Compact, Affordable Carrier Routing System
The Cisco CRS 4-Slot Single-Shelf System is a compact 140-Gbps router. It extends the network core to regional Class 3 and 4 central offices, multi-system operator (MSO) hub locations, and data center peering sites. The 4-slot system represents a smaller, more cost-effective configuration of the Cisco Carrier Routing System.
