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
NNetwork
= 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.

NOTE: Text in italics will not appear in TPs and text between <> is filled in for each TP and may differ from one
TP to the next.
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 subclause are as specified in EN 300 286-2 [2] unless indicated otherwise by another
numbered reference.
