Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco® I-Flex approach combines shared port adapters (SPAs) and SPA interface processors (SIPs), providing an extensible design that enables service prioritization for data, voice, and video 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 I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. 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-Port OC-192c/STM-64c POS/RPR Shared Port Adapter (Cisco 1-Port OC-192 POS/RPR SPA; refer to Figure 1).

Product Overview
The Cisco 1-Port OC-192 POS/RPR SPA is available on high-end Cisco routing platforms, offering the benefits of network scalability with lower initial costs and easy upgrades. The Cisco SPA/SIP portfolio continues Cisco's focus on investment protection along with consistent feature support, broad interface availability, and the latest technology. The Cisco SPA/SIP portfolio allows different interfaces (packet over SONET/SDH [POS], ATM, Ethernet, etc.) to be deployed on the same interface processor.
The Cisco 1-Port OC-192 POS/RPR SPA provides 10-Gbps Small Form-Factor Pluggable (XFP) interfaces in addition to fixed interfaces. SPA configurations are available to support multiple optical reaches from 300 meters to 80 kilometers.
Applications
The Cisco 1-Port OC-192 POS/RPR SPA can be used in multiple applications, including:
• Access and aggregation
• WAN uplinks
• Internet peering
The Cisco 1-Port OC-192 POS/RPR SPA features both POS for mesh fiber networks (Figure 2) and Resilient Packet Ring (RPR) for ring fiber topologies (Figure 3). This SPA complies with the IEEE 802.17 RPR standard and also supports the Spatial Reuse Protocol (SRP) for compatibility with existing Dynamic Packet Transport (DPT)/RPR networks.

Features and Benefits
The Cisco SPA/SIP portfolio offers many advantages, including:
– Superior flexibility, supporting 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 supports intelligent service delivery without compromising on performance.
• Increased speed to service revenue
– The scalable, programmable Cisco architecture extended to 10 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 roll out new services more quickly, helping ensure that 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.
• Dramatically improved return on your routing investment
– Improved slot economics and increased density reduce capital expenditures (CapEx).
– The ability to easily add new interfaces as they are needed enables a "pay-as-you-grow" business model.
– 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.

The OC192 Cisco POS/RPR SPA supports 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. Table 2 lists the modes supported on various platforms and software releases at the time of publication of this data sheet. The table shows the earliest supporting release of each platform and does not provide details with respect to the SIPs on which the SPA is supported. This data sheet 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.
