3.11 Integrate into the AEM
When the OMU has been installed at site and the remote communication has been enabled, the OMU
can be integrated to the Axell Element Manager. This is done by the operator of the AEM. After
entering the telephone number to the OMU, the AEM dials up the OMU, downloads all the OMU
parameters and statuses into a database. When all parameters have been downloaded, the AEM
configures the OMU with the telephone number where alarms and reports should be sent, and
optionally with a secondary telephone number where the repeater can dial in case connection to the
primary number fails.
When heartbeat reports and alarms are sent from the OMU to the AEM also the latest information
about the status and RF-configuration is included. This means that the AEM operator always has
information about the current status in the AEM database (and do not need to call the repeater to
find this out).
Note! Once the OMU is integrated to the AEM, all changes to the OMU should preferably be done
from the Axell Element Manager in order to ensure that the database always contains correct
information.
