摘要： Systems and methods for adaptively adjusting a slew rate of a dejitter buffer in a remote device in a distributed access architecture. The slew rate may be adjusted based on measurements of a fullness state of a buffer made over time. The measurements may be used to calculate a frequency offset value between the rate at which data leaves the buffer relative to the rate at which data enters the buffer and/or used to calculate a current working depth of the buffer. The adaptive slew rate adjustments may be based on the frequency offset value and/or the current working depth.

摘要： Systems and methods for providing DOCSIS services and at least one additional services to a cable modem by a Remote MACPHY device (RMD). The additional service is provided using a core configured to have an associated timing lock to the RMD, where the RMD is configured to receive information indicating the absence of the timing lock and use the information to disable the additional service while selectively maintaining the DOCSIS services.

摘要： Systems and methods for providing timing information from a R-MACHPHY device to a video core while the R-MACPHY device receives video data from the video core while operating in asynchronous mode. In some embodiments, the R-MACPHY device may alternately and selectively configure its mode of operation to alternate between synchronous mode and asynchronous mode, and provide the timing information to the video core when it switches to asynchronous mode.

摘要： 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.

摘要： Using timing delays and values associated with plant information between a CMTS, R-PHY device or a remote MACPHY device and user devices on a network to determine the distance between a head end device, for example a CMTS, R-PHY device or a remote MACPHY device and an end-user device such as cable modem in order to alert to a stolen, outdated, misplaced or otherwise at-risk end-user device.
