Abstract
A method for adjusting a phase error includes a first device detecting a phase error at a timing interface of the first device. The first device modifying a DOCSIS timing protocol parameter based upon the detected phase error. The first device causing a modification of a second device's timestamp output in a manner based upon the detected phase error by the modification of the DOCSIS timing protocol parameter.
Claims4
A method comprising:
- (a) a first device detecting a phase error of a clock of the first device;
- (b) the first device modifying a Data-Over-Cable Service Interface Specifications (DOCSIS) timing protocol parameter based upon the detected phase error, the DOCSIS timing protocol parameter used to modify a clock output of a second device different than the first device;
- and
- (c) decreasing the magnitude of the modification of the DOCSIS timing protocol parameter over time after detecting the phase error.
