Cisco 4-Port and 8-Port OC-3c/STM-1 Packet over SONET Shared
Port Adapters
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 improved slot
economics resulting from modular port adapters 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. This data sheet contains the specifications for the Cisco 4/8-Port OC-
3c/STM-1 Packet over SONET SPAs (Cisco 4/8-Port OC-3 POS SPAs; refer to Figure 1).
