Abstract: The present disclosure is directed to time stamp detection using a cable modem and to a control apparatus, control device and control method for detecting timestamps in various signals such as orthogonal frequency division multiplexing (OFDM) signals. The control apparatus comprising processing circuitry being configured to obtain information a channel frequency response of the multi-path channel, the channel frequency response being based on a signal comprising a sequence of symbols. The processing circuitry is configured to transform the channel frequency response into a channel impulse response. The processing circuitry is configured to identify a peak in the channel impulse response. The processing circuitry is configured to determine a timestamp offset time between the peak in the channel impulse response and a trigger time indicative of a beginning of a symbol in the signal. The processing circuitry is configured to synchronize the device clock based on the timestamp offset time.

Abstract: A network infrastructure combining data over cable service interface specification (DOCSIS) cable modem management and 10 Gb passive optical network XGPON networking technology. The DOCSIS equipment controls restrict the XGPON to physical layer (layer 1) while the DOCSIS equipment operate at a data link layer and above.
