<h1>BTS Hardware Database Management</h1>

<p>The BTS hardware database contains an accurate description
of the equipment configuration of the BTS site. The database is stored in
the non-volatile memory of the Base Control Function (BCF) unit of a BTS site.</p>


<p>The BTS Hardware Database Management makes it possible
to manage all the BTS hardware databases without a need to visit the BTS site.
Databases are managed and stored at the BSC, and they are loaded down to the
BCF when necessary. The system enables the operator also to upload the database
from the BCF to the BSC if local modifications at the BTS site have been made.</p>


<p>Database file downloading is executed when the BCF is restarted
if there is no database in the BCF's non-volatile memory. Downloading can
also be done as a background operation when the hardware database is activated.</p>


<p>A new BTS hardware database is transferred into the BSC
on a floppy disk or through the operation and maintenance network by means
of the FTAM (File Transfer, Access and Management) protocol. Database modifications
are made with a PC equipped with a BTS-MMI program. It is possible to edit
a hardware database located in the BSC's disk by connecting the PC to a service
terminal port of the BSC. The modified databases are stored at the BSC for
back up, and they can be loaded down to the BCF.</p>


<p>BTS hardware database management functions can be used
by MML commands at the BSC. The operator can create and delete a hardware
database, attach a database to a BCF, and detach a database. With the activation
command the operator can activate a certain hardware database on a BCF. The
operator can also replace a certain database with another database or erase
the contents of the non-volatile memory of a BCF.</p>


<p>With output commands the operator can list information
of the hardware databases created in the BSC and the hardware database configuration
of BCFs.</p>
