DSL-210 USB ADSL Modem User’s Guide

viii

If your ADSL service uses PPP (Point-to-Point Protocol) to establish the connection, you will install the

PPPoA or PPPoE driver. Using a PPP connection will be familiar to anyone who has used a conventional

dial-up analog modem for Internet connection. PPP is used to verify the user’s identity and to control

access to the network. A PPP session requires that a user name and password be given before gaining

access to network services. PPP sessions are ended when you log-off and terminate your connection to

the service provider’s network. Specifically, if your ADSL service uses the protocol defined by

RFC 2364

PPP over ATM Adaptation Layer 5

, or

RFC 2516

PPP over Ethernet,

install the PPPoA or PPPoE driver.

If the protocol used for your ADSL service is defined by

RFC 1483

Multiprotocol Encapsulation over

ATM Adaptation Layer 5 (Bridged Ethernet)

, then you will need to install the EoA driver. EoA driver users

may be required to manually configure your IP settings. Your DSL service provider will tell you if you

need to configure your PCs IP settings. The drivers are fundamentally different in the way they relate to

operating system of the computer. The computer/Modem relationship can be summarized as follows:

PPPoA or PPPoE driver

– To your computer, the Modem appears as a conventional dial-up modem

device. There is no actual dialing or any activity in the voice band frequencies on the telephone line, but

you must still provide a user name and password to log-on.

EoA driver

– To your computer, the Modem appears as an Ethernet device. Connection is automatic,

similar to a connection to an Ethernet device.

Encapsulation Method

It may be necessary to use an encapsulation method that is different from the default method. The

protocol used for your connection, and thus the driver you use will determine which encapsulation

method is used. If your DSL service provider does not specify, use the default encapsulation method.

Modulation Technique

It may be necessary to use a modulation method that is different from the default method. If your DSL

service provider does not specify, use the default modulation method called Multimode.
