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 theuser (see table 1).Table 1: TP identifier naming convention schemeIdentifier:__=supplementary service:e.g. "HOLD"=type of IUT:UUserNNetwork=group2 digit field representing group reference according to TSS=sequential number(001-999)6.1.2Source of TP definitionThe TPs are based on ETS 300 141-1 [1], clauses 9, 10 and 14.6.1.3TP structureEach TP has been written in a manner which is consistent with all other TPs. The intention of this is tomake the TPs more readable and checkable. A particular structure has been used and this is illustrated intable 2. This table should be read in conjunction with any TP, i.e. use a TP as an example to fullyunderstand the table.SIST ETS 300 141-5:1997

1 Scope
This fifth part of ETS 300 141 specifies the Test Suite Structure and Test Purposes (TSS&TP) for the
Network side of the T reference point or coincident S and T reference point (as defined in ITU-T
Recommendation I.411 [7]) of implementations conforming to the stage three standard for the Call Hold
(HOLD) supplementary service for the pan-European Integrated Services Digital Network (ISDN) by
means of the Digital Subscriber Signalling System No. one (DSS1) protocol, ETS 300 141-1 [1].
A further part of this ETS specifies the Abstract Test Suite (ATS) and partial Protocol Implementation
eXtra Information for Testing (PIXIT) proforma based on this ETS. Other parts specify the TSS&TP and
the ATS and partial PIXIT proforma for the User side of the T reference point or coincident S and
T reference point of implementations conforming to ETS 300 141-1 [1].

6 Test Purposes (TP)
6.1 Introduction
For each test requirement a TP is defined.
6.1.1 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. "HOLD"
= type of IUT: U User
N Network
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)
6.1.2 Source of TP definition
The TPs are based on ETS 300 141-1 [1], clauses 9, 10 and 14.
6.1.3 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.
6.1.4 Test strategy
As the base standard ETS 300 141-1 [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 ETS 300 141-2 [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.

6.2 Network TPs for HOLD
All PICS items referred to in this subclause are as specified in ETS 300 141-2 [2] unless indicated
otherwise by another numbered reference. Where not stated otherwise, PICS item R 1 ("support the
HOLD supplementary service") is required to be supported.
6.2.1 Network (S/T)
Selection: IUT supports coincident S and T reference point procedures. PICS: R 3.1.
