Setting Up the Hardware

 

The Model DG814 gateway incorporates a four-port switch for connecting to your local network. 
To connect the Model DG814 gateway to your LAN:

Connect up to four PCs directly to any of the four Local ports of the gateway using standard 
Ethernet cables.

If your local network consists of more than four computers, you will need to connect your gateway 
to another hub or switch:

Connect any Local port of your gateway to any port of an Ethernet hub or switch using a 
standard or crossover Ethernet cable.

Because the gateway incorporates Auto Uplink

TM

 technology (also called Auto MDI/MDI-X), 

it is capable of automatically sensing the polarity of the Ethernet connection. You can 
therefore connect to the other hub’s normal or uplink port using a standard or crossover 
Ethernet cable. The Local port of your Model DG814 gateway will automatically configure 
itself properly.

Connecting to Your ADSL Service and Telephone Provider

The ADSL and telephone connections may vary by region. 

ADSL through a modular RJ-11 wall jack

.

To install the Model DG814 gateway directly to the wall jack without installing a telephone:

1.

Connect the provided telephone cable to the wall jack.

2.

Connect the other end of the telephone cable to the ADSL port on the gateway.

To install both the Model DG814 gateway and a telephone:

1.

Plug the “LINE” connection from the included microfilter into the wall jack.

2.

Connect the “DSL” jack of the microfilter to the ADSL port of your gateway using the 
telephone cable provided.

3.

Connect the “PHONE” side of the microfilter to your telephone, using your existing telephone 
cable.

Note: 

The wall jack attached to the ADSL port of the gateway must provide the ADSL 

signal on the inner pair of wires (pins 2 and 3 of the 4-pin jack). If this is not the case, a 
swapper (not included) is necessary to move the connection to the inner pair.
