  • Patent number: 7975046
    Abstract: Methods, systems, and computer-readable media provide for verifying a lawful interception system. A first file and a second file are received. The first file is formed by recording data traffic at a computer as the data traffic generated at the computer is transmitted from the computer to a remote network via a broadband remote access server (BRAS), saving the recorded data traffic as a first packet capture and flat file export (PCAP) file, and exporting packet summary lines from the first PCAP file. The second file is formed by intercepting the data traffic as the data traffic egresses from a mediation system to a law enforcement agency (LEA) system, saving the intercepted data traffic as a second PCAP file, and exporting packet summary lines from the second PCAP file. The first file is compared with the second file to verify an accuracy of the mediation system.

  • Patent number: 7570599
    Abstract: Methods, systems, and computer program products adaptively apply a target noise margin to a DSL loop to establish a DSL data rate on the DSL loop. A method involves receiving performance data associated with a quantity of errors detected over a period of time on the DSL loop and adjusting the target noise margin for the DSL loop based on the performance data. The target noise margin is inversely associated with the DSL data rate that can be established and is adjusted in order to maximize the DSL data rate while minimizing the quantity of errors detected over the period of time. Thus, embodiments of the present invention allow a maximum data rate that can be sustained on a DSL loop without an excessive quantity of errors.

  • Patent number: 7558213
    Abstract: Methods and apparatus to determine digital subscriber line (DSL) configuration parameters based on current and historical DSL performance characteristics are disclosed. A disclosed method comprises obtaining first data representative of a current maximum attainable DSL speed for a telephone line, collecting second data representative of historical maximum attainable DSL speeds for the telephone line, and determining a maximum capable DSL speed for the telephone line based on the first and the second data.
