12000 Series of packet over SONET/SDH (POS) line cards deliver state-of-the-art technology to cost-effectively
scale carrier-class IP/Multiprotocol Label Switching (MPLS) packet infrastructures to meet the needs of service providers
around the world (Figures 1 and 2). The POS interfaces deliver high-performance, powerful features and a full range of
interface types, speeds, and connectors, enabling deployment of high-speed core, peering, and edge applications. The POS
line cards provide the ideal solution to meet and exceed the ever-growing demands for higher capacity and service
availability.
CISCO ISE POS INTERFACES—DELIVERING ROBUST HIGH-SPEED EDGE FUNCTIONS
Service providers face the challenge of meeting customer demand by building scalable, feature-rich networks that can deliver value-added services
such as private IP connectivity; integrated data, voice, and video services; and tiered service offerings—at all interface rates without compromising
density or line-rate performance. The Cisco IP Services Engine (ISE) line cards provide the same powerful feature set as the standard POS line cards
and also accommodate service provider requirements by providing an extensive set of service-enabling edge features at line rate such as packet
classification, congestion avoidance, and low-latency queuing (LLQ).
