Introduction

Introduction to the NEXPEED NBG440 router

Overview

Implementing international standard-based ITU-T/ETSI G.SHDSL transmission (G.991.2) with

robust IP routing, concurrent bridging functions and built-in 4 port Ethernet switch, NBG440 is

perfect for mission-critical applications such as compus networking, multimedia services and

network gateway access.

Interoperating with NexComm’s Ethernet-based SHDSL Mini-DSLAM NS4024G, the NBG440

provides a cost effective alternative of Ethernet networking of Point to Multi-Point application for

SMBs that have multiple buildings in a campus-like environment. By leveraging Tag-based VLAN

and STP capabilities of the NBG440, the campus ensures a highly secure and reliable network. By

utilizing the Ethernet-based QoS capabilities the campus can take advantage of voice and video

applications. This application requires no new infrastructure, and results in a low cost, plug and

play solution with low management overhead.

Features

SHDSL is a technology based on the G.SHDSL(G.991.2) standard. NBG440 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 4 ports 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

NEXPEED NBG440 User’s Manual

NexComm Systems, Inc. 6 PAGE

▄Supports TCP/IP, UDP, ICMP, and ARP protocol.

▄Supports HDLC, PPP, Frame Relay and ETHDLC as a transmission protocol.

▄Supports transparent bridging function.

- Functionality of IMUX (Link-multiplexing function)

- IEEE 802.1Q tag-based VLAN

- IEEE 802.1P Priority

▄Supports basic routing function and advanced features.

- Static Routes

- RIP 1 and RIP 2 by routing protocol

- Enables NAT and PAT as the address translation

- Functionality of Load-Balancing and line back-up

▄Offers DHCP Relay and DHCP Server functionality.

▄Supports Proxy ARP function.

▄Offers various methods of filtering function for IP packets.

▄Supports a SNTP (Simple Network Time Protocol) client.

▄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.

▄Front panel LEDs enable the easy check of the interface status.

▄PING utilities enable to check the network status.

▄Offer SHDSL service together with our product series of routers and modems.
