XCA Major Node VTAM Gen Requirements
When setting the FEP-4600 up as XCA (External Communications Adapter) interface for
PU 2.1 traffic, the gen requirements are also simple. The XCA interface provides a pipe
through which PU 2.1 traffic flows between the external network and the channel. If you
already have Switched Major Node definitions in use for your PU 2.0 platforms coming
through the 3745’s Token Ring adapters, then you should not have to make any changes
to those definitions at all. You will need to define at least one XCA Major Node
definition for each network adapter that will be used to provide access for the
downstream PUs. Each network adapter on the FEP-4600 can support up to eight XCA
definitions, allowing support for up to 2040 DSPUs through each adapter.
