Notes 142 Cisco 7301 Series The Cisco 7301 Series Router is a compact, high-performance single-rack-unit (1 RU) router coupled with a broad set of interfaces and Cisco IOS Software features, which makes it ideal for both service providers and enterprise applications. Cisco 7301 Series is based on the Cisco 7200 NPE-G1 engine. The Cisco 7301 packs high performance in a space- and power-efficient chassis that includes a single Cisco 7000 Series port adapter slot, three onboard Gigabit Ethernet (copper or optical) or Fast Ethernet ports, and new high-speed bus technologies. The key features of the Cisco 7301 Router are: • Compact, power-efficient 1 RU form factor • Single Cisco 7000 Series port adapter slot • Complete Cisco IOS Software feature support • Three onboard Gigabit Ethernet (copper or optical) or Fast Ethernet ports • Pluggable Gigabit Ethernet optics (Small Form-Factor Pluggable [SFP] optics) • Up to 1 GB of available DRAM, supporting up to 1 million routes • Up to 256 MB of removable compact Flash memory • Front-to-back airflow and single-sided management Next-Generation Policy and Subscriber Solution The Cisco 7301 supports Cisco Intelligent Services Gateway (ISG), the next-generation policy and subscriber management solution to deliver dynamic session awareness. Cisco ISG supports IP, Ethernet, ATM, Multiprotocol Label Switching (MPLS), and VPN architectures, whether the business model is for retail, wholesale, or business services. Cisco ISG allows for zero-touch provisioning, and provides the per-flow granularity and dynamic control required for triple-play services. Unlike some competitive offerings, Cisco ISG is standards-based for multi-vendor deployment. With RADIUS Change of Authorization (RFC 3576), subscriber profiles can be changed dynamically based on user self-management (through a Web portal) or through an OSS process. Network utilization improves because per-subscriber bandwidth needs are managed dynamically, increasing customer satisfaction. 143
