Overview

SIST ETS 300 347-7:1997 defines the Test Suite Structure and Test Purposes (TSS&TP) for the data link layer of the V5.2 interface at the digital Local Exchange (LE), facilitating the support of Access Network (AN) solutions. This standard specifies an abstract test suite (ATS) using TTCN and provides a proforma for protocol implementation extra information for testing (PIXIT). The primary goal is to establish robust conformance tests that help ensure interoperability between access networks and local exchanges using the V5.2 interface, particularly for systems supporting up to N interfaces at 2048 kbit/s with concentration capability.

The guidelines, methodologies, and definitions outlined in SIST ETS 300 347-7:1997 play a crucial role in verifying protocol compliance and operational reliability in telecommunications infrastructures relying on the V5.2 interface. The data link layer focus ensures consistent and standardized communication for networks integrating PSTN and ISDN services.

Key Topics

• Test Suite Structure (TSS): Provides the organization and classification of tests, including the dynamic behaviors, state transitions, and test step procedures relevant to V5.2 protocol operations.
• Test Purposes (TP): Clarifies the intent of individual tests, targets specific protocol functions, and ensures comprehensive coverage of control and operational scenarios for the data link layer.
• Data Link Layer Testing: Focus on the LAPV5-DL (control protocol), LAPV5-EF (envelope function), and relevant mapping functions for both AN and LE environments.
• Configuration & Provisioning: Details the required test configurations for ISDN-BA, ISDN-PRA, and PSTN port support, along with guidance on provisioning for effective testing scenarios.
• Test Methodology: Based on ISO/IEC 9646 standards for open systems interconnection, ensuring internationally aligned test procedures.
• PIXIT Proforma: Defines additional information needs from implementers to support comprehensive interoperability testing.

Applications

Adhering to SIST ETS 300 347-7:1997 delivers clear benefits in telecommunication networks deploying digital local exchanges and access networks:

• Conformance Testing: Enables manufacturers and operators to validate that protocol implementations for V5.2 interfaces meet strict international and European standards.
• Interoperability Assurance: Critical for multi-vendor deployments, the standard ensures that access networks and local exchanges from different suppliers work seamlessly together.
• Network Upgrades and Integration: Facilitates smoother network expansions and technology upgrades by providing a reliable testing framework.
• Quality Assurance: Improves service reliability and performance for PSTN and ISDN communications over V5.2 interfaces.
• Compliance Documentation: Assists technical teams in generating and maintaining clear compliance and test records, supporting regulatory and procurement requirements.

1 Scope
This seventh part of ETS 300 347 contains the Test Suite Structure and Test Purposes (TSS&TP) for the
Data Link Layer (DLL) of the V5.2 Interface.
The objective of this ETS is to provide conformance tests giving a high probability of inter-operability of the
DLL of an Access Network (AN) and a Local Exchange (LE) infrastructure. This ETS covers only the
procedures described in ETS 300 347-1 [3] which are based upon ETS 300 125 [1].
ISO/IEC 9646-1 [5] and ISO/IEC 9646-2 [6] are used as the basis for the test methodology.
For test definitions of protocol functions which are tested in V5.2 the same way as in V5.1, only reference
is made to ETS 300 324-7 [2].
ETS 300 347-1 [3] defines the sublayers of the DLL, i.e. Link Access Protocol for V5 interface (LAPV5)
Data Link sublayer (LAPV5-DL), LAPV5 Envelope Function sublayer (LAPV5-EF) and the mapping
function (see ETS 300 347-1 [3], figure 6, which illustrates this approach). Regarding the conformance
testing, these sublayer functions are not tested separately. The test purposes defined in clause 5 cover
testing of the LAPV5-DL (control protocol only), LAPV5-EF and the mapping function. The AN frame relay
function is tested in co-operation with a generic test of an Integrated Services Digital Network (ISDN)
D-channel.
The limitation of the DLL test to the Control DL is based on the assumption that the Public Switched
Telephone Network (PSTN) DL, the Protection DL, the Link control DL and the Bearer Channel
Connection (BCC) DL implementations are identical with the Control DL implementation. This needs to be
declared by the Implementation Under Test (IUT) supplier. Otherwise, the test purposes defined for the
Control DL may be used for the other DLs as well.
