• IXJCTL_DAA_COEFF_SET

    ioctl(ixj1, IXJCTL_DAA_COEFF_SET, iCoeff)

    Return Value

    Returns TRUE if the coefficient code was accepted.

    Parameters

    The coefficient code to use.

    Remarks

    Selects the country-of-origin setting of the PSTN Central Office. This programs the DAA to match the electrical specifications for the telephone equipment on the other end of the PSTN port. This includes audio impedance, current, and voltages used for signaling functions and voice transmission. This does not automatically program filter detectors to detect call progress tones. If this call fails the DAA is in an undefined state and may not function at all. Generally a failure indicates the hardware must be reset.

    CO equipment currently supported:

    DAA_US, DAA_UK, DAA_FRANCE, DAA_GERMANY, DAA_AUSTRALIA, DAA_JAPAN
