Figure 1: Test suite structure 5 Test Purposes (TP) 5.1 Introduction For each test requirement a TP is defined. 5.1.1 TP naming convention TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS. Additional references are added to identify the actual test suite and whether it applies to the network or the user (see table 1). Table 1: TP identifier naming convention scheme
Identifier: __
= supplementary service: e.g. "UUS"
= type of IUT: U User N Network
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)
5.1.2 Source of TP definition The TPs are based on EN 300 286-1 [1]. 5.1.3 TP structure Each TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPs more readable and checkable. A particular structure has been used and this is illustrated in table 2. This table should be read in conjunction with any TP, i.e. use a TP as an example to fully understand the table. SIST EN 300 286-5 V1.4.1:2005

5.1.4 Test strategy As the base standard EN 300 286-1 [1] contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification EN 300 286-2 [2]. The criteria applied include the following: - only the requirements from the point of view of the T or coincident S and T reference point are considered; - whether or not a test case can be built from the TP is not considered. 5.1.5 Test of point-to-multipoint configurations In the case of a point-to-multipoint configuration several terminals may be attached to one basic access interface. Each terminal will use a different Connection Endpoint Suffix (CES). To reflect this in the TPs, the CES for which a message is received or sent (e.g. ".on receipt of an ALERTING message for CES1.") is named explicitly where this clarification is needed. 5.2 Network TPs for UUS All PICS items referred to in this clause are as specified in EN 300 286-2 [2] unless indicated otherwise by another numbered reference.
