<h2>TRX tests</h2>

<p>When a TRX test command is activated from the BSC to the
IDD TRX, the loop is executed via the IDD main TRX only.</p>


<p>When the test is activated via the BTS Manager, it is possible to execute
the TRX test to either the IDD main or auxiliary TRX, according to test activation
command from the BTS Manager. In the test activation command, either <span class="gui-component-sem">Loop Test through Main</span> or <span class="gui-component-sem">Loop
Test through Auxiliary</span> is selected.</p>
