You can configure the iSeries™ system to communicate with a host system by matching iSeries system parameters. Another option for iSeries system users is Dependent LU Requester Support (DLUR). DLUR allows dependent secondary logical units (LU 0, 1, 2, and 3) an entry point into the APPN network. DLUR support gives the appearance of having an adjacent connection to VTAM®, but allows traversing the APPN network through intermediate nodes. For more information on these options to communicate with host systems, see the following:
