The Cisco
®
CRS-3 Carrier Routing System offers industry-leading performance, advanced services intelligence, an
environmentally conscious design, and system longevity. The Cisco CRS-3 is powered by the Cisco QuantumFlow
Array
– a chipset architecture based on multidimensional engineering and Cisco IOS

XR Software, a unique self-
healing, distributed operating system.
Packet-based data communications are being replaced by video and rich media traversing the IP Next-Generation
Network (NGN) in multiple directions, straining the architectural foundations of both public and private networks
serving businesses and consumers. As part of the medianet, a media-aware Cisco IP NGN, the Cisco CRS-3 delivers
continuous, always-on operations and scales easily from numerous single-chassis form factors to a massive multi-
chassis system. Its highly efficient design conserves power, cooling, and rack-space resources while optimizing
bandwidth capacity. The Cisco CRS-3 is compatible with the CRS-1, protecting investments for decades to come.
This data sheet provides detailed product specifications for the Cisco CRS-3 24-Slot Fabric-Card Chassis (FCC).
This FCC is an important element of the Cisco CRS-3 multichassis system because it contains the second-stage
switching fabric that interconnects multiple Cisco CRS-3 16-slot single-shelf systems. The interconnectivity of
FCCs and Cisco CRS-3 16-slot single-shelf systems allows the Cisco CRS-3 to gracefully scale from 4.48 to 322
Tbps of system capacity. For more information about the Cisco CRS-3 or about other interfaces available for the
