  • Patent number: 7433460
    Abstract: A method of controlling link transmission parameters of a communication flow in a network caches one or more network parameters at the end of a first communication flow for an elapsed time, and adjusts the network parameters for controlling link quality and transmit power of a next communication flow based on an uncertainty that is caused by caching for the elapsed time. The state of a communication channel during a previous communication flow (connection) is used to determine network parameters to use at a future communication flow. When a connection begins, and the network does not know the ideal settings to use, the network defines a specified, elapsed time duration over which the state of a previous connection no longer can be trusted, i.e., an uncertainty period. Network parameters are adjusted to account for uncertainty caused by the elapsed time.

  • Patent number: 6535602
    Abstract: The present invention relates to relates to electrical connectors, and in particular to a connector that replaces industry standard “punch down block” wiring devices to eliminate the need for rewiring when changing or re-routing multiple phone lines at a given location. The present invention provides for the connection of edge card connectors to punch down blocks or other wire terminating devices that are permanently connected to incoming and outgoing phone lines in a unique way by the use of jumpers that eliminate the need for rewiring when changing or re-routing multiple phone lines at a given location. A key advantage is that the invention makes the re-routing operation foolproof in that access to the permanently connected wiring is no longer necessary thereby eliminating the possibility of negatively affecting the integrity of the phone network by attempting to customize the wiring connections.
