  • Fault recovery system and method for inverse multiplexed digital subscriber lines
    Patent number: 7046623
    Abstract: A system (10) and method are provided for restoring the flow of a data stream in the event of a link (28) failure while avoiding delays due to down time. The system (10) for passing the data stream at a particular transmission rate includes a first unit (20, 22) at the first location coupled to one end of each of a plurality of links (28), at least two trained links (28) selected from the links (28) that are set to active status, a second unit (22, 20) at the second location coupled to the other end of each of the links (28), and at least one idle link (28), wherein the first unit (20, 22) and the second unit (22, 20) switch to use the idle link (28) to replace any one of the trained links (28) that has failed.

  • Method and system for establishing link bit rate for inverse multiplexed data streams
    Patent number: 6963533
    Abstract: A system and method are provided for determining link characteristics in order to calculate the optimal data rate because of a link failure. The system includes a first unit (20, 22) at a first location coupled to one end of each of a plurality of low capacity data links (28) for assisting in determining the characteristics of each of the links (28), a second unit (22, 20) at the second location coupled to the other end of each of the links (28) for assisting in determining the characteristics of each of the links (28) based on the characteristics of the test signal received at the second unit (22, 20), and a processor coupled to the second unit (22, 20) for determining the optimal transmission rate based on the characteristics of the links (28) and the number of links (28) needed to provide the desired transmission rate.
