IUA Signaling Tester

Test Harness & Test Suite for the Validation of IUA Implementations.

IUA Conformance Test Architecture

Overview

The IUA Signaling Tester is a test environment for the IUA signaling specification as defined by the IETF standards. It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against IUA 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 IUA interface library (API), which defines the IUA messages and parameters. The test harness includes a IUA 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 IUA Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.

Key Features

• Fully integrated, complete test environment for IUA
• ISO conformant test scenarios giving framework coverage of IUA
• Graphical development environment & libraries for creating new IUA tests
• Compatible with ACATS IUA Professional Test Suite (not included)
• Expandable for SIGTRAN, SIP, ISDN, ISUP-SIGTRAN interworking
• IUA Reference Test Object

Description

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

• IUA Test Harness including codec & IP stack
• ACATS IUA Framework Test Suite
• IUA Interface Library
• IUA Protocol Analyzer

The IUA 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 IUA Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with the IETF IUA RFC 3057 standard.  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 IUA Framework Test Suite includes test scenarios for the validation of terminal equipment by simulating the controlled interaction with other IUA entities such as

• Media-Gateway (MG)
• Media-Gateway Controller (MGC)

SAFIRE Editor Sample

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

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

IUA 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.
