Parameter Description
it back on call release.
The FXO interface sends a 200 OK response when polarity
reversal signal is detected (applicable only to one-stage
dialing) and releases a call when a second polarity reversal
signal is detected.
Note: This parameter can also be configured in a Tel
Profile.
Web/EMS: Enable Current Disconnect
[EnableCurrentDisconnect]
Enables call release upon detection of a Current
Disconnect signal.

[0] Disable = (Default) Disable the current disconnect
service.

[1] Enable = Enable the current disconnect service.
If the current disconnect service is enabled:

The FXO releases a call when a current disconnect
signal is detected on its port.

The FXS interface generates a 'Current Disconnect
Pulse' after a call is released from IP.
The current disconnect duration is configured by the
CurrentDisconnectDuration parameter. The current
disconnect 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.
EMS: Polarity Reversal Type
[PolarityReversalType]
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.
EMS: Current Disconnect Duration
[CurrentDisconnectDuration]
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.
