PPPoE/PPPoA
Follow the instructions below to configure the Modem to use a PPPoE or PPPoA for the Internet connection. Make sure
you have all the necessary information before you configure the WAN connection.
To set up a PPPoE or PPPoA connection:
1.
If not already selected, click the
PPPoE/PPPoA
radio button in the WAN Settings section in the middle of the
window. PPPoE/PPPoA is selected by default if you are configuring the Modem for the first time.
2.
The settings under ATM VC Setting at the top of the window should not be changed unless you have been
instructed to change them. However, if you are instructed to change the
VPI
or
VCI
values, type in the values
assigned for your account. Leave the
Virtual Circuit
setting at the default (
Enabled
) value for now.
3.
Under the PPPoE/PPPoA heading, type the
User Name
and
Password
used for your ADSL account. A typical
User Name will be in the form
. The
Password
may be assigned to you by your ISP or you
may have selected it when you set up the account with your ISP. See the table below for more information
about the optional settings,
AC Name
and
Service Name
.
4.
Choose the
Connection Type
from the pull-down menu located under the User Name and Password entry
fields. This defines both the connection protocol and encapsulation method used for your ADSL service. The
available options are
PPPoA VC-Mux, PPPoA LLC
and
PPPoE LLC.
If you have not been provided specific
information for the Connection Type setting, leave the default setting.
5.
Leave the
MTU
value at the default setting (default =
1400
) unless you have specific reasons to change this
(see table below).
6.
Leave the
MRU
value at the default setting (default =
1492
) unless you have specific reasons to change this
(see table below).
7.
Leave the
Default Route
enabled if you want to use the Modem as the default route to the Internet for your
LAN. Whenever a computer on the LAN attempts to access the Internet, the Modem becomes the Internet
gateway to the computer. If you have an alternative route for Internet traffic you may disable this without
effecting the Modem’s connection.
8.
Typically the globally IP settings (i.e. IP address for the WAN interface) for a PPPoA or PPPoA connection
will use Dynamic IP assignment from the ISP. Some accounts may be assigned a specific global IP address. If
you have been give an IP address for you PPPoE/PPPoA connection, select the
Static IP
option from the
IP
Control
pull-down menu. This menu can be used to configure the WAN port as an Unnumbered IP interface.
(See table below for Unnumbered IP)

Most users will not need to change ATM settings. If this is the first time you are setting up the ADSL
connection it is recommended that you leave the
Service Category
settings at the default values until you have
established the connection. See the table on page 26 for a description of the parameters available for ATM
traffic shaping.
