The FXO Channel Usage Statistics offers FXO Channel Usage Statistic tables depending on the criterion and time period selected.

The Trunk checkboxes are only present when there is more than one FXO ports present on the Quadro. These checkboxes are used to select the FXO port number(s) over which the FXO traffic chart will be built. At least one Trunk checkbox should be selected, otherwise error message appears.

The Time Range of Statistic Table drop down list includes the period (in days) statistics data that is to be collected and the corresponding diagram chart that is to be built.

A group of checkboxes allows to specify information to be displayed (multiple checkboxes may be selected at the time):

• Incoming Calls - number of incoming FXO calls
• Outgoing Calls - number of outgoing FXO calls
• Maximum Active Calls - number of maximum active FXO calls

At least one of these checkboxes should be selected, otherwise error message appears.

The button Show generates a FXO Channel Usage Statistics diagram over the selected criteria. The letters M and K used in the legend of the displayed diagrams show the total number of specified criteria: K means thousands and M millions.
