<h2>Before you start</h2>

<p>In an operating network, you can test the feature by using
the MML command <span class="command-sem">ERO</span> to verify the TRXs
from which the TCHs are allocated.</p>


<p>A BTS that has no super-reuse TRXs configured is chosen
to be the target for testing.</p>


<p>Uplink interference of channels is a major factor in deciding
the TRX from which the traffic channel is allocated. Because of this, the
uplink inteference levels between TRXs in the target BTS should not vary too
much.</p>

in NetAct documentation set gives instructions on how to plan and prepare
parameter changes, for example when bringing new features into use in the
GSM and WCDMA networks.</p>
