  • Patent number: 8208573
    Abstract: A method and apparatus for performing trellis coded modulation of signals for transmission on a TDMA channel of a cable network, such as a DOCSIS cable network, is provided. In an embodiment, an upstream modulator portion of a cable modem receives burst data, selectively encodes the burst data for trellis coded modulation to generate encoded symbols, and modulates the encoded symbols for selective transmission over a time division multiple access (TDMA) channel or a synchronous code division multiple access (S-CDMA) channel of the cable network.

  • Publication number: 20110286330
    Abstract: A system and method is presented that uses hardware at a central node to determine if bandwidth being provided to a remote node in accordance with an unsolicited grant service (UGS) flow requires adjustment. In one embodiment, the hardware performs this function by comparing information in two consecutively-received UGS extended headers from the same remote device. If the information in the current and previous UGS extended headers differ, then an indication is provided to software of the central node that the bandwidth being provided to the remote node requires adjustment.

  • Patent number: 7379472
    Abstract: A system and method is presented to utilize hardware instead of software to compare for bandwidth request changes between two consecutively received unsolicited grant service (UGS) extended headers for the same service identifier (SID), obtains significant savings in CPU cycles for the CMTS software. The system determines whether adequate bandwidth is being provided from a cable modem termination system to a data provider during a unsolicited grant service flow. The system includes a means for receiving a current voice packet in the unsolicited grant service flow at the cable modem termination system from the data provider, where the current voice packet comprises a unsolicited grant service extended header. The system further includes means for comparing the current unsolicited grant service extended header with a previous unsolicited grant service extended header.
