Cisco NCS 4202 Shelf Assembly - 4x10GE + 12x GE/FE + 1 IM Slot (1 RU) NCS4202-SA

Designed for circuit-switched network migration and business applications, the Cisco® NCS 4201 and NCS4202 Series deliver best-in-class circuit emulation (CEM) and Carrier Ethernet capabilities. 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.
