ARRS Arris International Plc - Ordinary Shares

Microtune's MicroTuner MT2050 Single-Chip Tuner, Implemented in ARRIS' Advanced Telephony Modems, Enables High-Speed Data and Toll-Quality Voice Services Microtune(R), Inc. (Nasdaq:TUNE) announced today that global communications technology leader ARRIS (Nasdaq:ARRS) has implemented the MicroTuner(TM) MT2050 single-chip tuner as the core radio frequency (RF) component in ARRIS' DOCSIS(R)- and PacketCable(R)-certified Touchstone(TM) Telephony Modems. In production today, ARRIS' TM402 series of telephony modems leverages the miniature size, low power and cost efficiencies of Microtune's RF silicon technology to deliver high-speed data access and carrier-grade Voice over IP (VoIP) phone service. Its Touchstone modems permit cable operators to maximize revenue potential by providing quality, reliable and economical multimedia service options to cable subscribers. Microtune, inventor of and a market leader in single-chip TV tuner technology, develops RF silicon and systems solutions for consumer electronics and broadband communications. ARRIS is a market leader in Certified- and Qualified- cable solutions for cable operators worldwide, and according to Kinetic Strategies' June 2005 Cable Digital News report, is the number one supplier of VoIP telephony modems in the world. "ARRIS has played a major role in VoIP telephony, helping worldwide cable operators deliver the triple play of video, voice and data to their subscribers. We are proud to be a part of ARRIS' broadband cable strategy," said Albert Taddiken, Chief Operating Officer of Microtune. "To deliver the most advanced and cost-effective solution to its customers, ARRIS chose our MT2050 silicon tuner for its advanced RF enabling technology. The on-board tuner implementation improved price/performance and reliability, while offering a much smaller footprint for thin, sleek telephony modem designs. ARRIS' successful transition to the MT2050 demonstrates the viability of deploying our silicon tuners in low-power, battery-backed cable applications that must also meet stringent CableLabs(R) RF performance requirements." "Microtune's MT2050 tuner enables us to meet our VoIP business objective with the quality, performance and low-power demanded of DOCSIS and Packet Cable standards," added Bruce McClelland, VP Engineering, ARRIS Broadband. "Microtune provides a cost-efficient, stable RF technology that assists us in delivering increased throughput, speed, capacity and reliability in our market-leading telephony modems."
