H.323 Signaling Tester

Test Harness & Test Suite for the Validation of H.323 Implementations.

H.323 Conformance Test Architecture

Overview

The H.323 Signaling Tester is a test environment for the H.323 signaling specification as defined by the ETSI standards. It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against H.323 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 H.323 interface library (API), which defines the H.323 messages and parameters. The test harness includes a H.323 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 H.323 Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.

Key Features

• Fully integrated, complete test environment for H.323
• ISO conformant test scenarios giving framework coverage of H.323
• Graphical development environment & libraries for creating new H.323 tests
• Compatible with ACATS H.323 Professional Test Suite (not included)
• Expandable for SIGTRAN, SIP, ISDN, ISUP-H.323 interworking
• H.323 Reference Test Object

Description

The H.323 Signaling Tester was designed to be a complete solution for H.323 signaling test requirements.  It has the key components:

• H.323 Test Harness including codec & IP stack
• ACATS H.323 Framework Test Suite
• H.323 Interface Library
• H.323 Protocol Analyzer

The H.323 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 H.323 Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with the published ETSI TS 101-804-2 2002/10 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 H.323 Framework Test Suite includes test scenarios for the validation of terminal equipment by simulating the controlled interaction with other H.323 entities such as

• Terminal
• Gateway
• Gatekeeper

SAFIRE Editor Sample

The framework test suite contains a selection of important scenarios, which can be used to confirm the basic functionality of a H.323 test object. They are also an excellent basis for customization and enhancement according to specific needs.

An upgrade is available for the ACATS H.323 Professional Test Suite, which offers extensive coverage of the H.323 signaling test requirements.

H.323 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.
