MGCP Signaling Tester

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

MGCP Conformance Test Architecture

Overview

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

Key Features

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

Description

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

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

The MGCP 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 MGCP Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with IETF standard RFC 3435.  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 MGCP Framework Test Suite includes test scenarios for the validation of terminal equipment by simulating the controlled interaction with other MGCP 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 MGCP test object. They are also an excellent basis for customization and enhancement according to specific needs.

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

MGCP 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.
