Cisco 2-Port Channelized T3/E3 Circuit Emulation Over
Packet and Channelized ATM Shared Port Adapter

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. This data sheet contains the specifications for the

Cisco 2-Port Channelized T3/E3 Circuit Emulation over Packet (CEoP) and ATM SPA

(Figure 1).

Product Overview

The Cisco 2-Port Channelized T3/E3 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 easy upgrades. The Cisco SPA/SIP portfolio continues Cisco’s 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, etc.) to be deployed on the same interface processor.
