T-carrier

A digital transmission service from a common carrier. Introduced by AT&T in 1983 as a voice service, its use for data has grown steadily. T1 and T3 lines are widely used to create point-to-point private data networks. T-carrier lines use four wire cables. One pair is used to transmit; the other to receive.
