3.6.1 Control Module
The Control Module manages and controls the repeater and handles alarms. The Control Module keeps track
of all modules in the repeater based on serial numbers. Data is collected from modules within the repeater
such as MCPA, Radio Module and Fibre Optic Converter. The collected data is processed and if an error is
detected the Control Module may send an alarm via a built in modem or via Ethernet to an Operations and
Maintenance Center (OMC).
In addition to collecting data from all modules, the Control Module can also collect status of four external
alarm inputs connected to the External Interface board. The summary alarm status of the repeater can be
indicated on a relay port, available on the external interface connector. This relay can be used to indicate to
external equipment if the repeater is functioning properly.
The Control Module includes a Real Time Clock (RTC). The RTC keeps track of at what time alarms and
events occur. This RTC has its own backup battery in order to keep up proper time keeping even during long
power failures.
The Control Module contains a RS232 port used for local access to the repeater. The USB connector is not
activated in this version of the repeater and cannot be used.
The Control Module can be configured in two different modes:
 Stand-alone Mode – in this mode all communication is made directly with the unit – either locally or
remotely via a modem or Ethernet. The communication with the Axell Element Manager is performed
using a modem or Ethernet.
 Systems Slave – being a systems slave means all communications with the Axell Element Manager is
handled by the Control module in the OMU.
