12.1 Software updates
New SW versions can be downloaded while BTS is working. The software can be loaded
either locally, with the BTS Site Manager software, or remotely from NetAct
TM
. Site visits
are unnecessary for routine operation and maintenance (O&M) tasks.
Typically, local software download is done only when the NetAct
TM
connection is
missing, for example, during the commissioning process. Software can be downloaded
as a background operation without interrupting the BTS operation. The new software
can be activated at any time. Reboot is required in order to put the software into use.
Flexi Lite BTS only uses downloadable software. All software can be downloaded and
updated from NetAct
TM
. This procedure is centralized, meaning that several BTSs can
be upgraded with the new software either simultaneously or one by one.
Flexi Lite BTS keeps the current and previous software packages in its flash memory.
Either of these software versions can be activated at any time. Reboot is required in
order to put the software into use. Updated software (current and previous) in the BTS
can be seen through BTS Site Manager/NetAct
TM
.
RAN2423: SW Verification Agent ensures that only integrity-verified software can be
installed and run in Flexi Lite BTS and no malicious code can be inserted.
12.2 External alarms and controls
BTS inputs and outputs can be configured and tested locally at the BTS site with BTS
Site Manager. External alarm inputs are used for collecting customized alarms in the
BTS. Flexi Lite BTS provides six external alarm inputs and two external control outputs.
The interface used is HDMI.
In normal operation, the external alarms and control outputs of the BTS are managed
from NetAct
TM
after they have been configured.
12.3 Counters
Counters are used to monitor performance of a BTS in the network. They can measure,
for example, the number of MAC-hs PDUs correctly delivered with more than 5 retrans-
missions, number of rejected radio link setup requests because of congestion.
For the full list of counters and their descriptions, see Flexi Lite BTS Counters .
Counters can be monitored through NetAct
TM
.
