All SME invocations are shown, and the alias selection invocations are described after the figure.

2: VTAM® passes the DLU alias name, the OLU real name, the associated LU real names, and the logon mode name as known in the OLU's network. The alias selection function has the option of returning the DLU real name, the network ID of the DLU real name, the owning SSCP of the DLU, the OLU and associated LU alias names as known in the DLU network, and the logon mode name as known in the DLU network.
6: Same description as number 2.
10: VTAM requests translations from NETA to NETB for the OLU alias name, the associated LU alias names, the logon mode name, the COS name, and to translate the COS name from NETB to NETA.
13: VTAM drives the exit routine to translate the COS name from NETB to NETA. No attempt is made to translate the associated LU names because this host has already attempted to translate them.
