Empirix Enhances VoIP Testing Tool

BY JOHANNE TORRES


VoIP testing systems provider Empirix (news - alert) today announced it enhanced the company’s Hammer NXT VoIP ( define - news - alert) and TDM performance testing system.  With the enhancements, this testing tool is said to offer unmatched load scalability and to dramatically reduce the costs associated with high-density load testing and performance verification of VoIP and PSTN network elements and networks. 


Empirix developed Hammer NXT systems for network equipment manufacturers and service provider labs to enable the creation of load testing environments that scale to more than 50,000 endpoints (signaling and media).  The NXT has been enhanced to incorporate the company’s patent-pending IP.DSP technology—which provides high density testing capacity and media analysis while reducing test system per port costs by up to a factor of 10 times.

"Load testing is critical for network equipment manufacturers and service providers seeking to bring services to market faster and is especially important today as the VoIP market moves from the emerging stage to the deployment stage.  With these enhancements to the Hammer NXT, Empirix has boosted the system’s cost-effectiveness, performance and flexibility, significantly increasing its value proposition to customers,” said Jessy Cavazos, Industry Analyst and Sector Leader of the Communications Test & Measurement Group at Frost & Sullivan. “Empirix is a leader in the world VoIP test equipment market.  This announcement is key to the company's R&D test equipment portfolio and demonstrates its commitment to the lab, even as the company leverages its market strength into VoIP monitoring."

The system can detect and analyze the content of each media stream generated (up to 24K) at full Ethernet line rates, including detection of tones, DTMF, voice prompts, silences and energy, allowing users to stress and verify media functionality under high-density conditions.  A wide range of codecs are supported, as well as unique IP and MAC address emulation.

The new NXT shares a common signaling engine and architecture with the Hammer FX-IP functional test system. Customized protocol and signaling configurations can be ported between the two platforms.  With the Hammer Mega-Controller in place, engineers can create a single, integrated test environment that speeds feature and load testing for VoIP network equipment, such as media gateways, soft switches, media servers and session border controllers..
