VTAM Definitions
As for the VTAM definitions, you would define a standard Channel Adapter PU4
definition for each of the four subchannels. One might look like this:
VISBLD VBUILD TYPE=CA
VISGRP GROUP LNCTL=CTCA,ISTATUS=ACTIVE,REPLYTO=25,MIH=YES
VISLN LINE ADDRESS=C30,MAXBFRU=16
VISPU1 PU PUTYPE=4,TGN=1
Remember to match up your Transmission Groups numbering between each VTAM
definition (TGN option) and the value assigned in the FEP-4600 for that interface. The
value for MAXBFRU should normally be set to a value of 16. This ensures that the
maximum amount of data can be moved in each transfer.
Remote Connections
Remote connections between two FEP-4600s can be achieved by implementing the SNI
over IP feature of the FEP-4600. This option allows you to select to encrypt the
connection adding security.
