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. This data sheet contains the specifications for the
Cisco 1-Port Channelized OC-3/STM-1 circuit emulation over packet and ATM SPAs
(refer to Figure 1).

Product Overview
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 (Packet over SONET/SDH
[POS], ATM, Ethernet, and so on) 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).
