e, video, and data services. Enterprise and service provider customers can take advantage SPA-1XOC48POS RPR思科模块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 throSPA-1XOC48POS RPR思科模块ugh 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 POSSPA-1XOC48POS RPR思科模块/RPR SPA; refer to Figure 1).
Product Overview
SPA-1XOC48POS RPR思科模块
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS/RPR SPAs are available on high-end Cisco routing platforms and offers the benefits of network scalability with lower initial costs and easy upgrades. The SPAs continues the Cisco focus on investment protection along with consistent feature support, broad interface availability, and leading-edge technology. The SPAs allow different interfaces (POS, ATM, etc.) to be deployed on the same carrier card.
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS/RPR SPAs use Small Form-Factor Pluggable (SFP) interfaces. SFP modules are available in short-reach (2 km), intermediate-reach (15 km), and long-reach (80 km) optics.
Applications SPA-1XOC48POS RPR思科模块
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS and RPR SPAs can be used in multiple applications, including:
• Access and aggregation
• WAN uplinks
• Internet peering
These SPAs feature both packet over SPA-1XOC48POS RPR思科模块SONET/SDH for mesh fiber networks (Figure 2) and Resilient Packet Ring for ring fiber topologies (Figure 3). These SPAs comply with the IEEE 802.17 RPR standard and also support the Spatial Reuse Protocol (SRP) for compatibility with existing Dynamic Packet Transport/Resilient Packet Ring (DPT/RPR) networks.

Key Features and Benefits SPA-1XOC48POS RPR思科模块
The Cisco SPA/SIP portfolio offers many advantages, including:
• 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 SPA-1XOC48POS RPR思科模块
– 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. SPA-1XOC48POS RPR思科模块
– 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 SPA-1XOC48POS RPR思科模块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 respectSPA-1XOC48POS RPR思科模块 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.
