Empirix Broadens Support for IMS Device Emulation and Interoperability Testing in Award-Winning Hammer DEX.

STOCKHOLM, Sweden -- Hammer DEX enables network equipment manufacturers and service providers to accelerate testing cycles, get products and services to market faster

Empirix(R) Inc., which helps organizations adopt complex communications solutions with confidence, will preview the latest version of its new device emulation platform, Hammer Device Emulation of X (DEX) 2.0, at VON Europe this week. Hammer DEX is currently in use by several leading Network Equipment Manufacturers (NEMs) for NGN and IMS testing.

Hammer DEX 2.0 adds support for SIP registration testing and gateway testing with H.248 and SIGTRAN-IUA. It also provides even broader emulation and testing support for a wide range of IMS functions, including: CSCFs, MRFC, MGCF, BGCF, MGF, IBCF and I-BGF. Hammer DEX now also supports NGN devices including MGC emulation for Residential Gateways. In addition, Empirix will add support for DIAMETER to Hammer DEX this summer, allowing it to emulate and test Application Servers, SCIM functions, Convergence functions (CCCF), HSS, SLF and Charging functions.

Hammer DEX allows NEMs and service providers to emulate NGN infrastructure devices and IMS functions to enable a more comprehensive array of testing for verifying devices and networks, including interoperability testing. Hammer DEX also enables users to emulate products from other vendors, alleviating many of the time and cost constraints of obtaining these products.

"VoIP device manufacturers and service providers are struggling with how to certify their products and services for multi-service networks," said Olga Yashkova, Research Analyst at Global Growth Consulting firm Frost & Sullivan. "Device emulation is useful not only for testing the VoIP devices and services being rolled out today, but for the IMS architectures being rolled out in the future. We expect to see a lot more of this type of testing going forward."

According to Duane Sword, Vice President of Product Management and Marketing at Empirix, four main factors are driving the popularity of Hammer DEX:

--Cost and time effectiveness to emulate IMS devices (one Hammer DEX can emulate up to four IMS functions simultaneously);

--Out-of-box ability to span both positive and negative test scenarios for SIP and other major IMS control protocols;

--Growing awareness through trial and error of the importance of interoperability testing; and

--Global movement toward IMS by wireless, wireline and cable-service providers.

"We knew from our many years in VoIP, and now IMS, testing that there was a significant market need for better device emulation - a need we set out to meet with Hammer DEX," said Sword. "Market reception to Hammer DEX has been nothing short of outstanding - we are very excited and proud to be making such a significant impact on the industry."

Hammer DEX complements Empirix's Hammer portfolio of end-point emulation, feature, load testing, analysis, and post-deployment monitoring solutions allowing for testing throughout the full network lifecycle, from product development to post-network deployment.
