Cisco NCS 540 Small Density Routers are temperature-hardened, conformal-coated platforms with advanced timing (Class C), security, and QoS features that revolutionize sub-100G routing by bringing the power of the IOS XR operating system to 3G/4G/5G cell sites (CSRs) and ease "IP" fication of Radio Access Network (RAN) and small-cell backhaul.

Product overview

The next phase of the network traffic explosion will be driven by use cases that make massive demands on communication service providers. Not only do these new-age applications stipulate greater data bandwidth, but they also need to be complemented by ultra-reliable, low-latency communications to deliver use cases like AR/VR media, UltraHD and new multimedia consumer experiences, massive Internet of Things (IoT), tactile internet, smart cities, AI surveillance, smart health, and Machine-to-Machine (M2M) applications such as smart meters.

Cisco Network Convergence System 540 (NCS 540) Small Density Routers, part of the larger NCS 540 router family, are designed for cost-effective delivery of next-generation services and applications for mobile and wireline. These routers are sub-100G-bandwidth, cost-effective, native-25G, carrier-class, I-Temp, conformal-coated, ETSI-compliant, ultra-low-power, devices capable of Class-C timing, best-in-class security, service exposure using NC/YANG, streaming telemetry, and flexible rollouts using SDN. Built for deployment in any-gen RAN backhaul, sub-6 5G cell sites, Fixed-Wireless Access (FWA), small-cell backhaul, FTTx, utilities, mission-critical enterprise applications, and low-speed Ethernet rings, the three variants of NCS 540 Small Density Routers support a programmable SR (segment routing) fabric and EVPN (Ethernet Virtual Private Network) as overlay for a unified end-to-end architecture with cross-domain orchestration via the industry-leading IOS XR software bundled with best-in-class services.
