LU Connections

An LU is the addressable connection point into an SNA network with which an end-user can send and receive messages. An LU is a set of rules and responsibilities. LUs can be either dependent or independent, and each LU type is associated with a protocol (for example, LU 0, LU 2, LU 3, or LU 6.2). CA XCOM Data Transport only supports LU type 6.2.

The LU provides a connection into SNA for the end-user, which may be either an individual or a transaction program (for example, CA XCOM Data Transport). It allows end-users to communicate with each other and with other network addressable units (NAUs) in the network.
