• IXJCTL_DAA_AGAIN

    ioctl(ixj1, IXJCTL_DAA_AGAIN, iGain)

    Return Value

    None.

    Parameters

    The gain code to use.

    Remarks

    Selects the analog gain for both input and output at the DAA amplifiers on the PSTN port. The input parameter is OR'ed with the output parameter and passed in to the ioctl. The receive gain (AGRR) ranges from 0 to 6db. The transmit gain (AGX) ranges from–6db to 3.5db. The default values are 0dB for both transmit and receive.

    The parameters are:

    AGRR00DBAnalog gain in receive direction 0dB
    AGRR3_5DBAnalog gain in receive direction 3.5dB
    AGRR06DBAnalog gain in receive direction 6dB
    AGX_6DBAnalog gain in transmit direction -6dB
    AGX_2_5DBAnalog gain in transmit direction -2.5dB
    AGX00DBAnalog gain in transmit direction 0dB
    AGX3_5DBAnalog gain in transmit direction 3.5dB
