Cisco NCS 4201 and
Cisco NCS 4202 Overview
The Cisco NCS 4201
and NCS 4202 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 and NCS 4202 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 .
