Matrix SETU VFXTH System Manual
When an outgoing call is made from the FXO Port and Answer Supervision is set to Battery Reversal, the
system will disconnect the call if it does not mature within 120 seconds.
•
Disconnect Supervision
is the signal given by the CO to detect far end disconnection (when the called
party has gone On-hook).
Select the appropriate
Disconnect Supervision
type from the options according to the type supported by
your CO network:
•
None:
Select this when no signaling is available from the CO.
•
Battery Reversal:
Select this when call disconnection is signaled in the form of Battery Reversal.
When the call is disconnected by the remote user, the polarity of line gets reversed, the FXO Port is
released (free) and caller gets error tone.
•
Open Loop Disconnect:
Select this option when call disconnection is signaled in the form of Open
Loop Disconnect signal. The system will check Open Loop Disconnect signal for the time configured as
the Open Loop Disconnect Timer.
If Open Loop signal is detected for the time less than the Open Loop Disconnect Timer configured, it
will not be considered as a valid Open Loop signal for releasing the port. If Open Loop is detected
continuously at least for the time set in the Open Loop Disconnect Timer, it is considered as a valid
Disconnect signal. After this signal is detected, the call will be released and caller will get error tone.
If you select this option, you must configure the Open Loop Disconnect Timer.
•
Open Loop Disconnect Timer:
If you selected Open Loop Disconnect, you may set the value of
this timer, as required. Default: 200 milliseconds. Valid range: 001 to 999 milliseconds.
Default: Open Loop Disconnect.
•
Disconnect Tone Detection is used by the system to release the FXO Port, when the remote party goes
On-hook or disconnects the call. The tone detection is applicable for both incoming and outgoing calls
made on/ from the FXO Port.
Select the
Disconnect Tone Detection
check box, if you want the system to
detect Call Disconnect Tone
sent by CO network on the FXO Port.
•
If you enable Disconnect Tone Detection, you must select the
Disconnect Tone Type
you want the
system to considered as Call Disconnect Tone on the FXO Port. You can select from:
•
Disconnect Tone 1
•
Disconnect Tone 2
•
Disconnect Tone 3
•
Disconnect Tone 4
•
Ring Back Tone
•
Error Tone 1
•
Error Tone 2
•
Busy Tone
•
Confirmation Tone
•
Feature Tone
•
Routing Tone
•
Intrusion Tone
