Connecting an
External Hub to the
Dual 56K LAN Modem
Once you have finished configuring the Dual 56K LAN Modem, you can connect
up to three additional computers, or a combination of an external Ethernet hub
and computers to increase the number of users for WAN access to 25.
Figure 35 shows the more common scenario of an additional 8-port hub for a
10-user, shared WAN connection.
Figure 35
10-User Shared WAN Connection Using an 8-Port Ethernet Hub
Before You Begin
To create a shared WAN connection for more than four users on the Dual 56K LAN
Modem, you will need the following:
■
A 10BASE-T Ethernet hub, such as the OfficeConnect Ethernet Hub 8
■
A 10BASE-T Ethernet cable (two RJ-45 to RJ-45 connector ends, not provided)
■
A 10BASE-T Ethernet cable for each additional workstation
If the hub you are using does not have an MDI/MDIX switch, you will have to use a
crossover cable.
