1. Cisco Systems does not supply Category 5 UTP RJ-45 cables; these cables are
available commercially.
2. AWG = American Wire Gauge. This gauge is specified by the EIA/TIA-568
standard.
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.
