Overview
The Cisco NCS 4201 Network Convergence Systems are full-featured, compact one-RU high converged
access platforms designed for the cost-effective delivery of TDM to IP or MPLS migration services. These
temperature-hardened, high-throughput, small-form-factor, low-power-consumption systems are optimized
for circuit emulation (CEM) and business applications. NCS 4201 chassis allow service providers to deliver
dense scale in a compact form factor and unmatched CEM and Carrier Ethernet (CE) capabilities. They also
provide a comprehensive and scalable feature set, supporting both Layer 2 VPN (L2VPN) and Layer 3 VPN
(L3VPN) services in a compact package.
