Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. DS1 is a widely used standard in telecommunications in the United States and Japan to transmit voice and data between devices. E-carrier is used in place of T-carrier outside the United States, Japan, and South Korea. DS1 is the logical bit pattern used over a physical T1 line; however, the terms "DS1" and "T1" are often used interchangeably.
