The modular design of the Cisco 12000 Series routers helps customers generate new revenue, while reducing capital and operating expenses. The ability to scale the Cisco 12000 Series routers from 2.5-Gbps to n x 10-Gbps capacity per slot helps enable carrier-class IP/MPLS networks, while protecting investments in chassis and line cards.

An important feature of the Cisco 12000 Series routers is the Cisco I-Flex design. This is a portfolio of shared port adapters (SPAs) and SPA interface processors (SIPs) that prioritize voice, video, and data services so users can meet their customers' varied service needs and stringent service-level agreements.

They also feature advanced silicon and software technologies for high standards of routing performance and QoS, comprehensive high-availability support to help avoid planned and unplanned network downtime, integrated core and edge feature set which supports a wide range of business and consumer services, and a fully upgradable modular switch fabric and Cisco IOS XR Software upgrade ability to protect investments and lessen entire cost of ownership.
