Answer Supervision fields
Current
Reversal
Y/N When this option is selected, the FXO interface sends notice to
make connection upon detecting current reversal from the PBX
(which occurs when the called extension goes offhook).
Answer Delay Y/N When this option is selected, the FXO interface sends the
connection notice to the calling party only when the Answer Delay
Timer expires. The connection notice is sent regardless of whether
or not the called extension has gone offhook.

FXO Supervision Parameter Definitions
Field Name Values Description
Disconnect Supervision fields There are four possible criteria for disconnection under FXO:
current reversal, current loss, tone detection, and silence detection.
Disconnection can be triggered by more than one of the three
criteria.
Current
Reversal
Y/N Disconnection to be triggered by reversal of current from the PBX.
Current Loss Y/N Disconnection to be triggered by loss of current. That is, when
Current Loss is enabled (“Y”), the TalkAnytime will hang up the
call at a specified interval after it detects a loss of current initiated
by the attached device.
Current Loss
Timer
200 to 2000
(in milliseconds)
Determines the interval after detection of current loss at which the call
will be disconnected.
Silence
Detection
Enable
Y/N Enables/disables silence-detection method of supervising call
disconnection.
Silence
Detection Type
One-Way or
Two-Way
Disconnection to be triggered by silence in one direction only or in
both directions simultaneously.
Silence Timer
in seconds
integer value Duration of silence required to trigger disconnection.
