Munich, Germany – March 22, 2006 - National Technical Systems, Inc. (Nasdaq: NTSC) (NTS), a leading provider of quality and conformance testing and managed services, announces that it has completed NEBS certification testing for the 1460 Session Controller of Newport Networks, at its European subsidiary, NTS Europe GmbH, in Munich, Germany. Newport Networks Ltd. (London Stock Exchange: NNG) is the innovative developer of award winning, carrier-class session border controllers for the Voice over IP (VoIP) and Multimedia over IP (MoIP) markets.

The demanding Network Equipment Building System certification, also known by its acronym NEBS, is the most common set of safety, spatial and environmental design guidelines applied to telecommunications equipment in the United States. NEBS is why telephones work after the most trying calamities such as an earthquake, thunderstorm or fire.

“Our customers appreciate the fact that there is a full service ITL certified NEBS testing alternative to the United States, right in the heart of Europe,” notes Deniz Ezgi, Technical Account Manager. “Many European OEMs feel at a geographic disadvantage when they are confronted with the complexities of North American compliance regulations. NTS can locally contribute to their expertise and help them erase that disadvantage.  

“We have been very pleased with the service from NTS,” commented Mike Wilkinson, Vice President of Marketing at Newport Networks. “The Newport 1460 is the industry’s premier high capacity session border controller and ensuring strict NEBS compliance is a critical requirement for our American business,” he added.
