Chapter 1: Overview
4 GlobeSpan, Inc. Proprietary – Use Pursuant to NDA
address mapping.
Three types of device drivers are provided for the GlobeSpan ADSL USB modem, WAN,
LAN, and ATM. Note that 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 with PVC connections. It can be used with Windows 98, Windows 98 SE and
Windows 2000.
2. LAN (RFC 1483) 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. It can be used with Windows 98, Windows 98 SE, and Windows
2000.
3. ATM driver – this driver works in conjunction with ATM services provided by
Windows. Both RFC 1577 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 and Windows 2000.
