8 x T3/E3
- Description:
- The 1000 Series 8-Port Unchannelized E3/T3 Line Card provides flexibility, scalability, and an enhanced price-to-performance ratio in the E3/T3 aggregation market. Targeted primarily at Internet service providers (ISPs) for situations in which fiber interfaces are unavailable or prohibitively expensive, the Cisco 10000 Series Unchannelized E3/T3 Line Card supports eight E3/T3 ports (Layer 2 connectivity). Layer 3 services are supported by the Cisco 10000 Series advanced Cisco Performance Routing Engine (PRE). By taking advantage of the advanced PRE architecture, ISPs will enjoy the necessary processing performance to enable the advanced IP services that users demand.
