Figure 47 shows a UTP cable with an RJ45 connector. For a 10BASE-T link
between a hub and a Medium Attachment Unit (MAU) or Network Interface
Controller (NIC), the cable is wired straight-through. That is, an RJ45
receptacle at the hub would wire pin-to-pin to the RJ45 receptacle at the
MAU, as shown in Figure 48.
