1 Introduction

The DSL-2750E supports multiple line modes. It provides four

10/100 base-T Ethernet interfaces at the user end. The

device provides high-speed ADSL broadband connection to

the Internet or Intranet for high-end users, such as net bars

and office users. It provides high performance access to the

Internet, downstream up to 24 Mbps and upstream up to 1

Mbps.

The device supports WLAN access, such as WLAN AP or

WLAN device, to the Internet. It complies with IEEE

802.11,802.11b/g specifications, WEP, WPA, and WPA2

security specifications.

Pay attention to the power load of the outlet or prolonged

lines. An overburden power outlet or damaged lines and

plugs may cause electric shock or fire accident. Check

the power cords regularly. If you find any damage,

replace it at once.

Proper space left for heat dissipation is necessary to

avoid damage caused by overheating to the device. The

long and thin holes on the device are designed for heat

dissipation to ensure that the device works normally. Do

not cover these heat dissipation holes.

Do not put this device close to a place where a heat

source exits or high temperature occurs. Avoid the

device from direct sunshine.

Do not put this device close to a place where it is over

damp or watery. Do not spill any fluid on this device.

Do not connect this device to any PCs or electronic

products, unless our customer engineer or your

broadband provider instructs you to do this, because any

wrong connection may cause power or fire risk.

Do not place this device on an unstable surface or

support.

2 Hardware Installation

Step 1 Connect the DSL port of the device and the Modem

port of the splitter with a telephone cable. Connect the

phone to the Phone port of the splitter through a

telephone cable. Connect the incoming line to the

Line port of the splitter.

The splitter has three ports:

Line: Connect to a wall phone port (RJ-11 jack).

Modem: Connect to the DSL port of the device.

Phone: Connectto a telephone set.

Step 2 Connect the LAN port of the device to the network

card of the PC through an Ethernet cable

(MDI/MDIX).

Note:

Use twisted-pair cables to connect with the Hub or switch.

Step 3 Plug one end of the power adapter to the wall outlet

and connect the other end to the Power port of the

device.

Connection 1: Figure 3 displays the application diagram for

the connection of the device, PC, splitter and telephone sets,

when no telephone set is placed before the splitter.
