An important profitability factor for service providers is the ability to cost-effectively scale to higher network capacities while continuing to expand next-generation IP/MPLS service offerings. The Cisco 2-Port OC-192 POS Line Card, in conjunction with 40 Gbps/slot Cisco 12800 Routers, scales the Cisco 12000 Series Router to 50Mpps per slot forwarding capacity. It maximizes return on investment in the Cisco 12000 Series by providing full interoperability with all existing Cisco 12000 Series line cards.The Cisco 2-Port OC-192 POS Line Card features a dedicated Layer 3 forwarding engine that offers a comprehensive IP/MPLS feature set, including advanced quality of service (QoS), accounting (sampled NetFlow), security and traffic control, and committed access rate (CAR) - all at 50Mpps. Enabling service providers to keep pace with next-generation service expansion, the line card supports more than one million prefixes, up to 256, 000 multicast groups, and more than 32, 000 lines of access control lists (ACLs), both ingress and egress, at wire speed.For maximum flexibility, the Cisco 2-Port OC-192 POS Line Card is equipped with third-generation optics for improved component integration, power consumption, and cost reduction. It is fully interoperable with standard OC-192c and STM-64c optical interfaces. Available optics include short-reach (SR), intermediate-reach (IR), long reach (LR), and very short reach (VSR) optics.
