52.11.9 Tone Parameters

This subsection describes the device's tone parameters.
52.11.9.1

Telephony Tone Parameters

The telephony tone parameters are described in the table below.
Parameter
[EnableMOH]
Version 6.6

[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.
Tone Parameters
Enables the option for using an external audio source that is
connected to the device's AUDIO connector (on the CPU
module). When enabled, the device uses the incoming audio from
this connector instead of playing the held tone defined in the Call
Progress Tones (CPT) file.

[0] = (Default) Disable

[1] = Enable
