  • Techniques for high definition audio modems
    Patent number: 7616627
    Abstract: A system, apparatus, method and article for high definition audio modems are described. The apparatus may include a communications path comprising a communications bus and buffers, a codec to couple to the communications bus, and a processor to couple to the communications bus. The processor may be arranged to execute instructions for a software modem to determine a round trip delay value for a communications path, and adjust the round trip delay value by varying input to one of the buffers. Other embodiments are described and claimed.

  • Pad and CODEC detection
    Patent number: 7424051
    Abstract: A Digital Impairment detection scheme which is designed for providing reliable estimate of digital impairments such as PAD, and CODEC type in the presence of digital impairments such as Robbed Bit Signalling and non G.711 complaint network CODECs and analog impairments such as IMD, noise and changing line conditions. This estimate is used to derive optimum transmit symbol constellations for a modem connected digitally to a trunk so as to maximize its data transmission rate.
