3.6 Hardware Identification
An OMU contains a number of different modules. Some of these are active devices containing a micro
controller, and some are passive devices.
The Control Module communicates with the active devices using a master/slave configuration, where the
Control Module is the master and the active devices are slaves. Each active device uses its serial number as an
address. A slave only replies to requests with the correct address information.
During manufacturing the OMU is configured with all the serial numbers of all the devices in the system. For
passive devices, the article number of the device is added. Once the system is configured, the Control Module
polls all the active devices for article numbers and production information as well as software versions and
statistics of the active devices.
Via the RMC the full repeater inventory can be read, including statistics of the active devices.
When a login to an OMU is made using the Repeater Maintenance Console, the RMC detects that it is an OMU
and adjusts the user interface correspondingly. The same RMC can be used also for all repeater types.
Via the RMC basic information about the OMU configuration can be monitored.

3.7 ID and TAG
When the OMU is integrated into the Axell Element Manager the OMU is assigned an ID, which is a unique
identifier in the repeater network. This ID is used by the AEM to keep track of the OMUs and repeaters in the
AEM database.
