Vitesse 以太网交换机为无线回传和电信级接入应用提供网络时序解决方案

Equally important is Caracal’s integrated support for Ethernet Operations, Administration and Maintenance (OAM), including full hardware-based Continuity Check Messages. This support provides protection switching in less than 50 ms – the same rapid-failover rate used in today’s wireline SONET/SDH standards. These features, combined with Vitesse’s comprehensive Carrier Ethernet software solutions, uniquely enable a smooth migration to packet networks from currently deployed SONET/SDH networks.

Offering the highest level of integration in the industry, the Caracal devices are fully featured Carrier Ethernet switches with integrated Cu PHYs and MIPS processor. The integrated dual media PHY enables a simple hardware design with flexible combination of copper and optical ports. The MIPS processor can run customer management and control software while delivering a warm restart capability that allows network providers to reload software and reboot the switch without interrupting customer service.

Unprecedented Low Power, Energy Efficiency

The new devices embed Vitesse’s EcoEthernet™ 2.0 green technology, exceeding the IEEE 802.3az specifications requirements while delivering unprecedented energy efficiency. Power dissipation of 365 mW/port for 1000BASE-T copper and <200 mW/port is achieved when connected to Fast Ethernet devices, making Caracal switches the most fully featured, low-power Carrier Ethernet solution for mobile backhaul and access applications.

The VSC7428 (Caracal-1) provides up to 11 SGMII ports and eight Gigabit Cu PHYs, while the VSC7429 (Caracal-2) provides 26-ports with combinations of 12 copper PHYs, 12 SGMII, and three QSMII ports. Both devices have 10/100/1000 Mbps ports, with two ports supporting 10/100/1000 and 2.5 Gbps. All SGMII ports support 100 BASE-FX and 1000 BASE-X SerDes for direct attach optical connections. Overall, Caracal switches offer rich carrier features including 1588v2 timing and a high level of integration and support for redundant network and ring configurations, making Vitesse’s latest offering uniquely suited for Carrier access applications such as base station interconnect, mobile backhaul and PON MDU.

Samples of the VSC7428 and VSC7429 will be generally available in the third quarter of calendar 2010. More information about the Caracal devices can be found at:
