Cisco Network Convergence System 4202 Shelf Assembly - Network Management Device - TDM, 10 GigE, SONET, PDH, SDH - Front To Back Airflow - 1U - Rack-mountable - NCS4202-SA=

• Support for TDM and SONET/SDH migration to modernized packet-based optical metro network
  Provides cost-effective delivery of CEM and Carrier Ethernet capabilities over a redundant and protected packet-based network (MPLS/FlexLSP).
• Metro Carrier Ethernet aggregation
  Enables the service flexibility and delivery of Layer 2, Layer 3, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
• Industry-leading, carrier-class CEM technology
  Delivers any-to-any connectivity through a packet-based network (MPLS/Flex LSP) using TDM, PDH, SONET/SDH, and Carrier Ethernet (FE, GE, and 10GE) interfaces.
• Next-generation access network with fully distributed and unique packet capabilities
  Supports state-of-the-art Pseudowire Emulation Edge-to-Edge (PWE3), Hierarchical Quality of Service (H-QoS), and next generation IP/MPLS.
• Operation efficiency with end-to-end network management
  Supported by the Evolved Programmable Network Manager (EPN-M), which enables business agility and operational efficiencies through automated device operations, fast provisioning, and proactive assurance.
• Flexible and compact platform
  Designed with a compact 1RU form factor, the Cisco NCS 4202 can be deployed in space-constrained locations such as ETSI 300-mm deep cabinets, and the extended temperature range feature supports deployment in locations with minimum environmental control.

Legacy copper access networks, based on Plesiochronous Digital Hierarchy (PDH), and optical metro networks, based on Synchronous Optical Network (SONET) or Synchronous Digital Hierarchy (SDH) technologies, set the standards for reliability, capacity, and efficiency, transporting time-division multiplexing (TDM) traffic and carrying voice and data services. Service providers and carriers are nonetheless faced with many challenges and limitations imposed by these legacy networks and need alternatives for migrating their circuit-switched transport networks to future-proof packet-based networks.
The Cisco NCS NCS 4202 series Network Convergence Systems are full-featured, compact 1RU high converged access platforms designed for the cost-effective delivery of TDM to IP/MPLS migration services. These temperature-hardened, high-throughput, small-form-factor, low-power-consumption systems are optimized for circuit emulation and business applications. NCS 4202 systems allow service providers to deliver dense scale in a compact form factor and unmatched CEM and Carrier Ethernet 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.
