<h2>Introduction</h2>

<p>This breaks down each business day into half-hour periods, showing the
maximum and average number of telephone lines in use in any
particular half-hour.  You can opt to exclude weekends, when perhaps
not many calls are being made or received, and so as not to distort
the averages.  You can also concentrate on incoming or outgoing
calls.</p>

<h2>Running the report</h2>

<p>On the Reports screen, either double-click on the <span class="reference">Trunks Busy</span> report in the reports list or select the <span class="reference">Trunks Busy</span> report and press the <img class="icon" src="http://www.tri-line.com/common/img/documentation/tim_professional/run_now_button.png" /> button, as shown below:</p>

<p>The following screen will be displayed:</p>

<h4>Select a report period</h4>

<p>You need to select a time period for which you want the report to produce
information for.  You can select a pre-set period from the drop-down
list.</p>

<p>The default is set to <span class="keyword">Last Month</span> (the period from the first day to the last day of the previous calendar month, and NOT the last 30 days).</p>

<h4>Or enter your own custom period</h4>

<p>If you want to specify a period not
shown in the list, just enter your start and end
dates and times manually into the boxes provided.</p>

<h4>Choose a site to report on (optional)</h4>

<p>If your system is set-up to administer multiple sites, you have the
option of selecting a particular site here.  Select the blank line
(or leave the box empty) to report on all of your sites.</p>

<h4>Choose a specific trunk group (optional)</h4>

<p>You have the option of limiting the report's results to a particular
trunk period, for when you want to see how well a particular group of
trunks is performing, but don't want the results from other trunks to
distort your results.  Leave blank for all trunks to be included in
the results.</p>

<h4>Select a particular trunk (optional)</h4>

<p>To view only the results for a particular trunk, enter the number in box provided.</p>

NOTE: If the trunk group and trunk number is left blank the report will use the data from all of your trunks.

<h4>Filter by partial dialled number (optional)</h4>

<p>You can choose to run the report using data from calls made to a
particular dialled number.  This can help when deciding if a private
wire is feasible. For example, let's suppose you have two offices:
one in London and the second in Reading.  You would enter the number
of the Reading office in to the Dialled Number box.  The resulting
report will show you how many trunks where busy at any one time to
your Reading office.  You would then know how many private wires you
need to install.  You could use this information in conjunction with
a Custom Report, and specify the same number of your Reading office,
to show you how much it is currently costing you to call the Reading
office.  Taking into account other charges such as line rental, you
could then make an informed decision as to whether or not it would
save you money by installing the private wires.</p>

<p>The number you enter can include wildcards, (eg. 0118* or 0161 500 5*)</p>

<h4>Filter by partial location name</h4>

<p>You can run this report for the same reasons above but for more than one
number, or to determine whether it would be cost effective to set up
a peering arrangement with a carrier in the region you call most
often.  Location names can include wildcards (eg. Manche*)</p>

<p>Used in conjunction with the Call Locations feature (see later), this option becomes a very powerful decision making aid.</p>

<h4>Weekend calls</h4>

<p>You can opt to exclude calls that are made over the weekend period by
selecting this option; calls made at these times may distort your
results.</p>

<h4>Type(s) of calls</h4>

<p>The default is to report on all calls. If you want to report on incoming
calls only or outgoing calls only, deselect the type of call you
would like to exclude.</p>

<h2>Creating the Report</h2>

<p>When you have chosen a reporting period, and are happy with your selections, click on the <span class="button">Run Now</span> button.</p>

<h2>The results</h2>

<img class="screenshot naked" src="http://www.tri-line.com/common/img/documentation/tim_professional/trunks_busy_3.png" alt="Trunks busy" />

<p>As with all reports, the header of the report includes the report title,
any name you may have given to it, the period from which call data
was used, and any other options you selected such as specific dialled
numbers and trunks.</p>

<p>The report consists of two parts: a graph and a table.</p>

<p>The graph is a quick and easy indication of your line usage, broken down
into a day's half-hour timeslots. The percentage on the y-axis shows
the percentage utilisation.  The x-axis shows the start point of each
hour of the day.</p>

<p>The bars on the graph are coloured to show the maximum number of trunks
busy in each particular half-hour (in light blue), overlaid by a bar
showing the average number of trunks busy in the same period (dark
blue).  There are two bars in each hour period, each one being a half
hour.</p>

<p>The table shows the actual data for each half hour of the day.  It also splits the
data into incoming calls and outgoing calls, as well as providing a
total for all types of calls. The table holds the following
information for each half-hour period:</p>

<table class="confluenceTable">
	<tbody>
		<tr>
			<th class="confluenceTh">Column header</th>
			<th class="confluenceTh">Description</th>
		</tr>
		<tr>
			<td class="confluenceTd"><b>Time Slot</b></td>
			<td class="confluenceTd">The time of day in half-hour periods.</td>
		</tr>
		<tr>
			<td class="confluenceTd"><b>Max Busy</b></td>
			<td class="confluenceTd">Shows the maximum number of trunks in use during the time slot shown.</td>
		</tr>
		<tr>
			<td class="confluenceTd"><b>Average Busy</b></td>
			<td class="confluenceTd">Shows the average number of trunks in use during the time slot shown.</td>
		</tr>
		<tr>
			<td class="confluenceTd"><b>Total Duration</b></td>
			<td class="confluenceTd">The total time when trunks were busy, both incoming and outgoing combined.</td>
		</tr>
	</tbody>
</table>

<h2>Summary</h2>

<p>The summary at the end of the report is fairly self-explanatory as you can see from the sample summary shown below:</p>

<p>The maximum number of calls at any time during this period was <span class="keyword">10</span>.<p>

<p>The 'maximum average' was <span class="keyword">6</span> calls.</p>

<p>The first time you reached your maximum was on <span class="keyword">Thursday 23 Aug 2012</span> at <span class="keyword">10:34:33</span>.</p>

<p>In total, <span class="keyword">548:16:39</span> of time was spent on calls.</p>
