Chapter 1 Overview

The SHDSL router satisfies the needs of multiple users in small/home offices and

remote/branch offices. It provides symmetrical transmission speeds of up to 4.6

Mbps through a SHDSL connection, over a four-wire line. In addition, it supports

up to 16 virtual concurrent connections to multiple destinations. The integrated

four-port switch enables up to four devices to be connected to the LAN.

The SHDSL router can be used for a variety of applications, including video

conferencing, remote training, e-commerce, and other multimedia applications.

Easy configuration and monitoring can be accomplished using the Web browser.

The SHDSL router has full routing capabilities to segment/route IP protocol and is

capable of bridging other protocols. It can be also configured in either server or

client mode enabling point-to-point connectivity between two sites.

1.1 Application

The router can be used for DSLAM and point-to-point applications.

Chapter 2 Installation

2.1 Hardware Installation

The following equipment may be necessary to install the router:

 AC power adapter

A power adapter is shipped with the router.

 LAN connection cable

To connect to the hub, use a straight-through RJ45 cable. To connect to a PC, use

a crossover RJ45 cable.

 Four-wire (8P8C) straight through RJ45 cable

A four-wire (8P8C) straight through RJ45 cable is needed to connect to the LINE

port to the wall outlet.

2.2 Rear-panel Connections

Step 1

Step 2

Step 3

DSL connection

Connect the supplied RJ-45 cable to the port marked LINE at the back of the

SHDSL router. Connect the other end of the cable to your telephone-line wall

outlet. Ensure your computer is turned on before you connect the DSL line to the

router. A green LED on the front of the device labeled LINK will illuminate. If the

SHDSL LINK LED does not illuminate within one minute of it being connected,

check your cable connections to ensure they are correct and securely installed.

Ethernet connection

Insert one end of the RJ45 Ethernet cable into one of the LAN ports marked LAN

on the back of the SHDSL router. Connect the other end of the cable into your

Ethernet Network Interface Card (NIC) installed in your computer. When the

Ethernet connection is established, the correspondent green LED on the front

panel labeled LAN will illuminate. You can connect up to four PCs, by repeating

this process.

Power connection

Connect the supplied external AC adapter into the DC power outlet on the back of

the router. Connect the power supply into your wall outlet or surge protector.

Turn on the power switch. After powering on, the router performs a self-test.

Wait for a few seconds until the test is finished, then the router will be ready to

operate. The POWER indicator on the front of the router will illuminate green to

indicate that power is being supplied to the router.

Caution 1: If the router fails to power up, or it malfunctions, first verify that the

power supply is connected correctly. Then power it on again. If the

problem persists, contact our technical support engineers.

Caution 2: Before servicing or disassembling this equipment always disconnect all

power cords and telephone lines from the wall outlet.
