Installation Instructions
1.1 Important! Before you Begin
Before installing your X5 ADSL modem, you must have DSL
service enabled on your telephone line. To do this, you need to
sign up with a DSL service provider. They will arrange to have
DSL enabled, and provide you with a User Name and Password (if
required) and the Communications Settings necessary to log on to
their network.
You will need your User Name and Password to complete the
installation, so please make sure you have them at hand.
User Name _________________________
Password _________________________
The following table lists some DSL broadband communications
settings. This table is intended for reference only. Typically you
should not need to enter this information; it should be
automatically supplied if needed as part of your service provider’s
installation procedure.

navigate to another page.

Chapter 1: Installation Instructions 13
Using Phone Filters
You should use a filter with each device—phone, fax machine,
analog modem, etc.—that is sharing the DSL-enabled line, because
this prevents the device from receiving noise when the DSL
modem is on. For all other devices on the DSL-enabled line, plug
the device’s phone cord into the filter’s PHONE end, and plug the
filter’s LINE end into the wall jack. Some X5 models come with
filters, and more can be purchased from a retailer or service
provider.
Now that your modem is installed and appropriate filters are
attached, you’re done. Enjoy using the X5.
The remainder of this manual contains information intended for
those users looking for expanded capabilities or for future
reference—for example, there are chapters on Advanced Setup
Options and System Administration. Refer to the Table of
Contents for guidance.
1.4 If You Need Help

Advanced Setup Options
In addition to its basic setup options, the X5 unit includes
options for specialized, or advanced, settings. If you are like
most users, you will not need these options. The X5 is designed
so that the basic setup settings are sufficient for most users.
This chapter is applicable only if you need to perform
sophisticated tasks.
2.1 How To Use the Advanced Options
All the Advanced Configuration settings are accessible from the
Advanced Setup page. Click its icon at the top of the X5’s main
interface page. (If you have exited from the X5 and have forgotten
how to establish communication with it, refer to page 10.)

Chapter 2: Advanced Setup Options 15
IMPORTANT:
Every time you make changes to an Advanced Setup page,
you must click the Save Changes button and then the Write
Settings to Flash and Reboot button. A Confirm page
displays; click the button to complete the process. If not, any
changes will be lost when you navigate to another page.
2.2 WAN Settings
The WAN Settings page contains information pertaining to your
Wide Area Network (WAN) ADSL setup and how you access the
Internet. From the Advanced Setup page, click the WAN
Settings button. A screen displays with several fields to fill in. For
each field or category, we have included a table for reference.
Note: Any settings entered in the Basic Setup page will be
reflected in the WAN Settings page.

16 X5 ADSL Modem User’s Manual

Chapter 2: Advanced Setup Options 17
Permanent VC (Virtual Circuit) Settings
Your service provider will supply the Permanent Virtual Circuit
(PVC) setting for your basic Internet connection. You can define
additional PVCs for services such as telephony or to connect to a
managed Virtual Private Network (VPN) if available in your area.
Consult your service provider.
Enabled? Enabled by default.
VPI Supplied by your service provider (reference
table appears on page 5).
VCI Supplied by your service provider (reference
table appears on page 5).
Static IP Address Most providers use dynamic IP addressing;
only providers using Bridged or Routed IP
Encapsulation can use static IP addresses. If
your provider has given you a static IP
address, enter it here.
Subnet Mask For static IP address users only (see above):
Enter the subnet mask of the static IP
address given to you by your service provider.
Virtual Circuits No. of virtual circuits that can be set up: 1-7.
Note: You must scroll down to the bottom of the page to reach
the Virtual Circuit field and select a number from the dropdown
list to identify a PVC. The number 0 is reserved for the Basic Setup
settings preconfigured for your provider. Be sure to click Save
Changes and then Write Settings to Flash and Reboot. Once
you have set up multiple PVCs, you can switch between them by
selecting a different number from the Virtual Circuit dropdown
list and clicking Save Changes and Writing Settings to Flash
and Reboot.
ATM
ATM, or Asynchronous Transfer Mode, allows you to change the
way in which your data is sent over the Internet.
ATM Service Category Default is UBR (Unspecified Bit Rate). CBR
(Constant Bit Rate) is optional. You can only
use CBR if you have arranged to do so with
your provider.
Bandwidth Default is 0(which equals UBR). Specifying
bandwidth is only possible with CBR.

18 X5 ADSL Modem User’s Manual
Encapsulation
The Encapsulation mode, like the VPI and VCI numbers, is
specified by your service provider (see Permanent VC Settings,
page 17).
Encapsulation This mode is supplied by your service provider
(reference table appears on page 5).
Bridge
The Bridge option is disabled by default. You should enable it
only if your service provider instructs you to.
IGMP (Internet Group Management Protocol)
IGMP is the Internet standard for IP multicasting, or broadcasting
a message to many recipients simultaneously. Your choices are
enabled or disabled; the default is disabled.
IMPORTANT:
Before enabling IGMP, navigate to the Advanced Setup
page, click Misc Configuration, select Enabled in the
IGMP Proxy dropdown list, and click Save Changes and
Write Settings to Flash and Reboot. If you don’t
perform this step first, enabling IGMP on this page will
not have any effect.
Default Gateway
Normally, you would not enter anything into the Default Gateway
field. You would do so only if you want to connect your modem to
the Internet via a different Gateway Router, or if your service
provider has instructed you to change it.
PPP (Point-to-Point Protocol)
PPP is the most widely used protocol for authenticating your
connection to the Internet. Should you change service providers,
you may need to change the data in these fields. Note: These
settings also appear on your Basic Settings page.

Chapter 2: Advanced Setup Options 19
User Name Supplied by your service provider.
Password Supplied by your service provider.

not want to be reconnected automatically if
the ADSL connection is terminated
unexpectedly.
*You must enter your PPP User Name and Password before making changes to
these fields; otherwise they will not take effect.
DHCP (Dynamic Host Configuration Protocol)
DHCP is disabled by default. Typically, you should not need to
change your DHCP setting. Do so only if your service provider
requests it.
DHCP client enable Check this box only if instructed to by your
service provider.
Host Name If necessary, supplied by your service
provider.
