicates a REAL DLU and you have a Network
                   specific ADJSSCP table coded for that NETID then you need to include ISTAPNCP in that table.

         If No:
              
                 If the session request came into this host from an End Node there will be no messages issued on this host unless
                 the search enters the subarea network from this host. If this is an ICN and the session request came in from
                 subarea then as long as SIRFMSGFSIRFMSG and ESIRFMSG message start options are set to ALLSSCP
                 you will see these messages.

Is this Host a Border Node?

        If Yes then continue to the Border Node Section: 

        If No then move to host in this network that is performing the Border Node Function for the DLU and then continue to the
        Border Node Section.
