Cisco Shared Port Adapter

The extensible Cisco® I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs), enabling 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.
