4. Setting up your CPE
This section will guide you through your CPE’s configuration. The CPE is shipped with a standard default
bridge configuration; for most users, you may want to change the CPE from a bridge to a router.
4.1 Log into your CPE
To configure your CPE, open your web browser. You may get an error message at this point; this is normal.
Don’t panic. Continue following these directions. Type the default IP address (192.168.1.1) Press the
Enter key and the following screen, shown in Figure 1 will appear. The default user name is Admin (case
sensitive) and the password is Admin (case sensitive).
Note: Before setting up your CPE, make sure you have followed the quick start guide. You should have
your computers configured for DHCP mode and have proxies disabled on your browser. Also if you access
the router, and instead of getting a login screen, the browser instead displays a login redirection screen, you
should check your browser's setting, and verify that JavaScript support is enabled. Also, if you do not get
the screen shown in Figure 1, you may need to delete your temporary Internet files (basically flush the
cached web pages).
Figure 1 (Log-in Screen)
4.2 Home screen
The first screen (Figure 2) that appears (after the log in screen) is the Home screen. From this screen the
user can setup the modem (configure the LAN and WAN connection(s), configure the advanced
configuration options within the modem (security, routing, and filtering), access tools that are helpful for
debug purposes, obtain the status of the modem, and view the extensive online help.
The basic layout of the Home page consists of a page selection list across the top of the browser window.
The footer displays CPE status, connection information, and other useful information. The center display is
where most of the configuration will take place.

Figure 2 (Home page)
4.3 Setup
To setup your CPE with a basic configuration, from the Home page, select Setup. Figure 3 illustrates the
setup page. The page is broken into two subsections the WAN configuration and the LAN configuration.
Before configuring the router, there are several concepts that you should be familiar with on how your new
router works. Please take a moment to familiarize yourself with these concepts, as it should make the
configuration much easier.
Figure 3 (Setup page)
4.3.1 Wide Area Network connection
On the other side of the router is where your Wide Area Network (WAN) connection; also referred to as a
broadband connection. This WAN connection is different for every WAN supplier. Most of the
configuration you will perform will be in this area. Local Area Network Connection(s)

AAM6020VI-T4 User Manual
14 14
4.3.2 Local Area Network connection
On one side of your router, you have your own Local Area network (LAN) connections. This is where you
plug in your local computers to the router. The router is normally configured to automatically provide all
the PC's on your network with Internet addresses.
4.4 Configuring the WAN
Before the CPE will pass any data between the LAN interface(s) and the WAN interface, the WAN side of
the modem must be configured. Depending upon your DSL service provider or your ISP, you will need
some (or all) of the information outlined below before you can properly configure the WAN:
• Your DSL line VPI and VCI
• Your DSL encapsulation type and multiplexing
• Your DSL training mode
For PPPoA or PPPoE users, you also need these values from your ISP:
• Your username and password
For RFC 1483 users, you may need these values from your ISP:
• Your DSL fixed Internet IP address
• Your Subnet Mask
• Your Default CPE
• Your primary DNS IP address
Since multiple users can use the CPE, the CPE can simultaneously support multiple connection types;
hence, the user must set up different profiles for each connection. The CPE supports the following
protocols:
• DHCP
• RFC 2364 PPPoA
• RFC2516 PPPoE
• Static
• Bridged
• CLIP
.
4.4.1 New Connection
A new connection is basically a virtual connection. Your CPE can support up to 8 unique (with different
vpi/vci) virtual connections. If you have multiple different virtual connections, you may need to utilize the
static and dynamic routing capabilities of the modem to pass data correctly.
4.4.1.1 Bridged CPE profile and Connection
A pure bridged connection does not assign and IP address to the WAN interface. NAT and firewall rules
are not enabled. This connection method makes the router act as a hub, and just passes packets across the
WAN interface to the LAN interface.
To configure the CPE as a bridge, from the Home page, click on Setup and then click on New Connection.
The default PPPoE connection setup is displayed. At the Type field select Bridge and the Bridge
connection setup page is displayed (see Figure 4). Give your Bridge connection a unique name; the name
must not have spaces and cannot begin with numbers. In this case the unique name is called bridge1.
Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select the VPI
and VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL service
provider is using 0,35. Also select the quality of service (QOS); leave the default value if you are unsure or
the ISP did not provide this information.

