ARRIS, Xtend Networks Achieve Full DOCSIS(R) 2.0 Operation Over HFC Extended Spectrum Network ATLANTA and SUWANEE, Ga., Jan. 31 /PRNewswire-FirstCall/ -- Xtend Networks(TM), a Vyyo(R) (NASDAQ:VYYO) company providing up to 3Ghz of bandwidth over hybrid-fiber coax (HFC) plant for the cable TV industry, and ARRIS (NASDAQ:ARRS) today announced the ability to offer dedicated high-bandwidth spectrum to commercial customers using standard DOCSIS(R) products. In the tests conducted at ARRIS' Suwanee laboratories, engineers used off-the-shelf Xtend and ARRIS DOCSIS(R) products under a normal testing environment. Reliable operation and high performance were achieved at 256 QAM modulation downstream and 64 QAM SCDMA modulation upstream. These tests illustrate cable operators' ability to deliver a dedicated high-speed data service to commercial customers utilizing existing HFC plant and standard off-the-shelf DOCSIS products. The tests were conducted using an ARRIS C3(TM) CMTS and Touchstone(TM) CM450 cable modem, in conjunction with Xtend Networks' XHUB node product, its XFR trunk amplifier, its XTB CPE device and passive elements. "As bandwidth needs increase and competitors increase fiber builds, cable system operators are asking vendors to maximize the installed HFC infrastructure," said Wade Carter, ARRIS Director of Engineering. "By working with Xtend, we have an opportunity to create an end-to-end solution that enables operators to deliver unprecedented dedicated high-speed data services to their marketplace." "Commercial customers are eager to explore alternatives to incumbent telecom providers for the delivery of high bandwidth services," said Brent Levetan, Vice President, Business Development for Xtend Networks. "Our work with ARRIS will enable both of our companies to take leading roles in the creation of the infrastructure capacity that the industry needs to take market leadership in those new market areas." Xtend's products are based on the ability of advanced application technology and Block Division Multiplexing to increase the available spectrum of the existing cable TV network while providing high-speed symmetrical services to subscribers. Xtend technology is compatible with the existing head-end and CPE devices, including DOCSIS(R), analog and digital TV transmission, and telephony.
