-====== 3Com - 3c108 AUI transceiver (Medium Attachment Unit, MAU) ======
-===== Overview =====
-{{ networking:3c108-a.jpg?100|}}[[https://en.wikipedia.org/wiki/Attachment_Unit_Interface|AUI]] to thick ethernet transceiver designed to connect to network cards with an AUI 15 pin D socket. This interfaced to a 50 Ohm coaxial cable via N-type coax connectors and provided a connection "Drop".
-The correct name for this is a ''Medium Attachment Unit''.
-{{networking:3com-isa-aui.jpg?100 |3Com ISA network card with AUI port.}}
-The transceivers are powered from a source in the network card, the tx and rx connections are over a twisted pair.
-The card on the right is an old 3Com one, it has from bottom to top, a thin ethernet BNC socket ([[https://en.wikipedia.org/wiki/10BASE2|10Base-2]]), and [[https://en.wikipedia.org/wiki/Attachment_Unit_Interface|AUI port]] for connecting to the 3C108 transceiver (Using a 15pin D plug to 15pin D socket, 3 sets of twisted pairs, Tx, Rx and power) and at the top, a [[https://en.wikipedia.org/wiki/Ethernet_over_twisted_pair|10Base-T]] RJ45 connector.
