    摘要： Aspects of a method and apparatus for band separation for multiband communication systems are provided. One or more circuits for use in a transceiver may comprise a triplexer and a leakage processing module. The triplexer may comprise a multiband port, a Multimedia Over Coaxial Alliance (MoCA) port, a television upstream port, and a television downstream port. The leakage processing module may comprise a television downstream input port, a cable television downstream output port, a MoCA port, and a cable television upstream port. The leakage processing module may be operable to (1) process a MoCA signal to generate a first compensation signal; (2) process a cable upstream signal to generate a second compensation signal; (3) process a filtered signal based at least in part on the first and second compensation signals; and (4) output the processed filtered signal via the cable television downstream output port of said leakage processing module.

    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： Apparatus, system and method for synchronizing one or more clocks across a communication link. A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side. The slave clock may correlate received signals with a representation of the expected synchronization signal to produce a correlation sample sequence at a first sample rate which is related as n times the slave clock rate. The synchronization signal receipt time indicated by the correlation sample sequence may be refined by interpolating the correlation sample sequence around a best correlation sample to locate a best interpolation at an interpolation resolution smaller than the sample resolution. The best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output. The synchronization signal receipt time thus determined is compared to the expected time based upon the slave clock, which is adjusted until the times match. After initialization, all slave clock errors are preferably accumulated to prevent long-term slip between the slave and master clocks. Formerly independent master and slave clocks synchronized across the communication link constitute a noncommon clock which may be compared on each side of the link to secondary independent clocks, and the secondary independent clocks may then be separately synchronized by adjusting one to have the same difference from its local noncommon clock as the secondary clock on the other side of the link has from its local noncommon clock.