Figure 4 (Bridge Connection Setup)
To complete the connection you must now click the apply button. The apply button will temporarily save
this connection. To make the change permanent you need to click on Tools (at the top of the page) and
select System Commands. At the system commands page, click on Save All.
4.4.1.2 PPPoA Connection Setup
PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells which are
carried over the DSL line. PPP or Point-to-Point protocol is a method of establishing a network connection
/ session between network hosts. It usually provides a mechanism of authenticating users. LLC and VC are
two different methods of encapsulating the PPP packet. Contact your ISP to make sure which encapsulation
is being supported.
By selecting PPPoA, you are forcing your CPE to terminate the PPPoA connection. The advantage is that
the PPPoA termination is done within the CPE and not on your PC; this frees up your PC resources and
allows multiple users to utilize the PPPoA connection.
To configure the CPE for PPPoA, click on Setup and then click on New Connection. The default PPPoE
connection setup is displayed. At the Type field select PPPoA and the PPPoA connection setup page is
displayed; figure 5 illustrates a typical PPPoA configuration. Give your PPPoA connection a unique name;
the name must not have spaces and cannot begin with numbers. In this case the unique name is called
PPPOA1. Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select
the VPI and VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL
service provider is using 0,40. Also select the quality of service (QOS); leave the default value if you are
unsure or the ISP did not provide this information.
Following is a description of the different options:
a. Username: The username for the PPPoA access; this is provided by your DSL service
provider or your ISP.
b. Password: The password for the PPPoA access; this is provided by your DSL service provider
or your ISP.
c. On-Demand: Enables on-demand mode. The connection will disconnect if no activity is
detected after the specified idle timeout value.
d. Idle Timeout: Specifies that PPPoA connection should disconnect if the link has no activity
detected for n seconds. This field is used in conjunction with the On-Demand feature. To
ensure that the link is always active, enter a 0 in this field.

AAM6020VI-T4 User Manual
16 16
e. Keep Alive: When on-demand option is not enable, this value specifies the time to wait
without being connected to your provider before terminating the connection. To ensure that
the link is always active, enter a 0 in this field.
f. Set Route: Specify this connection as the default-route.
g. MRU: Maximum Receive Unit the DSL connection can receive. It is a negotiated value that
asks the provider to send packets of no more than n bytes. The maximum specified value is
1500 although some DSL/ISP providers require a larger value. The minimum MRU value is
128.
h. Debug: Enables PPPoA connection debugging facilities. Debugging is talked about later.
Figure 5 (PPPoA Connection Setup)
To complete the connection you must now click the apply button. The apply button will temporarily save
this connection. To make the change permanent you need to click on Tools (at the top of the page) and
select System Commands. At the system commands page, click on Save All.
4.4.1.3 PPPoE Connection Setup
PPPoE is also known as RFC 2516. It is a method of encapsulating PPP packets over Ethernet. PPP or
Point-to-Point protocol is a method of establishing a network connection/session between network hosts. It
usually provides a mechanism of authenticating users.
To configure the CPE for PPPoE, click on Setup and then click on New Connection. The default PPPoE
connection setup is displayed. At the Type field select PPPoE and the PPPoE connection setup page is
displayed; figure 6 illustrates a typical PPPoE configuration. Give your PPPoE connection a unique name;
the name must not have spaces and cannot begin with numbers. In this case the unique name is called
PPPOE1. Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select
the VPI and VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL
service provider is using 0,30. Also select the quality of service (QOS); leave the default value if you are
unsure or the ISP did not provide this information.

PPPoE connection. This feature will force all TCP traffic to conform with PPP MRU by
changing TCP Maximum Segment Size to PPP MRU.
i. Debug: Enables PPPoE connection debugging facilities. Debugging is talked about later.

