Cable Specifications for 10-Mbps 10BASE-T
The Ethernet specifications call the 4E device a transceiver, and it is connected to the station with a
transceiver cable. The 4E port adapter is not an end station. The IEEE 802.3 specifications refer to
the same type of device as a media attachment unit (MAU) and to the cable as an attachment unit
interface (AUI). Only transceiver cables can connect to the 4E ports directly.
