Cisco Network Convergence System 4000 External Connections Unit - Network Management Device - GigE - Plug-in Module - For P/N: NCS4009-SYS-AC, NCS4009-SYS-DC, NCS4016-SYS-AC, NCS4016-SYS-DC - NCS4K-ECU

• Packet switching
  Packet switching includes full IP, MPLS, and MPLS-TP and Carrier Ethernet, supporting 10, 40, and 100 Gigabit Ethernet interfaces with optional OTN (OTU-2, OTU-3, or OTU-4) encapsulation.
• OTN switching
  OTN switching includes full optical channel data unit level 0 (ODU-0) switching with ports supporting SONET/SDH, Ethernet, and Channelized OTN; 10 Gigabit Ethernet (OTU-2), 40 Gigabit Ethernet (OTU-3), and 100 Gigabit Ethernet (OTU-4).
• Ultra-dense integrated DWDM
  This feature offers full DWDM integration with support for IP-over-DWDM features including the Cisco nLight Control Plane Protocol.
• Hybrid traffic
  OTN and packet switching can occur simultaneously, providing the ability to route or switch packet flows within a larger OTN container.
• Superior power efficiency
  Cisco CPAK pluggable transceivers and innovative silicon and power management solutions reduce power draw and increase density.

The Cisco Network Convergence System 4000 (NCS 4000) series is a converged optical service platform providing dense wavelength-division multiplexing (DWDM), Optical Transport Network (OTN), Multiprotocol Label Switching Transport Profile (MPLS-TP), Carrier Ethernet, and label switch router (LSR) or IP multiservice capabilities (Figure 1). It delivers massive scale through a state-of-the-art silicon and system design, while offering dramatic network efficiency and simplification led by innovations in usability, automation, service management, turn-up, and monitoring.
