The IPGate NED, a network edge IP gateway, is a compact member of the IPGate product family designed for use in network edge applications. Like its larger family members, the IPGate-NED reliably transports legacy Time Division Multiplexing (TDM) and other circuit-based applications across converged IP networks therefore delivering the cost, efficiency and reliability benefits of IP migration using standards-based technologies. The IPGate-NED accommodates a wide variety of legacy analog and digital interfaces at configurable data rates ranging from 50 bps to 34 Mbps through the use of standards-based IP encapsulations. One rack unit high it accepts up to four user interface cards or port cards.

 IPGate NED Differentiators:

  • Standards-based encapsulation: CESoP, TDMoP, SAToP, and PWE3
  • Industry’s widest repertoire of supported legacy data and voice interfaces
  • Multiple clocking options
  • Enables IP transport over commercial IP routers and switches
  • User-friendly management software with intuitive HMI
  • IPv4 and IPv6 support
  • Redundant network connections and power supplies
  • FIPS 140-2 Encryption (optional)

Network Edge IP Gateway Uses

  • Serial Circuit migration to IP networks (Everything-over-IP)
  • Virtual matrix switch: non-blocking any-to-any connections
  • Long Haul Secure Communication (LHSC) over IP
  • Radio-over-IP
