threshold (FXO only) is configured by the
CurrentDisconnectDefaultThreshold parameter. The frequency at
which the analog line voltage is sampled is configured by the
TimeToSampleAnalogLineVoltage parameter.
Note: This parameter can also be configured in a Tel Profile.
Defines the voltage change slope during polarity reversal or wink.

[0] = (Default) Soft reverse polarity.

[1] = Hard reverse polarity.
Notes:

This parameter is applicable only to FXS interfaces.

Some Caller ID signals use reversal polarity and/or Wink
signals. In these cases, it is recommended to set the
parameter PolarityReversalType to 1 (Hard).

For this parameter to take effect, a device reset is required.
Defines the duration (in msec) of the current disconnect pulse.
The range is 200 to 1500. The default is 900.
Notes:

This parameter is applicable for FXS and FXO interfaces.

The FXO interface detection window is 100 msec below the
parameter's value and 350 msec above the parameter's value.
For example, if this parameter is set to 400 msec, then the
detection window is 300 to 750 msec.

For this parameter to take effect, a device reset is required.
Defines the line voltage threshold at which a current disconnect
detection is considered.
The valid range is 0 to 20 Volts. The default is 4 Volts.
Notes:

This parameter is applicable only to FXO interfaces.

For this parameter to take effect, a device reset is required.
Defines the frequency at which the analog line voltage is sampled
(after offhook), for detection of the current disconnect threshold.
The valid range is 100 to 2500 msec. The default is 1000 msec.
Notes:

This parameter is applicable only to FXO interfaces.

For this parameter to take effect, a device reset is required.
