    摘要： A transceiver system may be configured to provide tunable bandwidths. The transceiver may comprise a signal processing component and a filtering component, which may comprise a plurality of filters. The signal processing component may determine one or more adjustments that are applicable to one or both of a first filter that is configured for filtering signals corresponding to a first frequency band associated with a first stream, and a second filter that is configured for filtering signals corresponding to a second frequency band associated with a second stream. The one or more adjustments may correspond to modifications in one or both of the first frequency band and the second frequency band. The one or more adjustments may be communicated to the filtering component, which may apply the adjustments to one or more of the plurality of filters.

    摘要： A network device (e.g., a cable modem) may support a normal mode of operation and a sleep mode of operation. While in the normal mode, a PHY of the network device may process a received signal to recover MPEG-TS packets, and convey the MPEG-TS packets to other components of the network device for further processing. While in the sleep mode, the PHY may process received MPEG-TS packets having a particular packet identifier and drop received MPEG-TS packets not having the particular packet identifier. The PHY may control transitions between the normal mode and the sleep mode in response to received signals having particular physical layer characteristics. The PHY may demodulate a received signal to recover an MPEG-TS packet; descramble portions of the MPEG-TS packet; inspect portions of the MPEG-TS packet; and control a mode of operation of the network device based on the contents of the MPEG transport stream.

    摘要： A network device may be operable to receive an indication from a cable modem termination system (CMTS) that media access control (MAC) management messages will be transmitted by the CMTS at fixed intervals. Subsequent to receiving the indication, the network device may be operable to power down one or more components of the network device and set a sleep timer to a value equal to an integer multiple of the fixed interval minus a transition period. The network device may power up the one or more components of the network device upon expiration of the sleep timer. The network device may power up the one or more components of the network device upon an amount of traffic in a buffer of the network device reaching a threshold.

    摘要： A CMTS may receive a request that a network device be permitted to enter a power-saving mode of operation. In response, the CMTS may enter a power-saving mode of operation wherein MAC management messages, transmission opportunities for the sleeping network device, and/or contention periods on one or more channels occur at independently determinable intervals. The CMTS may then transmit a message granting the network device permission to enter the power-saving mode of operation. The CMTS may start a sleep timer upon transmitting the MAC management message and may deregister the network device if no communication is received from the network device prior to expiration of the sleep timer. The CMTs may buffer traffic destined for the network device in a buffer of the CMTS while the network device is in the power-saving mode of operation, and may wake the network device upon the amount of buffered traffic reaching a threshold.
