The UAPs that can be tested by the UAP tester facilities are SUPs, SPPs, and MHPs. The purpose of testing varies depending on the particular type of UAP tester facility.

If a CUP, which is a UAP used with the OpenTP1 client facility (TP1/Client), requests an SPP for service, it can start the SPP in test mode.

UAPs that handle offline works cannot be tested by the UAP tester facilities.

For details on the UAP tester facilities, see the OpenTP1 Tester and UAP Trace User's Guide.
