UNCTIONALITY
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.
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.
