Simple-mode Link with Default Session Parameters

You can create a simple-mode link definition by specifying the minimum amount of information, which is:

The region name of the remote region
The one- to four-character MSGID used as a prefix on ROF messages received from the remote region

All other session parameters are allowed to default as dictated by the access method when sessions are established.

This way of defining regions to each other is appropriate in the following environments:

There is a single physical network route providing the communication path between the two regions.
There is no FTS traffic between the two CPUs.
There is FTS traffic between the two regions, but its effect on other traffic sharing the network path between the two is of no concern or has been minimized.
The level of VTAM in use does not support multiple network paths between subareas.
