36 • FXO interface configuration
Configuring how to detect a call has disconnected (optional)
When a call has disconnected, the FXO interface may detect and verify the termination of the phone call by
three different methods.
three different methods.
•
Detect a busy tone or release tone
•
Detect a loop break (if provided by the FXS switch)
•
Detect battery reversal (if provided by the FXS switch)
•
Detect a dtmf signal
•
Configure loop break timing
The selection of the method, if any of the three, is via the
disconnect-signal
command. The default enables
only loop-break. Upon detecting a loop break, the FXO interface proceeds to clear the call on the SmartNode.
In some instances, the user may need to transmit all of the in-band information (tone signal, announcement)
to the end party after disconnection has occurred.
In some instances, the user may need to transmit all of the in-band information (tone signal, announcement)
to the end party after disconnection has occurred.
The
disconnect-signal
command can be used to enable or disable the three detection methods. If all three
methods are disabled, the call is cleared after a period of 30 seconds from reception of the disconnect signal.
Consequently it becomes the responsibility of the end party to execute the on-hook (completing the discon-
nection phase) for the call to be completely cleared.

Verify that the busy and release tones are correctly configured for the country

The default is Loop-break. To disable it, use
the no inverse command. Should all three
methods be disabled, the call is cleared 30
seconds after receiving the disconnect signal.
The default setting of loop-break is not dis-
played in the running-config output.

[name] (if-fxo) [interface]#loop-break-duration
[min <min-time>] [max <max-time>]
[min <min-time>] [max <max-time>]
Specifies the timing of the loop break signal.
Shorter breaks are ignored, longer breaks
are treated as line down.
Min specifies the minimum time of a valid
loop break (Default 60ms). Max specifies the
maximum time of a valid loop break (Default
600ms). Please note that the internal timer
has a resolution of 40ms.
