Data Sheet
The OC-12c/STM-4 POS/SDH Line Card is a versatile, high-performance line card well suited for a variety of applications including high-speed WAN uplinks in a CPE deployment, high-speed enterprise backbone, and high-speed uplink for Cisco® 7300 deployment as a medium density, medium speed edge-aggregation router in tier 2 and 3 service provider POPs.
Developed for customers needing a combination of performance and deployment flexibility, the Cisco 7300 is the embodiment of both present day and future requirements for a Mid-Range router. The Cisco 7300 delivers high-performance forwarding and hardware-accelerated services in a compact four rack-unit (4RU), four slot form factor.
Powerful and flexible, the Cisco 7300 provides multiprotocol support, interface granularity, and high-availability features to create a platform that is ideal for deployment in applications such as high-end enterprise routing, medium speed and density leased-line aggregation in service provider tier 2 and 3 POPs, and service provider-managed customer premises equipment (CPE) deployments. Providing WAN connectivity at speeds ranging from DS3 through OC48/STM-16 and LAN connectivity at speeds up to Gigabit Ethernet (via two 10/100/1000 Ethernet ports built into the NSE-100 route processor), the Cisco 7300 supports a wide range of concurrently running applications and lives up to the high standards of the Cisco 7x00 series of Mid-Range routers.
