What is 10 Base-T?
10Base-T --- standard configuration that allows construction of 10 Mbps ethernet LANs over unshielded twisted-pair wire.
Under 10 Base-T, workstations are cabled using twisted-pair wire to medium access units (MAUs). Each MAU normally has a built-in attachment interface unit (AIU) that can be cabled to a coaxial transceiver attached to a coaxial cable. Thus, workstations can be configured in a star topology and cabled to a bus structured backbone cable that serves to interconnect MAUs.
