2.1.4.1 AC/DC Power Distribution – Base Radio

Figure 2-10 AC and DC Power Distribution in the GTR 8000 Base Radio

If present, the base radio operates from AC power as the preferred power source. When AC power is not available,
the base radio switches to operate from the DC source. Operation returns to the AC source when the AC source is
restored. Switchover from AC to DC and back again is fully automatic. No operator action is required.
The Main DC output of the power supply is used to provide power to the power amplifier and the transceiver. The
Auxiliary output of the power supply is not used within the base radio, but is reserved for use as a redundant power
input to other site components such as the site controller.

2.1.4.2 Power Supply Battery Charger

The power supply includes an integrated battery charger. The battery charger is controlled entirely through software
residing on the associated device module. Software contains the information on supported battery types and obtains
user-specific information pertaining to the particular site. The device software receives battery bus voltage and
battery temperature information from the power supply and uses these variables in conjunction with supported
battery charging profiles to return a signal which sets the charger output voltage appropriately. The battery charge
and temperature conditions may be viewed through Configuration/Service Software (CSS) and Unified Network
Configurator (UNC) or through alarms to Unified Event Manager (UEM).
