  • Patent number: 11483087
    Abstract: Systems and methods for clock synchronization are disclosed in which a primary node generates special physical layer clock sync symbols from the output of a reference clock and inserts the clock sync symbols within a symbol stream to one or more secondary nodes. Upon receiving a symbol stream, a secondary node can extract the clock sync symbols from the stream to synchronize its local clock with the reference clock of the primary node. In particular, the clock sync symbols can be inserted into the symbol stream at any arbitrary symbol location, e.g., even between consecutive symbols of a symbol encoded data frame. The clock sync symbols can also replace some control symbols in the symbol stream, such as idle or comma symbols. Accordingly, the clock sync symbols can be inserted into a symbol stream at fixed intervals, irregular intervals, or at any arbitrary time for high resolution clock synchronization.

  • Patent number: 9083785
    Abstract: A discrete multi-tone (DMT) transceiver communicates tones across a subscriber line. Vectoring is employed in an effort to reduce the effects of crosstalk. However, for some tones, such as tones significantly affected by radio frequency interference (RFI) or other forms of alien noise, vectoring may actually introduce distortions such that the vectoring degrades rather than improves overall signal quality. Control logic of the DMT transceiver is configured to sense when tones are affected by significant levels of alien noise and to exclude such tones from vectoring, thereby improving signal quality for such tones. The control logic also may lower the constellation densities of such tones in order to accommodate the vectoring exclusions applied to such tones.

  • Patent number: 8930545
    Abstract: Handling of multiple connections during NAT traversal for a node behind a symmetric NAT is disclosed. The likelihood of connection failure during symmetric NAT traversal may be reduced by serializing critical time windows after port prediction. Once a connection request has been sent for a first connection, port prediction for a subsequent connection may be delayed until a connectivity check has begun for the first connection. This process may be repeated to handle NAT traversal for multiple simultaneous connections to different nodes.
