<p>This is the engine room of the TIM system, accessible
by pressing the <img class="icon" src="http://www.tri-line.com/common/img/documentation/tim_professional/tariffs_button.png" /> button on the function button panel
on the main screen.</p>
<p>It gives remarkable flexibility for administering
how your calls are costed. They look quite complicated at first, but
looking a little deeper, things soon make sense.</p>
<p>Collectively, the pricing and dial code information is known as a <span class="reference">Tariff table</span>,
and such a table exists for each network carrier. In some cases, a
single network carrier may have more than one tariff table to cater
for its wide-ranging pricing structures. Each table can be edited
separately, thus allowing complete flexibility in how the system
costs your calls.</p>
<p>The main <span class="reference">Tariffs</span> screen can be seen below:</p>
