The Cisco® 7304 1-Port OC-12c/STM-4c ATM Line Card delivers the versatility and high performance to benefit a variety of applications. These applications include high-speed WAN uplinks in customer premises equipment (CPE) deployments, high-speed enterprise backbone networks, and high-speed uplinks for the Cisco 7304 Router as a medium-density, medium-speed, edge-aggregation router in Tier 2 and 3 service provider points of presence (POPs). The line card uses Small Form-Factor Pluggable (SFP) optics to provide a range of options.
Cisco 7304 1-Port OC-12c/STM-4c ATM Line Card
Developed for customers that need a combination of performance and deployment flexibility, the Cisco 7304 meets current and future requirements for a midrange router. The Cisco 7304 delivers high-performance forwarding and hardware-accelerated services in a compact 4-rack-unit (4-RU), 4-interface-slot form factor.
Powerful and flexible, the Cisco 7304 provides multiprotocol support, interface granularity, and high-availability features in a platform that is ideal for deployment in various applications such as high-end enterprise routing, medium-speed and medium-density leased-line aggregation in service provider Tier 2 and 3 POPs, and service provider-managed CPE deployments (Table 1). Providing WAN connectivity at speeds ranging from DS-3 through OC-48/STM-16, and LAN connectivity at speeds up to Gigabit Ethernet (through two 1000 Ethernet ports built into the Cisco Network Services Engine NSE-100 route processor), the Cisco 7304 supports a wide range of concurrently running applications and lives up to the high standards of the Cisco 7000 Series of midrange routers.
