Introduction
This configuration allows 253 TN3270 clients to access one application or monitor on one host.

Logical View

The TN3270 clients connect to IP address 10.14.20.34 (port 23), and can be TN3270 or TN3270E clients. The TN3270 clients should not specify a static logical unit (LU) name, but should specify (as usual) a 3270 terminal-type to emulate.
On the host side, the single physical unit (PU) devoted to TN3270 traffic is CAPPU1. A static terminal LU called CAP01L01 is defined in the switched major node definition, DIRPU2. It inherits the LU characteristics defined in the PU definition. This LU can be used by an incoming TN3270E session that specifies CAP01L01 as its desired LU.
Two printers also are attached to the CAPPU1 PU: one type 1 and one type 3 (named CAP01L02 and CAP01L03, respectively). In these examples, these LUs are run and defined by the Remote Spooling Communications Software (RSCS) Virtual Media (VM) printing application.
The remainder of the LUs are defined dynamically and have the characteristics assigned to them by way of the DDDLU exit (ISTEXCSD) run against the DDDLUGMP LUGROUP.

Router Configuration for VM/VTAM
This TN3270 router configuration has the channel connection plugged into Port 1 of the Channel Interface Processor (CIP) card. The XCA770 adapter definition is attached to the CIP Internal Token Ring LAN #1. Adapter 0 is bound for the external communications adapter (XCA) in virtual telecommunications access method (VTAM), while Adapter 1 is bound for TN3270 on CIP. The TN3270 server is active, and has one PU (CAPPU1) trying to connect. The CIP also has reserved the 10.14.20.32 subnet for exclusive use by tasks running on the CIP card.
