Techopedia Explains T3 Line
T3 refers to the trunk line level 3, and is sometimes used interchangeably with DS3 (digital signal level 3). In practice, the DS3 signal is transmitted over a T3 physical line, consisting of a fiber optic cable or coaxial cable. The T3 lines, which are symmetrical and duplex, have equal speeds on both upload and download, and therefore allow simultaneous transmissions without clogging the data lines.
