DS1 is a widely used standard in telecommunications in North America and Japan to transmit voice and data between devices. E-carrier is used in place of T-carrier outside North America, 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." ] ,
