ISDN PRI L2 Signaling Tester

Test Harness & Test Suite for the Validation of ISDN PRI L2 Implementations.

ISDN PRI L2 Conformance Test Architecture

Overview

The ISDN PRI L2 Signaling Tester is a test environment for the ISDN PRI L2 signaling specification as defined by the ITU-T standards. It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against ISDN PRI L2 test objects in a controlled & deterministic manner.

The SAFIRE graphical editor allows new scenarios to be created or existing scenarios to be modified using the ISDN PRI L2 interface library (API), which defines the ISDN PRI L2 messages and parameters. The test harness includes an ISDN PRI L2 protocol analyzer for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.

The ISDN PRI L2 Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.

Key Features

• Fully integrated, complete test environment for ISDN PRI L2
• ISO conformant test scenarios giving framework coverage of ISDN PRI L2
• Graphical development environment & libraries for creating new ISDN PRI L2 tests
• Compatible with ACATS ISDN PRI L2 Professional Test Suite (not included)
• Expandable for ISDN PRI L3, V5 L2 & V5 L3
• ISDN PRI L2 Reference Test Object

Fixed Access Network Architecture

Description

The ISDN PRI L2 Signaling Tester was designed to be a complete solution for ISDN PRI L2 signaling test requirements.  It has the key components:

• ISDN PRI L2 Test Harness including codec & ISDN stack
• ACATS ISDN PRI L2 Framework Test Suite
• ISDN PRI L2 Interface Library
• ISDN PRI L2 Protocol Analyzer

The ISDN PRI L2 test harness uses the powerful SAFIRE environment to provide advanced features like

• Graphical editing (flow diagram representation)
• Automated execution of test campaigns
• Slow motion replay with synchronized trace & breakpoints
• Test reports with statistics (also HTML)
• Real-time, high performance protocol analysis

Using the ISDN PRI L2 Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with ITU-T standard Q.921.  It is suitable for manufacturers, network operators and service providers to address all stages of the development cycle, regression testing through to type approval, acceptance testing & certification (note: requirements may be country/organization specific).

The ACATS ISDN PRI L2 Framework Test Suite includes test scenarios for the validation of Fixed Access network components by simulating the controlled interaction with other ISDN PRI L2 entities such as

• Access Network (AN)
• Network Termination (NT)

SAFIRE Editor Sample

The framework test suite contains a selection of important scenarios, which can be used to confirm the basic functionality of a ISDN PRI L2 test object.  They are also an excellent basis for customization and enhancement according to specific needs.

An upgrade is available for the ACATS ISDN PRI L2 Professional Test Suite, which offers extensive coverage of the ISDN PRI L2 signaling test requirements.

ISDN PRI L2 Reference Test Object

For reference a virtual test harness is included, that allows test scenarios to be run off-line against a software-only test object under controlled conditions.  The test harness uses a software bus to replace the physical connection and an accurate software model as the test object.  Normally fully automated execution of tests is possible, but in some specific cases the test object allows/requires user interaction during the tests.
