Chapter 3 – Related MultiVOIP Setup Parameters
FXO Parameters. The parameters applicable to the FXO telephony interface type are shown in the figure below and described in the table that follows.
| FXO Interface: Parameter Definitions | |
Field Name | Values | Description |
Interface, FXO | Y/N | Enables FXO functionality |
Dialing Options |
| |
Regeneration | Pulse, DTMF | Determines whether digits generated and sent out will be pulse tones |
|
| or DTMF. |
Message | Not applicable to FXO interface. | |
Waiting |
|
|
Indication |
|
|
Inter Digit | 50 to 20,000 | The length of time between the outputting of DTMF digits. |
Regeneration | milliseconds | Default = 100 ms. |
Time |
|
|
FXO Disconnect On | There are three possible criteria for disconnection under FXO: current | |
|
| loss, tone detection, and silence detection. Disconnection can be |
|
| triggered by more than one of the three criteria. |
Current Loss | Y/N | Disconnection to be triggered by loss of current. That is, when |
|
| Current Loss is enabled (“Y”), the MultiVOIP will hang up the call |
|
| when it detects a loss of current initiated by the attached device. |
Current Loss | integer values | The minimum time required for detecting the current loss signal on |
Detect Timer | (in milliseconds ) | the FXO interface. In other words, this is the minimum length of |
|
| time the current must be absent to validate ‘current loss’ as a |
|
| disconnection criterion. Default = 500 ms. |
Tone Detection | Y/N | Disconnection to be triggered by a tone sequence. |
