  • Patent number: 6698022
    Abstract: A method for employing timestamps received by a media access controller (MAC) of a cable modem from a cable modem termination system (CMTS) to schedule upstream transmissions of the cable modem. A plurality of adjustment values, at least one of which is calculated using a least-square estimation algorithm, are used to adjust a local clock counter of the cable modem MAC. The local clock counter of the MAC is adjusted by one count for every number of cycles equal to a first adjustment value. The local clock counter of the MAC is further adjusted by a number of counts equal to a second adjustment value each time a corrected timestamp is calculated.
