Cisco 8-Port Channelized T1/E1 Shared Port Adapter

The Cisco

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

processors (SIPs), providing an extensible design that helps prioritize 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 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 8-Port Channelized T1/E1 Shared Port Adapter (SPA; refer to Figure 1).

Product Overview

Today’s global enterprise and service provider networks require diverse networking solutions to

meet both economic and evolving connectivity needs. The demand for high-density, cost-effective

solutions increases as corporate intranets expand to include more regional offices and increased

numbers of remote and mobile users.

The Cisco 8-Port Channelized T1/E1 SPA provides one of the greatest densities currently offered

in the industry at 8 ports per SPA and up to 32 ports per SIP. At a cost per T1/E1 port less than

that of a standard serial port with external channel service unit/data service unit (CSU/DSU), the

Cisco 8-Port Channelized T1/E1 SPA is cost-effective for all WAN connectivity.

The SPA is designed to provide a full 8-port channelized solution for the Cisco 6500,7600 and the

12000 Series Routers. The interfaces can be channelized, fractional, or unframed (E1) with up to

256 independent High-Level Data Link Control (HDLC) channels definable for T1 and E1

applications. With these capabilities, the SPA eliminates the need for separate interface types for

separate connection requirements.
