DATA SHEET

Test engineers are facing numerous challenges today: shorter test cycles, smaller teams, and more complex testing scenarios. Automation is often acknowledged as a possible solution, but has traditionally required extensive training and expertise, discouraging engineers who are already overworked and time-constrained.

Ixia’s Test Composer automation framework provides the answer: test engineers can finally realize the productivity benefits of automation without wasting time building scripts for their test tools.

Test Composer allows you to build and execute test suites with no knowledge of the MGTS programming interface. Its point-and-click scripting capability is easy to learn, reduces the time required to automate your test bed, and enables easy scheduling of overnight test runs. Test Composer configures your device(s) under test (DUT), as well as your MGTS test system, and collects results from all test components to determine whether the test passed or failed.

DATA SHEET

Test Composer offers test engineers more control over the MGTS application than any other automation tool on the market. The commands offer actions that allow you to download the test, start the test and check the status of the test. The Data Collection commands provide visibility at different levels from the high-level pass/fail status of the different state machines to the low-level EMR and Traffic reports. Test Composer validation steps use these collected statistics to check the results for test pass or failure.

Constructing and debugging tests has never been easier. The tests developed in the MGTS interface are used as the starting point for the automation. This shortens development time for new tests and allows the user to experiment with different scenarios before making formal changes to the test.

Test Composer & MGTS work together to accelerate test development

Even if full regression test automation isn’t the ultimate goal, Test Composer can also accelerate the process of manual testing. By constructing test sequences that automate DUT configuration as well as MGTS configuration, manual test engineers can quickly move past test setup into active testing.

Once tests have been constructed in Test Composer, they are easily managed and scheduled using Test Conductor, Ixia’s end-to-end automation solution.=

Test Conductor is easy to use and highly scalable. Test Conductor helps test engineering teams create, organize and catalog their tests and regression suites, scheduling tests to run unattended or on-demand.

Ixia MGTS SS7 Solution



MGTS® Signaling System 7 (SS7) Solution

The convergence of voice, data and video networks presents the telecom industry with many exciting challenges. In response to those challenges, telecommunications equipment manufacturers and service providers are competing fiercely to be the first to bring new products to market. To assure the quality, performance and interoperability of those products, Ixia offers the revolutionary Message Generator Traffic Simulator (MGTS). The MGTS® product line addresses diagnostic needs with easy-to-use, flexible and automated test solutions.

The MGTS product line spans wireline and wireless technologies and is based on high-performance platforms, the MGTS p250, p400 and m500. High level applications provide sophisticated diagnostic capabilities for specific technologies: SS7, including SS7 over asynchronous transfer mode (ATM); general packet radio services (GPRS); universal mobile telephone system (UMTS); and Internet protocol (IP).

MGTS SS7 The MGTS SS7 is an advanced diagnostic and test platform for research and development labs and service providers. Its functions include integration and system testing as well as field deployment. With its combination of ready-to-use applications, graphically programmable applications, and extensive protocol support, the MGTS diagnoses and tests complex signaling protocols. The MGTS SS7 can be used in all phases of development, including the following:

• As a functional test tool during the protocol development phase of signaling products

• As a simulator of lower protocol layers


• As a high-load diagnostic tool for network integrity and peak performance testing



The state machine editor enables users to visually examine the logic behind test cases

Functions The MGTS SS7 simulates network elements to conduct complete load capacity testing and protocol analysis, including SS7 over ATM lower layers. Features include:

• Load capacity validation and confirmation

• Signal transfer point (STP) performance testing

• Signal control point (SCP) performance testing

• Regression testing

• Protocol analysis of SS7 traffic


• Protocol analysis of high-speed B and D links across STPs




STP Emulation Package The package simulates STPs, including high-speed link STPs, which may be an integral step in test bed setup. Users can configure flexible test beds, reducing the cost of deploying actual STPs in a lab environment.

SCP Simulation Package With the use of the protocol adaptable state machine (PASM™), the MGTS creates SS7 messag structures, contents and sequences, and signaling test cases against an SCP under test. The SCP may be advanced intelligent network (AIN), local number portability (LNP), interim standard 41 (IS41), or global system for mobile communications (GSM)/home locator register (HLR).

Network Performance Load Simulation Package (NPLT) The package generates and validates heavy traffic load across STPs under test to assess STP performance. The MGTS running NPLT can generate loads from one to 32 links, per simulated device.

NPLT Traffic Reports NPLT traffic reports indicate the number of message signal units (MSUs) transmitted and received. NPLT Traffic Reports includes delay analysis. The delay analysis report segments the cross-STP delay into “delay buckets,” providing distribution based on the MSU generated and received during a test run.

Protocol Adaptable State Machine (PASM™) The MGTS utilizes PASM to enable the user to construct custom test cases graphically in a non programmable environment. PASM is protocol-independent, supporting standard and proprietary protocols as well as variations from different countries.
