A single PC with integrated Ethernet port or Ethernet Personal Computer Network
Interface Card (PC-NIC) can be connected to the ADSL modem (see figure 20).
The connection must be made with a straight-through cable (see figure 21) since a
PC is equipped with an Ethernet interface of type Medium Dependent Interface
(MDI).

To connect multiple PCs to an Ethernet interface, a hub must be installed first
(see figure 22).
The connection of the hub to the ADSL modem must be made with a crossover
cable (see figure 23), since the hub is equipped with an Ethernet interface of type
MDI-X.
