Foreword
This ETSI Guide (EG) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document is part 1 of a multi-part EG covering Integrated Services Digital Network (ISDN); Network
Integration Testing (NIT); ISDN/PSTN end-to-end testing, as identified below:
Part 1: "Test Suite Structure and Test Purposes (TSS&TP) specification";
Part 2: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT)
proforma for the network".
Introduction
The present document contains the Test Suite Structure and Test Purposes (TSS&TP) list developed in the EURESCOM
project P613 "Methodology and tools for ISDN Network Integration and Traffic Route Testing" for testing the
international European ISDN, covering Network Integration Testing (NIT) between ISDN-ISDN, ISDN-PSTN and
PSTN-ISDN networks. The objective is to verify the level of international end-to-end support of ISDN services. Both
bearer services (and associated teleservices) and supplementary services are checked for interworking capability and
compatibility, in the international European ISDN.
The European ISDN is made up by connecting the different national networks and End-to-end NIT covers all the testing
activities necessary to assess the correct behaviour of the interconnected network from the point of view of access
interfaces, network side.
Included are the test purposes developed in the preceding EURESCOM project P613 with additional test purposes for
the basic call and supplementary services that are supported by the international ISUP versions 1 and 2, and test
purposes for end-to-end performance to check B-channel stability and quality. The performance objectives take into
consideration the definitions present in the relevant ITU-T Recommendations and adopt the 24 hours measurement
period and target values used by ETSI for ONP 64 kbit/s leased line applications.

1 Scope
The present document 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 for the pan-European Integrated Services Digital Network (ISDN)
as provided by European public telecommunications operators by means of the Digital Subscriber Signalling System
No. one (DSS1) protocol, for Network Integration Testing (NIT) covering the end-to-end support of ISDN services.

6 Test Purposes
6.1 Introduction
For each test requirement a Test Purpose is defined.
6.1.1 Test purpose naming convention
The Test Purposes are identified by a six figure numbering scheme were the first figure identifies the Test Group,
followed by a three figure number for subgroup and a two figures serial number, starting at 01, within each
group/subgroup. Groups are organized according to the TSS. See table 1 below.
Table 1: Test Purpose Identifier naming convention scheme
Identifier: TC
: 1 digit field representing group reference according to TSS
1 = ISDN-ISDN/Basic_call
2 = ISDN-ISDN/Supplementary_services
3 = ISDN-ISDN/B-channel
4 = ISDN-PSTN/Basic_call
5 = ISDN-PSTN/Supplementary_services
6 = PSTN-ISDN/Basic_call
7 = PSTN-ISDN/Supplementary_services
: 3 digit field representing sub group reference according to TSS
= sequential number (01-99)
6.1.2 Source of test purpose definition
The Test Purposes are based on EN 300 403-1 [1] and the applicable standards for supplementary services.
6.1.3 Test purpose structure
The Test Purposes are formatted as tables using the format shown in the following figure. The text in bold shows the text
which is always present. The normal text provides explanation for each field.

Comments:
6.1.4 Test strategy
As the base standards contained no explicit requirements for testing, the Test Purposes were generated as a result of an
analysis of the base standards and PICS. The criteria applied included 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 Test Purpose is not considered.

6.1.5 End-to-end performance objectives
ITU-T Recommendation G.821 [24] define performance objectives to be meet for each direction of a N x 64 kbit/s
(1 ≤ N < 32) circuit-switched connection used for voice or data-type traffic. The ITU-T Recommendation G.821 [24]
error performance objectives for international ISDN connections are presented in the following table 3. A measuring
period of one month is suggested as a reference.
Table 3: ITU-T Recommendation G.821 [24] error performance objectives
Performance parameter Objective
SESR Fewer than 0,2% of one-second intervals to have a bit-error ratio worse than 1
x 10-3
ESR Fewer than 8% of one-second intervals to have any errors
ETS 300 289 [23] specifies the technical requirements (and test principles) for the connection characteristics of
ONP 64 kbit/s digital unrestricted leased lines with octet integrity. The end-to-end performance objectives are derived
from ITU-T Recommendation G.821 [24]: the test values have been transformed to fit a measuring period of 24 hours
instead of one month, taking also in consideration the circuit configurations relevant for Europe (see ETS 300 289 [23]
Annex B).
For the ISDN bearer services "unrestricted digital information" and "unrestricted digital information with
tones/announcements", the connection characteristics of the B-channel established between users may be considered
equivalent in service to a ONP 64 kbit/s digital unrestricted leased line (D64U), because the ISDN circuit connection
provides
