Cisco 7300 2 and 4-Port OC-3c/STM-1 Packet over SONET/SDH

Data Sheet

 

Line-Rate, High-Density OC-3c/STM-1 Connectivity Edge Routing with High-Touch IP Service Delivery

Product Overview

The Cisco^® 7304 Router is designed for the network edge where high-performance IP services are required to enable profitability, service differentiation, and business agility. Using a compact, 4-rack-unit (4-RU), modular (4-slot) form factor, the Cisco 7304 Router delivers high-touch IP services at optical speeds necessary for applications in the high-end enterprise, service provider edge, and for service provider-managed customer premises equipment (CPE).

High-performance services are critical in these implementations, and the Cisco 7304 Router delivers an evolving set of hardware-accelerated IP services through the Parallel Express Forwarding (PXF) IP Services Processor technology patented by Cisco Systems^®. The Cisco 7304 Router provides a range of optical connectivity from OC-3/STM-1 to Gigabit Ethernet, OC-48 performance, an architecture engineered for high availability, and multiprotocol support. With two Gigabit Ethernet ports built into the system, the Cisco 7304 Router is the optical evolution of Cisco 7x00 Series routers

The Cisco 7304 OC-3c/STM-1 Packet over SONET /SDH Line Card (Figure 1), in two or four ports, is a modular, versatile card suited for a variety of solutions: from WAN uplinks in a CPE deployment to aggregation at the edge where service provider and enterprise networks meet. Using the Cisco Network Services Engine (NSE)-100 Route Processor on the Cisco 7304 Router, this line card can use multiprotocol capability from Cisco IOS^® Software, and PXF technology to deliver hardware-accelerated IP network services.
