WAN Connection The 56K LAN Modem allows up to 25 users to connect to a WAN using one
analog connection to a single location.
One High Speed
Connection
The WAN connection may be utilized by a single user to connect to a remote site
such as a corporate LAN, as shown in Figure 5.
Figure 5 Single User Connecting to a Remote Site
Sharing the Connection Once the call is established, up to four users may share the single connection
created by the call over the LAN Modem’s four-port built in hub. Or, up to 25 users
may share this connection over an external hub. Figure 6 shows two users on the
LAN accessing the Internet through the same Internet provider and over the same
connection. If you desire, you may also restrict access to certain users. Note that
speed may be affected with multiple users downloading simultaneously.
Figure 6 Shared Connection to a Remote Site
Your 56K LAN Modem is capable of supporting WAN access for up to 25 users.
However, for improved performance it is recommended that no more than four
users attempt to share a single connection at one time.
