<h3>LMU parameters</h3>

<p>The following timer parameters can be seen with LMU Manager. The default
values are valid and they should not be changed.</p>


<ul>
<li><p><span class="parameter-sem">Time from fix lost to clock out alarm</span></p>


<p>This parameter defines the time between GPS fix lost alarm (<span class="alarm-sem">8048</span>)
and clock alarm (<span class="alarm-sem">7601/7602</span> for UltraSite/MetroSite
or <span class="alarm-sem">7876</span> for Talk-family BTSs). After this time, the
BSC starts the synchronisation recovery actions.</p>


<p>The default value is 240 s.</p>
</li>
<li><p><span class="parameter-sem">Time from clocks out to clock disable</span></p>


<p>This parameter defines for how long the LMU keeps sending the frame
clock signal after clock alarm <span class="alarm-sem">7602</span> or <span class="alarm-sem">7876</span>.
This time is required for forced handovers before the automatic recovery actions
take place.</p>


<p>The default value is 60 s.</p>
</li>
<li><p><span class="parameter-sem">Automatic clock output</span></p>


<p>Because BSC controls the LMU clock output, the default value (Off) must
be retained for this parameter when BSS Synchronisation is used.</p>
</li>
</ul>
