CHAPTER 1
VMG Introduction
1.1 Overview
The VMG is a VDSL bridge, supporting IEEE 802.3az. VDSL provides fast Internet access over POTS (Plain
Old Telephone Service) analog telephone wires.
As a network bridge (or layer 2), the VMG functions as a switch. There is no IP routing or NAT between
networks, it simply extends the layer 2 domain. The “WAN” port of the router, and the “LAN” port of the
VMG, are all in the same LAN with no routing (or layer 3) network separation.
The VMG supports Zero Configuration Internet Access. Once you connect and turn on the VMG, it
automatically detects the Internet connection settings (such as the VCI/VPI numbers and the
encapsulation method) from the ISP and makes the necessary configuration changes.
1.1.1 Internet Access
Use the gray phone cable to connect the DSL port to a DSL splitter or directly to the telephone wall
outlet. You can have multiple WAN services over one ADSL or VDSL. The VMG cannot work in ADSL and
VDSL mode at the same time.
Note: The ADSL and VDSL lines share the same DSL interface in the VMG.
A computer, gateway, or router can connect to the VMG’s LAN port.
Figure 1 VMG’s Internet Access Application
1.2 Ways to Manage the VMG
Use any of the following methods to manage the VMG.
• Web Configurator. This is recommended for management of the VMG using a (supported) web
browser.
• Simple Network Management Protocol (SNMP). Use for collecting and organizing information about
the VMG and for modifying that information to change the VMG behavior.
• Secure Shell (SSH), Telnet. Use for troubleshooting the VMG by qualified personnel.

Chapter 1 VMG Introduction
VMG4005-B50B User’s Guide

• TR-069 management. Use for remotely managing the VMG.
1.3 Good Habits for Managing the VMG
Do the following things regularly to make the VMG more secure and to manage the VMG more
effectively.
• Change the Web Configurator password. Use a password that is not easy to guess and that consists of
different types of characters, such as numbers and letters. Refer to Section 9.2.1 on page 39 for details
• 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 VMG to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the VMG. You could simply restore your
last configuration. Refer to Section 14.2 on page 51 for details.

the device label).
1Make sure the POWER LED is on (not blinking).
2To set the device back to the factory default settings, press the RESET button for more than five seconds
or until the POWER LED begins to blink and then release it.
When the POWER LED begins to blink, the defaults have been restored and the device restarts.
1.4.5 Wall Mounting
You may need screw anchors if mounting on a concrete or brick wall.
The following figure introduces the specifications of the screws and screws anchors for wall mounting.
Figure 4 Screws & Screw Anchors Specifications
1Select a position free of obstructions on a wall strong enough to hold the weight of the device.
Do NOT wall-mount the VMG over the height of 2 meters.
2Mark two holes on the wall at the appropriate distance apart for the screws.
Be careful to avoid damaging pipes or cables located inside the wall
when drilling holes for the screws.

3If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the full
depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way in - leave
a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the screws all
the way in - leave a gap of about 0.5 cm.
4Make sure the screws are fastened well enough to hold the weight of the VMG with the connection
cables.
5Align the holes on the back of the VMG with the screws on the wall. Hang the VMG on the screws.

The Web Configurator is an HTML-based management interface that allows easy VMG setup and
management via Internet browser. Use Internet Explorer 11 and later versions or Mozilla Firefox 67.0.2 and
later versions or Safari 5.0 and later versions. The recommended screen resolution is 1024 by 768 pixels.
In order to use the Web Configurator you need to allow:
• Web browser pop-up windows from your VMG. Web pop-up blocking is enabled by default in
Windows 10.
• JavaScript (enabled by default).
• Java permissions (enabled by default).
2.1.1 Access the Web Configurator
1Make sure your VMG hardware is properly connected (refer to the Quick Start Guide).
2Launch your web browser. If the VMG does not automatically re-direct you to the login screen, go to
http://192.168.1.1.
3A password screen displays. To access the administrative Web Configurator and manage the VMG,
type the default username admin and password (in the VMG’s label) in the password screen and click
Login. If you have changed the password, enter your password and click Login.

should turn off other applications (for example, using QoS; see Chapter 7 on page 54).
Memory Usage This field displays what percentage of the VMG’s memory is currently used. Usually, this
percentage should not increase much. If memory usage does get close to 100%, the VMG is
probably becoming unstable, and you should restart the device. See Section 14.2 on page
51, or turn off the device (unplug the power) for a few seconds.
