EC-NE400 Network Extender

Hardened G.SHDSL.bis Network Extender



  • Extending Ethernet to first mile sites over existing traffic, transportation, and enterprise copper infrastructure
  • Point-to-Point
  • Low cost plug and play solution for extending high-speed communications over long distances using a single twisted pair of wire
  • Extends the distance of 10/100 Ethernet/Cat 5 video, audio, and control systems up to 22,000 feet
  • Simultaneously supports video and high-speed data services
  • Does not require PC or Software setup
  • Easily accommodates Access Control System data or data streams from serial data to TCP/IP converters for security, building controls, or plant process equipment
  • Inter-modem Data Link allows LT-400 management of remote end (NT-400)


The NE400 Network Extender is designed to provide bonded high-speed Ethernet in the First Mile services using g.SHDSL.bis on existing copper infrastructure. It is a bridge-mode modem that delivers Ethernet services with symmetrical bandwidth at rates up to 15.3 Mbps/ pair.

The NE400 ensures high reliability, low OPx, and maximum throughput. EFM copper technology enables the delivery of higher bandwidth at longer distances over copper pairs – an excellent alternative where fiber is not economically feasible and other technology such as T1 or E1 is not able to meet bandwidth requirements.

This “Ethernet-pure” solution provides a seamless integration today for tomorrow’s networks. The NE400 extends the reach of Ethernet services using copper pairs for an aggregate bandwidth of over 15Mbps (TC-PAM 128) using only 1 pair over long distances. The rate is adaptive depending on the length and quality of the line; rates can be fixed if desired.

Designed using standards-based EFM technology (2BASE-TL), deployment of Ethernet services using the NE400 is quick and simple. Typically used in point-to-point and drop/continue connections between offices, the NE400 provides symmetrical connectivity that is ideal for enterprise to deliver business-class Ethernet service. User-friendly Ethernet makes it possible to save unnecessary truck rolls and minimize training costs leading to reduced risk and quick ROI.

The NE400 operates in EFM mode. It is designed to deliver business class Ethernet Service. The NE400 management is by user-friendly CLI.  Firmware upgrade via inter-modem data link. Local monitoring is possible using front panel access port or remotely via the web using optional Telnet or SSH.
