Cisco 1-Port Channelized OC-3/STM-1 Circuit Emulation Over Packet and Channelized ATM Shared Port Adapter - expansion

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, which 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.

The Cisco 1-port Channelized OC3/STM-1 circuit emulation over packet and ATM 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 to be deployed on the same interface processor.

The Circuit Emulation over Packet (CEoP) SPAs provide a new service offering. These SPAs provide bit-transparent data transport that is completely protocol independent.

For the first time, this allows network administrators to use their existing IP/MPLS network to provide leased-line emulation services or to carry data streams or protocols that do not meet the format requirements of other multiservice platform interfaces. In addition, these SPAs can be used for low-speed ATM services, including Inverse Multiplexing over ATM (IMA).
