Abstract
A master clock reference signal may be provided to selected packet fiber nodes in order to synchronize the local clock reference signals generated at selected devices in a cable network. In this way, selected portions of the cable network may be synchronized to a common timing reference signal. Additionally, synchronized timestamp information may also be provided to selected network devices in order to achieve synchronization of timestamps across a selected portion of the cable network.
