Preparing Network Connections
Ethernet is most similar to IEEE 802.3 10Base5. Both of these protocols specify a bus topology
network with a connecting cable between the end stations and the actual network medium. Both
protocols require a device that acts as an interface between the end stations (the EIP) and the actual
network medium (cable). The Ethernet specifications call this device a transceiver, and it is
connected to the station with a transceiver cable. The IEEE 802.3 specification refers to the same
type of device as a media attachment unit (MAU) and to the cable as an attachment unit interface
(AUI). Both transceiver cables and AUIs can connect to the EIP ports directly.
Transceivers are available from a variety of sources for thick-wire (10Base5), thin-wire (10Base2),
or unshielded twisted-pair cabling (10BaseT at 10 Mbps); Figure 2-13 shows examples of
transceivers and connection equipment. You can connect either Ethernet Version 1 or
Version 2/IEEE 802.3 interfaces; the EIP automatically supports both types.
