Introducing the Device

1.1

Overview

The VMG1312-B Series is a wireless VDSL router and Gigabit Ethernet gateway. It has a DSL port

and a Gigabit Ethernet port for super-fast Internet access. The Device supports both Packet

Transfer Mode (PTM) and Asynchronous Transfer Mode (ATM). It is backward compatible with ADSL,

ADSL2 and ADSL2+ in case VDSL is not available.

Only use firmware for your Device’s specific model. Refer to the label on

the bottom of your Device.

The Device has two USB ports for sharing files via a USB storage device, sharing a USB printer, or

connecting a 3G dongle for a WAN backup connection.

•

The VMG1312-B10A works over the analog telephone system, POTS (Plain Old Telephone

Service).

•

The VMG1312-B30A works over ISDN (Integrated Services Digital Network) or T-ISDN (UR-2).

1.2

Ways to Manage the Device

Use any of the following methods to manage the Device.

•

Web Configurator. This is recommended for everyday management of the Device using a

(supported) web browser.

•

TR-069. This is an auto-configuration server used to remotely configure your device.

1.3

Good Habits for Managing the Device

Do the following things regularly to make the Device more secure and to manage the Device more

effectively.

•

Change the password. Use a password that’s not easy to guess and that consists of different

types of characters, such as numbers and letters.

•

Write down the password and put it in a safe place.

•

Back up the configuration (and make sure you know how to restore it). Restoring an earlier

working configuration may be useful if the device becomes unstable or even crashes. If you

forget your password, you will have to reset the Device to its factory default settings. If you

backed up an earlier configuration file, you would not have to totally re-configure the Device. You

could simply restore your last configuration.

Applications for the Device

Here are some example uses for which the Device is well suited.

1.4.1

Internet Access

Your Device provides shared Internet access by connecting the DSL port to the

DSL

or

MODEM

jack on a splitter or your telephone jack. You can have multiple WAN services over one ADSL or

VDSL. The Device cannot work in ADSL and VDSL mode at the same time.

Note: The ADSL and VDSL lines share the same WAN (layer-2) interfaces that you

configure in the Device. Refer to

Section 6.2 on page 70

for the

Network Setting

screen.

Computers can connect to the Device’s LAN ports (or wirelessly).

Figure 1

Device’s Internet Access Application

You can also configure IP filtering on the Device for secure Internet access. When the IP filter is on,

all incoming traffic from the Internet to your network is blocked by default unless it is initiated from

your network. This means that probes from the outside to your network are not allowed, but you

can safely browse the Internet and download files.

1.4.2
