XAVi Selects Ikanos' Vx180 Gateway Processor

XAVi Technologies, a supplier of broadband residential gateways and customer premise equipment, has selected the Ikanos Fusiv Vx180 high-performance gateway processor for its VDSL2/ADSL2+ triple play residential gateways. The XAVi residential gateways will be sold globally, with a primary focus on the North American and European markets.

Ikanos Communications' Fusiv Vx180 is a low power single-chip multi-mode VDSL2/ADSL2+ gateway processor designed to enable service providers to launch next generation services. The Vx180 provides 2.7 GHz of processing power with integrated voice over Internet protocol (VoIP) processing while supporting best-in-class quality of service (QoS) for triple play experiences. The Vx180 features Ikanos' unique Accelerator Processor architecture, making it capable of achieving wirespeed packet processing performance across all LAN and WAN interfaces. Additionally it easily integrates with home networking technologies, such as MoCA, Home PNA, HomePlug and 802.11n.

Ikanos' Vx180 also supports features such as Ikanos' Rapid Rate Adaptation (RRA) and Seamless Rate Adaptation (SRA) technologies, thereby enabling the development of a high performance, integrated residential gateway platform for multi-play applications.

  • Ikanos' Rapid Rate Adaptation (RRA) technology is designed to minimize noise-induced service interruptions over DSL connections. Noise over a broadband line due to sudden power surges or other sources can potentially cause dropped connections and interruptions of service. For IPTV viewers, even a momentary drop in the connection leads to retraining of the broadband line and a subsequent re-establishment of the IP connection -- a process than can take half of a minute. In the mean time, the TV program that is being watched and any VoIP sessions underway, are suddenly dropped. RRA minimizes such link drops by rapidly and dynamically adapting data rates to accommodate the additional noise without dropping the connection, thus improving service availability and the user experience.
