Chapter 4: Connecting the ADSL Gateway

Connecting the Gateway to a Computer

ADSL Gateway

3.

Connect one end of an Ethernet network cable to one of the Ethernet ports (labeled 1-4) on the back of the

Gateway, and the other end to an Ethernet port on a computer.

Repeat this step to connect more computers, a switch, or other network devices to the Gateway.

4.

Connect the power adapter to the Gateway’s Power port, and then plug the power adapter into a power outlet.

Press the Power button to turn on the Gateway.

The Power LED will immediately light up green. The Power LED will flash for a few seconds, and then it will be

solidly lit when the self-test is complete. If the LED flashes for one minute or longer, see “Appendix A:

Troubleshooting.”

5.

Power on one of your computers that is connected to the Gateway.

Go to “Chapter 5: Configuring the ADSL Gateway.”

NOTE:

You should always plug the Gateway’s power adapter into a power strip with

surge protection.

button to cancel your changes.

Internet Setup

•

PVC Connection. If your ADSL account provides multiple permanent virtual circuits (PVCs), use this control to

specify the one you will configure. The Gateway can handle up to eight PVCs. They may be used to carry

different services or connect to different networks. Each PVC is identified by a unique combination of VCI and

VPI numbers (see “Virtual Circuit,” below).

•

Internet Connection Type. The Gateway supports six Encapsulation methods: RFC 1483 Bridged, RFC 1483

Routed, IPoA, RFC 2516 PPPoE, RFC 2364 PPPoA, and Bridged Mode Only. Select the appropriate type of

encapsulation from the drop-down menu. Each
