UNCTIONALITY DESCRIPTION
This chapter explains the Dual 56K LAN Modem’s key functionality for users who
wish to gain a fuller understanding of the LAN Modem before attempting to
install and configure the unit. The following topics are covered:
■ LAN Side Connectivity: Installing an Ethernet Hub
■ Wan Side: The Two 56K Modems
■ Using the Modem Channels
■ Dial-in Functionality
■ Understanding Multilink PPP and Other Line Usage Options
■ The Virtual FAX Modem (Windows 95, 98, NT, and 2000)
■ Support for Virtual Private Networks (VPNs)
For a basic understanding of modems and networking, refer to the Networking
Primer in Appendix A.
LAN Side Connectivity:
Installing an Ethernet
Hub
On the Local Area Network (LAN) side of the Dual 56K LAN Modem, you can
connect up to four computers and/or printers directly to the unit’s built-in Ethernet
hub. This allows you to create a LAN and enable file-, application-, and
printer-sharing among the attached devices. By connecting an external hub (not
included) to one of the four LAN ports, you can increase the number of users to a
total of 25. An example of a ten-workstation connection is shown in Figure 7.
