<h2>Purpose</h2>

<p>This procedure describes how to expand an existing Nokia
Talk-family BTS with an UltraSite or a MetroSite BTS. You can use the BSC
MML or Nokia NetAct. For instructions on how to maintain sites that support
Multi BCF using the NetAct, see <em>Maintaining Multi-BCF Sites</em>
in the NetAct documentation set.</p>

<div class="preconditions">
<a name="p2xhtm-repid-3" shape="rect"></a>
<div class="topic">
<h2>Before you start</h2>

<p>Make sure of the following:</p>


<ul>
<li><p>TRXs of the Talk-family BTS are in the WO state</p>
</li>
<li><p>UltraSite or MetroSite BTS has been installed but not yet created</p>
</li>
<li><p>synchronisation between the BTS sites has been installed</p>
</li>
<li><p>Abis lines are connected</p>
</li>
<li><p>ET has been connected to the Abis interface and LAPD links have
been created for the UltraSite BTS or MetroSite BTS.</p>
</li>
<li><p>If Recovery for BSS and Site Synchronisation is used in the BTS
site, the Talk-family BCF SW should be DF7, and it should be defined and activated
to use Site or BSS synchronisation.</p>
</li>
</ul>


<p>During the BSC software installation the system has created a segment
for each existing BTS. The number of the segment is the same as the number
of the related BTS, for example BTS-32 =&gt; SEG-32.</p>
