Introduction
Introduction to the NEXPEED NR304G-4W router
Overview
The NR304G-4W router with SHDSL is a full-featured, stand-alone, router for connecting diverse
local area networks(LANs) to the Internet and other remote networks. You will have a fast
SHDSL(Symmetric High-speed Digital Subscriber Line) connection between your LAN and ISP’s
network of high-speed digital facilities. SHDSL is a technology based on the G.SHDSL(G.991.2)
standard. NR304G-4W supports a packet-based network technology that allows high-speed
transmission over twisted-pair copper wire between an Internet service provider central office and
a customer site or on local loops created within a building.
The NR304G-4W operates over 2-wire and 4-wire lines, enabling service over any copper
infrastructure. The NR304G-4W supports multiple data rates and infrastructures, operating at
speeds of up to 2.3 Mbps over 2-wire and up to 4.6 Mbps over 4-wire lines.
Also it can operate both as a CO(Central Office Equipment) and as a RT(Remote Terminal).

Features
SHDSL is a technology based on the G.SHDSL(G.991.2) standard. NR304G-4W supports a
packet-based network technology that allows high-speed transmission over twisted-pair copper
wire between an Internet service provider central office and a customer site or on local loops
created within a building.
The features are as follows:
▄Supports 1 port of 10/100M Ethernet LAN of automatic sensing
▄Supports ITU-T G.991.2 (G.SHDSL) standard
▄Supports identical user data rates in both upstream and downstream directions (symmetric
technology) and vary from 200 Kbps:
- up to 2.3 Mbps in two-wire(one pair) mode
- up to 4.6 Mbps in four-wire(two pair) mode
▄Supports both bridging and routing functions : It can bridge nonrouted traffic such as IPX or
NETBEUItraffic
▄Front panel LEDs enable the easy check of the interface status
▄PING utilities enable to check the network status
▄Can be configured either by serial console or Telnet S/W
▄HTTP server enables WEB based management.
▄Supports SNMP MIB1 and MIB2 and monitoring through SNMP-base application
▄Supports TCP/IP, UDP, ICMP, and ARP protocol
▄Supports HDLC, PPP, Frame Relay and ETHDLC as a transmission protocol
▄Supports RIP1and RIP2 by IP routing protocol
▄Offers DHCP Relay and DHCP Server functionality
▄Enables NAT and PAT as the address translation
▄Functionality of Load-Balancing and line back-up
▄Functionality of IMUX (Link-multiplexing function)
▄Supports Proxy ARP function
▄Offers various methods of filtering function for IP packets
▄Offer SHDSL service together with our product series of routers and modems.
