Details
The Cisco® Interface Flexibility (I-Flex) design combines shared port adapters (SPAs) and SPA interface processors (SIPs) to help enable service prioritization for voice, video, and data services. Enterprise and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The extensible Cisco I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. Cisco I-Flex enhances speed-to-service revenue and provides a rich set of quality of service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications for the Cisco 1-, 2-, and 4-Port OC-48c/STM-16c Packet over SONET/SDH (POS) and Resilient Packet Ring (RPR) Shared Port Adapter (Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS/RPR SPA; refer to Figure 1).

Key Features and Benefits
• Industry-leading modular, flexible, intelligent interface processors
– Unmatched flexibility, allowing a combination of interface types on the same interface processor for consistent services, independent of access technology.
– Pioneering programmable interface processors that provide flexibility for the service diversity required in next-generation networks.
– Innovative design that provides intelligent delivery of services without compromising on performance.
• Increased speed-to-service revenue
– The scalable, programmable Cisco architecture extended to 2.5 Gbps dramatically improves customer density, increasing potential revenue per platform.
– Interface breadth (copper, channelized, POS, ATM, and Ethernet) on a modular interface processor allows service providers to more quickly roll out new services, ensuring all customers, large and small, receive consistent, secure, and guaranteed services.
– High-density SFP interfaces are featured for high-port-count applications with reach flexibility. Future optical technology improvements can be adopted using existing SPAs.
• Significant investment protection
– Improved slot economics and increased density reduce capital expenditures (CapEx).
– The ability to easily add new interfaces as they are needed facilitates a "pay-as-you-grow" business model while still offering a high-density solution.
– SPAs are shared across multiple platforms, and can be easily moved from one to another, providing consistent feature support, accelerated product delivery, and a significant reduction in operating expenses (OpEx) through common sparing as service needs change.

Note: The OC48 SPAs support tri-mode operation as POS, DPT or 802.17 RPR protocol interfaces. POS mode is provided by all platforms on which the SPA is supported. Additional software support is needed to enable operation in DPT or 802.17 RPR modes. The table above shows the earliest release of support for each SPA on the platform and does not show detail with respect to the SIPs on which the SPA is supported. This datasheet will be updated as support is added, but customers are encouraged to check with their Cisco Representative to get the most up-to-date information on SIP/SPA compatibility.
