Cisco ASR 9000 Series Shared Port Adapter
Support
Product Overview
The Cisco
®
Interface Flexibility (I-Flex) design combines shared port adapters (SPAs) and SPA interface
processors (SIPs), taking advantage of an extensible design that facilitates service prioritization for voice, video,
and data services. SPAs provide the physical interfaces for router connectivity ranging from copper, Channelized,
Packet over SONET/SDH (PoS) and ATM. The Cisco ASR 9000 Series SIP provides the physical termination for
the SPAs and accepts up to four half-height and two full-height Cisco SPAs. 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 powerful 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. Figure 1 shows the Cisco ASR 9000 Series SIP.

Modular port adapters and programmable interface processors, which are interchangeable across Cisco carrier
routing platforms, help customers protect network investments and reduce total cost of ownership. The Cisco
SPA/SIP portfolio offers a rich set of quality-of-service (QoS) features for premium service delivery.
Features and Benefits
The Cisco SPA/SIP portfolio offers many advantages, including:
● Industry's most modular, flexible, intelligent interface processors:
◦ Powerful flexibility provides mix-and-match interface types on the same interface processor for consistent
services, independent of access technology.
◦ Pioneering programmable interface processors provide flexibility for the service diversity required in next-
generation networks.
◦ The innovative design provides intelligent delivery of services without compromising on performance.

● Increased speed to service revenue:
◦ Interface breadth (copper, Channelized, PoS and ATM) on a modular interface processor allows service
providers to more quickly roll out new services, helping ensure that all customers large and small receive
consistent, secure, and guaranteed services.
◦ High-density Small Form-Factor Pluggable (SFP) interfaces are featured for high-port-count applications
with reach flexibility. Future optical technology improvements can be adopted using existing SPAs.