this connection. To make the change permanent you need to click on Tools (at the top of the page) and
select System Commands. At the system commands page, click on Save All.
4.4.1.4 DHCP Connection Setup
Dynamic Host Configuration Protocol (DHCP) allows the CPE to automatically obtain the IP address from
the server. This option is commonly used in situations where IP is dynamically assigned and is not known
prior to assignment.
To configure the CPE for a DHCP connection, click on Setup and then click on New Connection. The
default DHCP connection setup is displayed. At the Type field select DHCP and the DHCP connection

setup page is displayed; figure 7 illustrates a typical DHCP configuration. Give your DHCP connection a
unique name; the name must not have spaces and cannot begin with numbers. In this case the unique name
is called DHCP1. Select the encapsulation type (LLC or VC); if you are not sure just use the default mode.
Select the VPI and VCI settings; your DSL service provider or your ISP will supply these; in this case the
DSL service provider is using 0,35. Also select the quality of service (QOS); leave the default value if you
are unsure or the ISP did not provide this information.
If your DSL line is connected and your DSL/IPS provider is supporting DHCP, you can click the renew
button and the CPE will retrieve an IP address, Subnet mask, and CPE address. At anytime, you can renew
the DHCP address by clicking on the renew button; in most cases you will never have to use this button.

this connection. To make the change permanent you need to click on Tools (at the top of the page) and
select System Commands. At the system commands page, click on Save All.
4.4.1.5 Static Connection Setup
Static is used whenever a known static IP is assigned. The accompanying information such as the Subnet
mask and the CPE should also be specified. Up to three Domain Name Server (DNS) addresses can also be
specified. These servers would enable you to have access to other web servers. Valid IP addresses range is
from 0.0.0.0 to 255.255.255.255.
To configure the CPE for a Static connection, click on Setup and then click on New Connection. The
default Static connection setup is displayed. At the Type field select Static and the Static connection setup
page is displayed; figure 8 illustrates a typical Static configuration. Give your Static connection a unique
name; the name must not have spaces and cannot begin with numbers. In this case the unique name is
called STATIC1. Select the encapsulation type (LLC or VC); if you are not sure just use the default mode.
Select the VPI and VCI settings; your DSL service provider or your ISP will supply these; in this case the
DSL service provider is using 0,35. Also select the quality of service (QOS); leave the default value if you
are unsure or the ISP did not provide this information. You can also enable Network Address Translation
(NAT) and the Firewall options. If you are unsure, leave these in the default mode.
Based upon the information your DSL/ISP provided, enter your assigned IP address, Subnet Mask, Default
CPE (if provided), and Domain Name Services (DNS) values (if provided). For the static configuration,

you can also select a bridge connection or a routed connection. Since static IP address is typically used to
host WEB servers, you may want to use a bridge connection.

To complete the connection you must now click the apply button. The apply button will temporarily save
this connection. To make the change permanent you need to click on Tools (at the top of the page) and
select System Commands. At the system commands page, click on Save All.
4.4.2 Modify an Existing Connection
To modify an existing connection, from the Home screen, click setup and then click the connection you
want to modify. The connections are listed as Connection 1 through Connection 8
As a note, if you delete the connection, to make the change permanent you need to click on Tools (at the
top of the page) and select System Commands. At the system commands page, click on Save All.
4.4.3 Modem setup
To configure the DSL modulation type, go to the Home screen, Click setup. Under WAN Setup, select
Modem Setup. This will bring up the modem setup screen. Leave the default value if you are unsure or the
DSL/ISP did not provide this information. For most all cases, this screen should not be modified.
The apply button will temporarily save this connection. To make the change permanent you need to click
on Tools (at the top of the page) and select System Commands. At the system commands page, click on
Save All.
4.5 Configuring the LAN
By default, your CPE has DHCP server (LAN side) enabled. If you already have a DHCP server running on
your network, you must disable one of the two DHCP servers; if you plug a second DHCP server into the
network, you will experience network errors and the network will not function normally.
4.5.1 Enable/Disable DHCP
To enable or disable DHCP go to the Home screen, Click setup. Under LAN Setup, select DHCP
Configuration. This will bring up the screen shown in Figure 9.

AAM6020VI-T4 User Manual

The Start IP Address is where the DHCP server starts issuing IP addresses and the End IP Address is where
the DHCP server stops issuing IP addresses.
The Lease Time is the amount of time a network user will be allowed connection to the Router with their
current dynamic IP address. The amount of time is in units of minutes; the default value is 3600 sec (60
minutes).
Note: If you change the start or end values, make sure the values are still within the same subnet as the
CPEs IP address.
Figure 9 (DHCP Server configuration)
In addition to the DHCP server feature, the CPE supports the DHCP relay function. When the CPE is
configured as DHCP server, it assigns the IP addresses to the LAN clients. When the CPE is configured as
DHCP relay, it is responsible for forwarding the requests and responses negotiating between the DHCP
clients and the server. See figure 10.
