Defining the network

The tasks include:

• Defining the names of the terminals
• Defining the terminal device types
• Specifying optional parameters, such as buffer sizes

The IMS network consists of static and dynamic terminals (ETO and LU 6.2 devices). You do not need to define your ETO or LU 6.2 devices to IMS.

Although only static terminals in the IMS network are defined by system definition macros, both static and dynamic terminals must be defined to VTAM®. You must coordinate several aspects of the IMS requirements with parameters that are specified during VTAM network generation. The following topics highlight those coordination activities, but do not attempt to relate the separate IMS system definition in a detailed way with the series of VTAM and NCP definitions.
