Nokia Siemens Networks claims 825 Mbps via Phantom DSL is world record
OCTOBER 25, 2010 -- Phantom DSL has struck again. Nokia Siemens Networks says it has used the technology to transmit data at 825 Mbps over 400 m of bonded copper lines and 750 Mbps over 500 m.Back in April, Alcatel-Lucent Bell Labs announced it had achieved 300 Mbps over 400 m using what it called “Phantom Mode.egardless of what you call it, the technology involves creation of a virtual -- or “phantom” -- channel to supplement the two physical wires that are the standard configuration for copper transmission lines.Phantom DSL promises a bandwidth increase of 50-75% over existing bonded copper lines, Nokia Siemens Networks says. Such capabilities could prolong the life of copper networks and delay a wholesale switch to fiber to the home (FTTH).Nokia Siemens Networks says its implementation of Phantom DSL will become an integral part of the company’s hiX 562x/3x DSLAM products.

Ikanos NodeScale Vectoring improves DSL performance
OCTOBER 25, 2010 -- Ikanos Communications Inc. (NASDAQ: IKAN) has unveiled NodeScale Vectoring. By countering the effects of such impairments as cross talk, NodeScale Vectoring can enable 100-Mbps performance via DSL, Ikanos asserts.One of the challenges in deploying very high-speed Internet access over copper infrastructure is the degradation that occurs as a result of crosstalk between coincident copper-wire pairs. Each wire can often and intermittently interfere with neighboring wires, thereby introducing noise, limiting line quality, and reducing VDSL performance. Other impediments including AM radio signals, power lines, lightning, and other atmospheric elements inject even more noise into the copper network.Ikanos' NodeScale Vectoring technology is designed to analyze the crosstalk and interference environment in real time and create a unique set of compensation signals that effectively eliminates both. Ikanos says that NodeScale Vectoring cancels noise across an entire network node from 192 to 384 ports or more using a combination of patent-pending algorithms and compression and coding techniques.The complete system includes NodeScale Vectoring compatible line cards, Vector Computation Engines, and G.vector-ready customer premises equipment. The system can be deployed to increase the performance of existing VDSL nodes, as part of ADSL network upgrades, and in copper plants that previously served only plain old telephone service (POTS), Ikanos says. As the same Ikanos chipset supports vectored and non-vectored deployments, upgrades can occur on a line-by-line basis."Vectoring across the entire node is the only practical approach for realizing the true benefits that G.vector can bring to a VDSL deployment. It is critical to have centralized control and visibility on all possible sources of crosstalk that can degrade the performance in a cable or binder. Approaches which cannot address all sources of crosstalk in a node, such as line card-level vectoring, will prove to have minimal measurable benefits in real world deployments," said (Franz) Liu Feng, marketing director, Fixed Network Product Line at ZTE. "NodeScale Vectoring will have a dramatic impact on service provider networks around the world, allowing carriers to deliver the performance their customers demand without having to incur the costs of overhauling their entire network."

Actiontec launches FTTH-compatible pair-bonded VDSL2 home routers
OCTOBER 25, 2010 -- Actiontec Electronics has introduced two new pair-bonded VDSL2 routers to its portfolio of IPTV residential gateways. The V2000H and Q2000 routers have been built to support high-bandwidth triple-play services, including HD video/IPTV and voice over IP.Both IPTV routers support pair-bonded and single-line VDSL2 and single-line ADSL2+. The routers also feature an "Auto Fallback to ADSL 2+/2" function that lets providers deploy the same device on older networks. In addition to DSL support, the V2000H also is equipped with a 10/100/1000 Gigabit Ethernet WAN port for fiber to the home (FTTH) applications.The multiple architecture support enables carriers and broadband providers to use the same CPE across all their deployment regions, including FTTH, fiber to the node (FTTN), and fiber to the premises (FTTP) architectures. "Universal flexibility is a key theme in our CPE strategy," said Brian Henrichs, chief business development officer at Actiontec Electronics. "We believe in building products that can be seamlessly used across different territories and different network topologies, today and tomorrow. Our collaboration with leading service providers confirms that this approach yields significant operational savings."Both routers feature echnology o upport triple play applications, including:high-speed etwork interfaces;robust memory architecture;onded VDSL technology for improved bit rates and reach.Both routers also feature an enhanced wireless N radio and a built-in Gigabit Ethernet switch for speeds up to 1000 Mbps, says Actiontec. In addition, the V2000H supports the latest HomePNA (HPNA) technology.Optional support for Java Virtual Machine and Java Runtime Software enable the V2000H and Q2000 to host a number of Java applications, such as home automation and enhanced security. Applications can be instantly enabled as soon as they're ordered (similar to a mobile app experience), rather than requiring a lengthy full-scale firmware update or other cumbersome process, Actiontec asserts.The V2000H and Q2000 also support TR-069 remote management capabilities to enable technical support staff to remotely troubleshoot customer problems without a home visit.
