Cisco 2-Port and 4-Port Clear Channel T3/E3
Shared Port Adapters

The Cisco

I-Flex approach combines shared port adapters (SPAs) and SPA interface

processors (SIPs), providing an extensible design that enables service prioritization for

data, voice, and video 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 4-Port and 2-Port Clear Channel T3/E3 SPAs (Cisco Clear Channel T3/E3 SPAs;

refer to Figure 1).

Product Overview

Demand for high-capacity corporate backbones, for high-speed access to the global Internet, and

for trunking connections for service provider internetworking has led to a growth in clear channel

T3/E3 connections that has outpaced all other types and speeds of leased lines. This growth

places tremendous strain on service providers and network managers who must provision and

manage new T3/E3 connections. The Cisco Clear Channel T3/E3 SPAs for the Cisco 7304, 6500,

7600, and 12000 Series Routers offer high-density, highly manageable T3/E3 line connectivity and

termination. With integrated line-interface data service units (DSUs) that allow T3/E3 lines to be

directly terminated on a Cisco router, the Cisco Clear Channel T3/E3 SPAs simplify T3/E3 line

management, reduce provisioning costs, and make valuable rack space available.

The Cisco Clear Channel T3/E3 SPAs are designed to provide direct connectivity to T3/E3 lines for

full-duplex communications at the T3 rate of 44.736 MHz or E3 rate of 34.368 MHz. They are

available in 2- and 4-port options. The ports are configurable as either all T3 or all E3. To support

the widest range of operational environments and to offer the greatest flexibility in provisioning

clear channel T3/E3 connections, the Cisco Clear Channel T3/E3 SPAs take a groundbreaking
