<h1>Nokia Autoconfiguration in the Nokia GSM Office Solution</h1>

<p>The Autoconfiguration feature guides the user step-by-step
through the whole commissioning process. The autodetection feature finds and
reports active units to the Nokia NMS, reducing the number of system data
entries required. These new features reduce the time spent at the site significantly.</p>


<p>The purpose of the Autoconfiguration feature is to establish
a transmission link between the BSC and BTS and issue the new BTS to the NMS,
which then continues automatically by testing the BTS. If this test is successful,
the BTS becomes integrated into the network.</p>


<p>When the RNW object and O&amp;M and transceiver signalling
links have been created in the BSC and after the transmission objects related
to the Nokia InSite GSM Base Station have also been saved in the BSC, the
AC pools are created in the ET PCM. The size of the pool can vary from 2 to
31 TSLs (ETSI) or from one to 24 TSLs (ANSI). One or several pools can be
created in the same PCM, but one pool cannot be divided into two PCMs.</p>


<p>The pool is created as a continuous block of 64k timeslots.
The BSC reserves the circuits so that they cannot be used for other purposes
without deleting the pool first. The BSC automatically creates and activates
the access channel into the last timeslot of the AC pool, which is used for
communications between non-commissioned base stations and the BSC. After that,
the BSC is ready to serve the accessing BTS.</p>


<p>The BTS to be commissioned has started the Autoconfiguration
and, after it has found the access channel, it requests the BSC to allocate
the Abis circuits for the signalling and traffic channels. The BSC allocates
the required circuits and sends the allocation layout to the BTS.</p>


<p>The BTS start up continues with O&amp;M signalling link
activation. The BSC updates the allocated Abis circuits to the RNW database
and LapD channel definition files in the memory and on the hard discs. The
BSC also informs the NMS/2000 about the allocated circuits.</p>


<p>The success of the autoconfiguration process is tested
automatically. The Abis loop test is performed automatically in order to verify
Abis transmission connections end-to-end. If the tests are passed, an indication
is given to the installer at the BTS site, and the BSC informs the NMS/2000.</p>


<p>After the Autoconfiguration process is over, each FXC E1/T1
or FXC RRI that has a new permanent cross-connection raises a “configuration
changed” alarm. The NMS/2000 uploads the new transmission settings of the
affected transmission units. The BTS software stores a backup of the Transmission
Unit's branching table and LapD link positions to the BOI’s flash memory.</p>


<p>The Autoconfiguration log of events is stored in the Commissioning
Report when the configuration is performed from the configuration wizard.</p>


<p>Nokia Autoconfiguration and autodetection features make
commissioning and integrating the Nokia InSite GSM Base Station fast and easy.</p>
