Cisco 1-port Channelized OC48/STM-16 SPA
The Cisco® I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs) using an extensible design that enables service prioritization for voice, video, and data services. Enterprise and service provider customers can use the 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 Channelized OC48/STM-16 SPA.
The Cisco 1-Port Channelized OC-48/STM-16 SPA is available on high-end Cisco routing platforms offering the benefits of network scalability with lower initial costs and ease of upgrades. The Cisco SPA/SIP portfolio continues the Cisco 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.
<b>Applications</b>
Internet traffic continues to grow at an explosive rate - with the number of users doubling each year. This unsurpassed growth is increasing the demand for higher-capacity interfaces from OC-3/STM-1 to OC-48/STM-16. In addition, POS enables efficient transport of IP traffic and uses SONET/SDH concatenated payloads (that is, STS-3c/VC-4, STS-12c/VC-4-4c, or STS-48c/VC-4-16c) to achieve a higher order of statistical multiplexing.
Service providers face the challenge of meeting customer demand by building scalable, feature-rich edge networks that can deliver value-added services such as Multiprotocol Label Switching VPNs (MPLS VPNs); voice, video, and data integration; and tiered service offerings at all interface rates without compromising density or line-rate performance. The Cisco Channelized OC-48/STM-16 SPA channels one OC-48 or STM-16 interface into DS-3, E3, OC-3c, STM-1c, OC-12c, or STM-4c channels and provides an extensive set of service-enabling edge features while performing at line rate simultaneously on all ports.
