• The AIU board has RF jumpers/cables to be able to allow for different RBS
configurations with the same board. The jumpers connects combiners and
splitters that are applicable for a certain configuration.
• The PCU contains a number of switches for the power system.
• The GPB and all device boards are equipped with a reset button. (The
button is not reachable from the front of the board).
Incoming External Power
The RBS can be fed by either AC, DC +24V or DC -48V depending on the
power equipment.
External Alarms and Output
The RBS supports external alarm input ports for both Ericsson or
customer-specific use. The operator can configure whether an if an alarm
generated by closed or open loop condition. Closed loop means that an alarm
is triggered when an open switch is closed, and open loop condition means
that an alarm is triggered when a closed switch is open. A number of external
output ports for control of external equipment are also available in the RBS.
The ports are controlled from a management interface.
Connectors, cables and screws
This is the actual mechanical interface for the RBS. The interface specifies the
mounting of boards into subracks, and how to mount subracks in cabinets.
