cdspDtmfPowerTwist 1.3.6.1.4.1.9.9.86.1.4.1.1.7

This object specifies the relative power level of the high frequency component of DTMF. The low frequency group is always fixed to the value specified by cdspDtmfPowerLevel. When this object is set to 0, the power level of both frequency components is set to the same level. When this object is set to a positive value, the power level of the high frequency component is set to relatively higher specified in this object than the low frequency component. For example if cdspDtmfPowerLevel is set to -120(-12 dBm) and this object is set to 50, the power level of the high frequency component becomes -70(-7 dBm). When this object is set to a negative value, the power level of the high frequency component is set to relatively lower specified in this object than the low frequency component. For example if cdspDtmfPowerLevel is set to -120(-12 dBm) and this object is set to -100, the power level of the high frequency component becomes -220(-22 dBm). The power level of the high frequency component has to be in the data range specified in cdspDtmfPowerLevel. For example if cdspDtmfPowerLevel is set to -200(-20 dBm) and this object is set to -100, the power level of the high frequency component will become -300(-30 dBm) which is out of the range (-250..30) of data specified in cdspDtmfPowerLevel, so -100 is illegitimate for this setting.
