Cisco 12000 Series Three-Port Gigabit Ethernet Line Card

Cisco offers the Cisco 12000 Series Three-Port Gigabit Ethernet Line Card (3-Port GbE) to address the needs for interconnecting devices within points of presence (POPs) at gigabit rates. The Cisco 3-Port GbE Line Card is the second Ethernet-based product for the Cisco 12000 Series, providing a cost-effective, high-bandwidth solution. This compelling solution is sought by Internet service providers (ISPs) with large Web hosting equipment such as servers, caches, edge routers, Gigabit Ethernet switches, and so on, who are looking for cost-effective links between their Cisco 12000 Series Routers and other network equipment.
