The NE-600-EFM 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 NE-600-EFM ensures high reliability, low OPx, and maximum throughput. EFM copper bonding technology enables the delivery of higher bandwidth at longer distances over multiple copper pairs – an excellent alternative where fiber is not economically feasible and other technology such as T1 or T3 is not able to meet bandwidth requirements.

This “Ethernet-pure” solution provides a seamless integration today for tomorrow’s networks. The NE600 extends the reach of Ethernet services using bonded copper pairs for an aggregate bandwidth of over 61Mbps (TC-PAM 128) using only 4 pairs. 8-pairs can be used in the drop and continue repeater configuration.

Designed using standards-based EFM technology (2BASE-TL), deployment of Ethernet services using the NE600 is quick and simple. Typically used in point-to-point and drop/continue connections between offices, the NE600 provides symmetrical connectivity that is ideal for enterprises 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 NE600 operates in either EFM mode or ATM mode. It is designed to deliver business class Ethernet Service under EFM mode while providing the flexibility to be compatible with an existing DSLAM infrastructure under ATM mode. The NE600 management is supported by a comprehensive Industrial Command Line Interface (ICLI), Telnet, user-friendly GUI-based Web Browser, and SNMP. The NE600 provides future-proof features meeting Ethernet Quality of Service (QoS) and Class of Service (CoS) requirements by utilizing 802.1q VLAN capabilities, four levels of priorities, traffic flow control, and rate control. This traffic management and QoS features enable service providers to offer highly profitable and value-added services to a vast majority of business and institutional sites.

The Embedded Internet Device Support System (EIDSS) option allows the user to easily setup an integral terminal server without any additional hardware and also deploy many other secure IoT applications.
