Each TP is associated with a logical unit (LU) of type 6.2. The LU allows the TP to access the network. Several TPs can be associated with the same LU.

A partner TP can invoke another TP, which, in turn, invokes another TP, and so on. In the following figure, TP A invokes TP B and TP B invokes TP C.
