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. "GFP"=type of IUT:UUserNNetwork=clause1 or 2 character field representing a clause number fromETS 300 196-1 [1]=group2 digit field representing group reference according to TSS=sequential number(001-999)6.1.2Source of TP definitionThe TPs are based on ETS 300 196-1 [1].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 300 196-5:1998

In these cases theTP includes the requirement to ensure that the IUT has entered this particular final call state. Ensuringthat the IUT is in a particular call state shall be realized by following the procedures described insubclause 5.8.10 of ETS 300 102-1 [7]. According to these procedures, the IUT on receipt of a STATUSENQUIRY message, shall respond with a STATUS message indicating, in the third octet of the Call stateinformation element, the current call state of the IUT. This exchange of messages is not mentionedexplicitly in each TP but is considered to be implicit in the reference to the final call state. This way ofphrasing the TPs has been used to avoid over-complicating the text and structure of the TPs and toimprove the readability.SIST ETS 300 196-5:1998

1 Scope
This fifth part of ETS 300 196 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 [6]) of implementations conforming to the stage three standard for the generic
functional protocol for the support of supplementary services for the pan-European Integrated Services
Digital Network (ISDN) by means of the Digital Subscriber Signalling System No. one (DSS1) protocol,
ETS 300 196-1 [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 300 196-1 [1].

6 TSS&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. "GFP"
= type of IUT: U User
N Network
= clause 1 or 2 character field representing a clause number from
ETS 300 196-1 [1]
= 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 300 196-1 [1].
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 300 196-1 [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 300 196-2 [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.
6.1.5 Test of call states
Many TPs include a reference to the IUT's final call state after the realization of the TP. In these cases the
TP includes the requirement to ensure that the IUT has entered this particular final call state. Ensuring
that the IUT is in a particular call state shall be realized by following the procedures described in
subclause 5.8.10 of ETS 300 102-1 [7]. According to these procedures, the IUT on receipt of a STATUS
ENQUIRY message, shall respond with a STATUS message indicating, in the third octet of the Call state
information element, the current call state of the IUT. This exchange of messages is not mentioned
explicitly in each TP but is considered to be implicit in the reference to the final call state. This way of
phrasing the TPs has been used to avoid over-complicating the text and structure of the TPs and to
improve the readability.
