The header of the report will display its title, any friendly name you assigned to it, the period of the report and any options you have selected in the report's selection criteria window.

The body of the report consists of a graph and a table:

• The graph is a quick and easy indication of your line usage, broken down into half-hour time slots. The percentage on the y-axis shows the number of lines utilised, and the x-axis shows each half-hour of the day. The bars on the graph coloured light-purple show the maximum number of busy trunks in each particular half-hour, and the overlaid dark-purple ones show the average number of busy trunks in the same time period.
• The table displays the actual data organised in columns for maximum and average busy lines and the total duration for each half-hour time slot. Each column header of the table is described below:
