SHARED PORT ADAPTERS

The Cisco

I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs), leveraging an

extensible design that enables service prioritization for voice, video and data 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. I-Flex enhances speed-to-service revenue

and provides a rich set of QoS features for premium service delivery while effectively reducing the overall cost of ownership.

This data sheet contains the specifications for the Cisco 5-Port, 8-Port, and

10-Port Gigabit Ethernet SPAs (Cisco GE SPAs;

refer to Figure 1).

PRODUCT OVERVIEW

The Cisco 5-Port, 8-Port, and 10-Port GE SPAs are 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 deployment of different interfaces

(packet over SONET/SDH [POS], ATM, Ethernet, etc.) on the same interface processor.

Gigabit Ethernet (GE) interfaces are commonly used for interconnecting routers or other devices within a central office, data center, or in a

metropolitan-area network (MAN). Cisco offers an extensive variety of 1000BASE-X Gigabit Ethernet SPAs to meet customers’ needs for various

applications. With Cisco GE SPAs, users can mix and match SPA ports with other types of interfaces in the same slot. Each SPA provides standards-

based Gigabit Ethernet implementation for compatibility and interoperability.

APPLICATIONS

The Cisco GE SPAs can be used in multiple applications, including:

•

Inter- and intra-point of presence (POP) aggregation

•

Metro Ethernet

•

Internet peering
