| Description | 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. |
