Configuration Guide
Purpose
This chapter will provide the configuration steps for the ADSL modem.
The ADSL modem automatically trains up to the ideal line speed. By
default, the ADSL modem is provisioned with rates of 8 Mbps
downstream and 640 Kbps upstream. The maximum operative rate is
determined by your DSL service provider. After establishing a connection
between your ADSL modem and your DSL service provider, you will
have an always-on connection. There are logical connections that should
be set up upon initial configuration, which establish the virtual channel for
different applications. To configure the logical connections, you must
provision ATM virtual connections.
On the ADSL modem, the ADSL physical interface is always ready to
send and receive network traffic. You may need to define an ATM virtual
connection (VC) when communicating across an ATM network for logical
connection setup. The ATM connection is identified by two indicators:
virtual path identifiers (VPI) and virtual circuit identifiers (VCI). Each
connection must have a unique pair of VPI and VCI settings. Check with
your service provider for details.
Select the ADSL Protocol
The US Robotics ADSL Ethernet Modem supports the following four
different ADSL protocols:
•
Multi-mode (default)
•
G.DMT (G.992.1)
•
G.Lite (G.992.2)
•
ANSI T 1.413 Issue 2
Log on to the ADSL Modem
In order to configure the ADSL modem, open a Web browser and enter
the default IP address of http://192.168.1.1. The default password is
12345. No User Name is required. You must use the default password
the first time you log in, but you should change the password for your
ADSL modem after the first login. Refer to the Change Password
section for details.
When using the multi-mode setting, the ADSL Ethernet modem will
attempt to automatically determine which protocol is being used. In most
cases, the default setting of Multi-mode should not be changed. This
setting should only be changed if your service provider has specified that
a specific protocol should be used. To use a different ADSL Protocol,
select the appropriate button and click OK.

One important characteristic of bridging is the number of bridge ports.
The ADSL modem has eight remote virtual ports on the ADSL interface
and one local port (Ethernet) on the user interface.
Configuring the Service Provider Settings
•
RFC1483 Bridged Mode (To be used as an Ethernet bridge)
•
RFC1483 Routed Mode
The ports on the ADSL interface are described as virtual because they
are associated with the ATM virtual connections that are configured on
the ADSL line. To establish a connection from any of the remote
destinations to the bridge port, PVCs must be configured end-to-end
through the network. Your DSL service provider will provide you with the
VPI/VCI values to use after you subscribe to the service.

(the network layer).
The ADSL Modem has eight remote virtual ports on the ADSL interface
and one local port (Ethernet) on the user interface.
The ports on the ADSL interface are described as virtual because they
are associated with the ATM virtual connections configured on the ADSL
line. To establish a connection from any of the remote destinations to the
ADSL modem port, PVCs must be configured end-to-end through the
network.

LAN Settings
The US Robotics ADSL Ethernet Modem has an integrated network
processor, which means it supports network features such as routing,
NAPT, DHCP, and DNS services. When configuring the modem for
routing, the following settings may need to be configured: Management
IP, NAPT, DHCP/DNS, and Routing Table. To access these settings,
click LAN Settings. These options will be shown at the bottom of the
Setup Menu. The configuration steps for these options are below.
Management IP
The Management IP address is the address of the inside Local Area
Network (LAN). This is a private address that is only accessible to the
computers that are connected to the US Robotics ADSL Ethernet
Modem. When packets are sent outside the network of the US Robotics
ADSL Ethernet Modem, the IP address gets converted to a globally
accessible IP address, or a WAN IP. The Subnet Mask is applied to an
IP address in order to mask a portion of the address. This will distinguish
the network ID from the host ID.
The NAPT feature converts IP addresses on a private network
(designated as inside or LAN) to global IP addresses that can forward
packets to another registered network (designated as "outside" or
"WAN"). It enables multiple PCs on the LAN to access the Internet for the
cost of one IP address. NAPT is a special case of NAT, where many IP
numbers are hidden behind a number of addresses. In contrast to the
original NAT, the number of connections is not limited to that number.
With NAPT, an almost arbitrary number of connections is multiplexed
using TCP port information. Enabling the NAPT inbound server will allow
WAN devices to access your LAN.
To set up the NAPT feature, you must select the appropriate Interface.
You must then select the Port number, Protocol (UDPor TCP), and the
Server IP Address for each port that you want to enable. Click OK to
save the settings.
To access the Management IP address configuration, click LAN
Settings and then click Management IP. To change the Management IP
Address and the Subnet Mask, enter the values that were provided by
your service provider and click OK. The default IP address is
192.168.1.1 and the default subnet mask is 255.255.255.0. Usually these
settings will not need to be changed.
Configuring NAPT

Configuring DHCP/DNS Service
increments of seconds. When you have completed the setup,
click OK to save the configuration.
Setting DNS Service
Most service providers will automatically assign the DNS Server
IP address by using Auto Discovery. Once DNS Relay is
enabled, Auto Discovery will be enabled by default. If your
service provider requires a static DNS entry to be set, Disable
must be selected for DNS Relay. You must then enter the DNS
Server IP address in the Manual Setting field. When you have
completed the setup, click OK to save the configuration.
Create a Routing Table
Each routing table entry comes with the following parameters:
Dynamic Host Configuration Protocol (DHCP) is the protocol that
is used to automatically assign an IP address to a client
computer. Domain Name Server (DNS) is the Internet protocol
for mapping host names, domain names, and aliases to IP
addresses.
Setting DHCP Service
When enabling NAPT or using the modem in PPPoA mode, the
DHCP server should be enabled. To enable the DHCP server,
click the Enable button. When the DHCP server is enabled, IP
addresses will automatically be assigned. This can be seen by
selecting System allocates address pool. When you have
completed the setup, click OK to save the configuration.
Parameters
Description
RIP on/off
Checked to enable RIP (Router Information
Protocol) function
Dest.
Network ID
The network ID of the destination IP address
Dest. Subnet
The subnet mask of the destination IP address
mask
Mask
The subnet mask of the destination subnet
Next Hop IP
The IP address of the neighbor/peer interface for
routing purpose
There are two ways to create a routing table. One is to enable RIP and
the system will create a routing table dynamically through the routing
information. The other is to disable RIP option and create a static routing
table manually. Once RIP is enabled, the routing table entries will
disappear. While the RIP is disabled, the user must create a routing table
for a specific routing path. RIP is enabled/disabled by selecting/deselecting RIP on/off.
If you need to assign the range for the beginning and end IP
addresses, select Assign address pool range. You will then
need to enter the Beginning IP address, the End IP address, and
the Max Lease Time. The Max Lease Time must be entered in
