<h2>Nokia MetroSite Base Station</h2>

<p>In the Nokia MetroSite Base Station, there is no HW database
file to be up/downloaded. The MetroSite BTS gathers all information required
from the following sources: the BTS SW package, BTS configuration file, transmission
configuration file, autodetection procedure at the BTS, BSC configuration
data, and calibration data.</p>


<p>A possible change in any of the information elements causes
an automatic database update onto non-volatile memory. The configuration is
detected in normal start-up situations and in configuration changes. The latter
includes cases in which extra capacity (that is, more TRXs) is added or a
faulty unit is replaced with a new one.</p>


<p>The plug-and-play functionality is enabled since the Nokia
MetroSite system data can be back-up copied to a slave TRX and the transmission
configuration can be back-up copied to the master transceiver.</p>
