The Cisco 12000 Series 4-Port OC-12c/STM-4c POS/SDH ISE Line Card features the Cisco 12000 Series ISE technology—a unique, edge-optimized, programmable adaptive network processor that combines the hardware performance of application-specific integrated circuits (ASICs) with the flexibility of software. Together, the 12000 Series and ISE technology enable a broad range of edge services and accommodate future customer requirements with simple software upgrades instead of costly hardware replacements.
Combined, the Cisco 12000 Series and ISE technology uniquely offer the advantages of a distributed architecture to 10G-enable the high-speed service provider edge by delivering linear performance scalability, a complete range of chassis form-factors, application-optimized line cards, and 10 Gbps uplinks. It offers the industry's only per-customer, guaranteed priority packet delivery for the edge by providing thousands of queues that can be dynamically assigned per port, unlimited input and output filters per port, and the most comprehensive set of quality-of-service (QoS) features available today, including packet classification, congestion avoidance, and low-latency queuing (LLQ).
