SAN JOSE, Calif. and NEUBIBERG, Germany, May 17, 2010 (GLOBE NEWSWIRE) -- DSP Group, Inc™. (Nasdaq:DSPG), a leading global provider of wireless chipset solutions for converged communications at home, and Lantiq, a leading company in next-generation access and home networking technologies, jointly announced the successful completion of interoperability testing based on the CAT-iq 2.0 (Cordless Advanced Technology: Internet and Quality) specification.

Recently adopted as an industry standard, CAT-iq 2.0 ( http://www.cat-iq.org ) is a key technology to enable advanced communications and infotainment applications driven by IP-based gateways in the digital home. The standard meets the requirement for widespread availability of fully interoperable home gateways, access points and cordless handsets to deliver the best user experience possible.

"Industry cooperation is essential for the success of the CAT-iq standard," said Brian Robertson, President of DSP Group. "We are pleased to collaborate with competing companies to ensure that third-party interoperability is not just a possibility but is actually achieved. The future of converged communications is about giving consumers more choices and flexibility and we are fully committed to continuous innovation to make this vision a reality."

The joint testing included interoperability between cordless handsets and residential gateways and demonstrated an excellent user experience of diverse telephony functions including phonebook management, synchronized call lists and multi-line support. DSP Group and Lantiq's silicon and software solutions are deployed in many IP telephony and gateway products, including xDSL, cable, xPON and office PBX, providing multi-line and multi-handset control, natural wideband voice and advanced data services.

"Interoperability is a significant milestone in bringing the CAT-iq 2.0 specification to market and is the key to the standard's success," said Ulrich Huewels, SVP and GM of Business Unit CPE of Lantiq. "Lantiq has an extensive background in interop testing with competitors through its carrier engagements in voice and DSL, and with CAT-iq, we continue to pursue this path to ensure the future success of industry's new standard. Lantiq reinforces its commitment through its investment in the technology by embedding CAT-iq in all of its residential xDSL and Ethernet-based gateway devices."
