5 Test Purposes (TP)
5.1 Introduction
For each test requirement a Test Purpose (TP) is defined.
5.1.1 Test Purpose (TP) naming convention
For each test requirement a Test Purpose (TP) is defined.
All test purposes belong to the main group ISUP_SIP_Interworking. Groups are organized according to the test suite
structure (TSS). Each test purpose is presented in a separate table. The first row of the table contains the following
items:
• TP Identifier of the test purpose.
• SIP reference the reference to the requirement in the DSS1 layer 3 Recommendation, which led to the TP.
• ISUP reference the reference to the requirement in the interworking specification and the requirement in the
SIP-UP Recommendation, which led to the TP.
