| serial clock transmit external The timing signal that data terminal equipment (DTE) echoes to data communications equipment (DCE) to maintain clocking. Serial clock transmit external (SCTE) is designed to compensate for clock phase shift on long cables. When the DCE device uses SCTE instead of its internal clock to sample data from the DTE, it is better able to sample the data without error even if there is a phase shift in the cable. See also phase shift. |
