    摘要： In some embodiments, a first computing device detects a loss of a connection to a first source of timing information that the first computing device and a second computing device use to maintain synchronization with a first clock and a second clock. The first computing device receives a second source of timing information from the second computing device. The second source of timing information is also being transmitted to a third computing device. The first computing device uses the second source of timing information to determine a first timestamp and determines a second timestamp from the first clock. The first computing device uses the first timestamp and the second timestamp to adjust a rate of the first clock where the first clock is used to transmit the second source of timing information from the second computing device to the third computing device.

    摘要： Nodes, amplifiers, and taps for an improved hybrid fiber-coaxial (HFC) network and methods for managing signals in an improved HFC network are shown and disclosed. The method may include receiving, at a node, a downstream optical signal in a higher-frequency band and a lower-frequency band separated from the higher-frequency band. The method may additionally include amplifying, at the node, the lower-frequency band by a magnitude different than that of the higher-frequency band. The method may further include combining, at the node, the higher-frequency band and the lower-frequency band into an output signal after the lower-frequency band has been amplified.
