Modem and the ADSL connection.
Software Uninstall
It provides detailed steps for removing the USB ADSL modem software from
the PC.
Overview
About ADSL
Asymmetric Digital Subscriber Line (ADSL) technology provides high-speed data
access across regular phone lines (copper wires) by making use of previously
unused frequency bandwidth above the voice band. By placing the ADSL signal
above the frequency of the voice signal, ADSL service is able to coexist on the
same line with your telephone service. ADSL is asymmetric in the sense that it
provides a higher data rate in the downstream (receive) direction than in the
upstream (transmit) direction. Asymmetric operation is ideal for typical home and
small office use where files and information are downloaded more frequently than
uploaded.
The USB ADSL Modem is capable of supporting the following DSL standards:
ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), ITU G.992.2 (G.lite), and ITU G.992
Annexes A, B, and C as applicable.
Protocol and Device Driver Selection
The USB ADSL Modem can be easily connected to a USB port on the PC via a
standard USB cable. The USB ADSL Modem is fully software upgradeable so
that new features and updates may be added by simply loading a new version of
the device driver onto your PC.
ADSL modems employ ATM (Asynchronous Transfer Mode) framing. ATM is a
protocol that divides packets into small fixed sized cells for rapid transmission
over high-speed networks. The ATM protocol allows various types of traffic (e.g.
data, voice, and video) to be securely and efficiently carried over the same
network. ATM is being widely deployed by telecommunications carriers in their
backbone networks. Two type of ATM connections are possible, PVC (Permanent
Virtual Circuit) and SVC (Switched Virtual Circuit).
Several different protocols are used on top of ATM. The protocol required in your
configuration depends on the equipment deployed by your DSL service provider.
There are several possibilities:
1. Point to Point Protocol (PPP) Over ATM (RFC 2364)
PPP provides session setup, user authentication (login), and encapsulation
for upper layer protocols such as IP (Internet Protocol). The use of PPP
makes the modem appear as a dial modem to the operating system. Dial-Up
Networking is used to establish a connection. The WAN (Wide Area Network)
driver and the ATM driver support PPP.
2. Bridged/Routed Ethernet/IP over ATM (RFC 1483)
This protocol makes the modem appear as a local area network (LAN) device
to the operating system.
3. RFC 1577
This is a local area network protocol which supports IP to ATM and ATM to IP
address mapping.
4. Point-to-Point Protocol (PPP) Over Ethernet (RFC 2516)
This protocol, commonly called PPPoE, allows multiple computer users on an
Ethernet to share a common DSL connection to the Internet. The WAN, LAN,
and ATM drivers support PPPoE. Refer to
for more details.
Three types of device drivers are provided for the ADSL USB modem, WAN,
LAN, and ATM.
Note: All three drivers support ATM protocol. In addition, the ATM driver works
with ATM services that are available in recent Windows operating systems.
The proper choice of driver depends on the combination of Windows
operating system and protocol.
1. WAN driver
This driver causes the modem to resemble a dial-up modem. Call
establishment is performed through Dial-Up Networking. This driver supports
RFC 2364 and 2516 with PVC connections. It can be used with Windows 98,
Windows 98 SE, Windows 2000, Windows Me, and Windows XP.
2. LAN driver
This driver makes the modem appear as a LAN or Ethernet device.
Connection establishment is automatic. This driver supports RFC 1483 with
PVC connections. Additionally, PPPoE is supported via third-party software.
This driver can be used with Windows 98, Windows 98 SE, Windows 2000,
Windows Me, and Windows XP.
3. ATM driver
This driver works in conjunction with ATM services provided by Windows.
RFC 1577, PPPoE, and RFC 2364 are supported. The ATM driver uses Dial-
Up Networking to create a PVC or SVC connection to establish a PPP (RFC
2364) connection. This driver can be used with Windows 98 SE, Windows
2000, Windows Me, and Windows XP.
Note: PPPoE support is provided for Windows XP only.
