<h1>Serial and Version Number Storage</h1>

<p>The unit version and serial numbers can be locally stored
into the non-volatile memory of BTS. Information must be manually entered
to the BTS with the help of the BTS MMI. A light pen can be used to read the
bar codes attached to the BTS units. Information stored can be later retrieved
and changed with the BTS MMI if, for example, configuration is expanded or
units are replaced. This way it is possible to have an up-to-date bookkeeping
of site unit identifications.</p>


<p>In Nokia 2nd generation BTSs the serial and version number
information is a part of the HW database file. In Nokia Talk-family and PrimeSite
BTSs, information is stored into a separate file that can be handled independently
from the HW database. This enables database file sharing between different
sites having exactly the same HW configuration.</p>


<p>The stored data includes unit name, generation and version
of the unit, hardware and firmware versions, serial number, and the location
information. The actual user interface of this feature is at the NetAct. There
are several alternatives on how to filter or selectively retrieve information
concerning certain sites, units, versions etc.</p>
