Output
Port
Select the functions of the GPO port either as a specific info about ring or
call connection or to output the state of the DTMF detection circuit.
Remote Off
- remote GPO has no function.
Remote Ring
- remote GPO reflects Ring detection.
Remote Connected
- remote GPO is active when the unit is connected.
Remote DTMF Detect String
- remote GPO is active once the DTMF String
below has been detected from the caller.
Remote DTMF Toggle String -
remote GPO is toggled every time the DTMF
String below has been detected from the caller.
Remote DTMF Follow Hash
- remote GPO is active while the DTMF Hash
character is detected from the caller.
Remote DTMF Hash Toggle
- remote GPO is toggled every time the DTMF
Hash character is detected from the caller.
Some networks
– especially PABXs - can have short, low level DTMF
signalling. The DTMF parameters for Threshold and duration can be set
here to account for this. The Threshold defaults to 108 which is approx.
equivalent to -12dB and can be decreased/increased for lower/higher level
signals. The Duration is the number of tests to be performed, with each
test taking slightly over 25ms, so the default of 2 represents a duration
of around 51msec. A longer duration will allow for a more consistent
result, but requires that the DTMF signal is present for longer. Conversely,
a shorter number of tests could have the propensity to generate false
positives when audio is present
If you select DTMF Detect/Toggle then set a the DTMF Detect String to a
character or string for detection.
Finally the serial port can be made to reflect any DTMF signals directly as
they are selected via a DTD:x (DTMF Tone Detect) where x is the DTMF
signal detected.
