Reference Manual for the Model DM602 ADSL Modem
Preparing Your Computer 3-9
Verifying the Readiness of Your DSL Internet Account
For access to the Internet, you need to contract with an Internet service provider (ISP) for a
single-user Internet access account using a DSL modem.
For a single-user Internet account, your ISP supplies TCP/IP configuration information. With a
typical account, much of the configuration information is dynamically assigned when your
computer is first booted up while connected to the ISP, and you will not need to know that dynamic
information.
Are Login Protocols Used?
Some ISPs require login protocol which requires you to enter a login name and password in order
to access the Internet. If you run a program such as WinPOET or EnterNet to connect to your
Internet account, then your account uses PPP over Ethernet (PPPoE).
If login protocols are used, you can configure your modem to operate in router mode. After the
modem is configured, it will perform the login task when needed, and you will no longer need to
run the login program from your computer. It is not necessary to uninstall the login program.
If you prefer to run the software on your computer which performs the login, you can do so by
configuring the modem to operate in Modem Device Mode.
Is Your ISP Configuration for a Static IP Address?
More and more, ISPs are dynamically assigning configuration information. However, if your ISP
does not dynamically assign configuration information but instead gave you a fixed configuration,
your ISP should have given you the following basic information for your account:
• An IP address and subnet mask
• A gateway IP address, which is the address of the ISP’s router
• One or more domain name server (DNS) IP addresses
• Host name and domain suffix
For example, your account’s full server names may look like this:
mail.xxx.yyy.com
In this example, the domain suffix is xxx.yyy.com.
