DUA Signaling Tester
Test Harness & Test Suite for the Validation of DUA Implementations.
DUA Conformance Test Architecture
Overview
The DUA Signaling Tester is a test environment for the DUA signaling specification as defined by the IETF standards. It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against DUA 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 DUA interface library (API), which defines the DUA messages and parameters. The test harness includes a DUA 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 DUA Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.
Key Features
- Fully integrated, complete test environment for DUA
- ISO conformant test scenarios giving framework coverage of DUA
- Graphical development environment & libraries for creating new DUA tests
- Compatible with ACATS DUA Professional Test Suite (not included)
- Expandable for SIGTRAN, SIP, ISDN, ISUP-SIGTRAN interworking
- DUA Reference Test Object
VoIP Architecture
Description
The DUA Signaling Tester was designed to be a complete solution for DUA signaling test requirements. It has the key components:
- DUA Test Harness including codec & IP stack
- ACATS DUA Framework Test Suite
- DUA Interface Library
- DUA Protocol Analyzer
The DUA 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 DUA Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with the IETF IUA RFC 3057, RFC 4129 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 DUA Framework Test Suite includes test scenarios for the validation of terminal equipment by simulating the controlled interaction with other DUA 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 DUA test object. They are also an excellent basis for customization and enhancement according to specific needs.
An upgrade is available for the ACATS DUA Professional Test Suite, which offers extensive coverage of the DUA signaling test requirements.
DUA 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.
