Data Sheet

Product Overview

The Cisco® 7304 2-Port OC-3/STM-1 ATM Line Card (Figure 1) is a versatile, high-performance line card that is well suited for a variety of applications. These applications include high-speed WAN uplinks in customer premises equipment (CPE) deployments, high-speed enterprise backbones, and high-speed uplinks for deploying the Cisco 7304 Router as a medium-density, medium-speed, edge-aggregation router in Tier 2 and 3 service provider points of presence (POPs).

Developed for customers that need a combination of performance and deployment flexibility, the Cisco 7304 Router meets current and future requirements for a midrange router. The Cisco 7304 Router delivers high-performance forwarding and hardware-accelerated services in a compact four-rack-unit (4-RU), four-interface slot form factor.
