1.3.4 Power Feeder
The PIU of the indoor Macro BTS can support a maximum current of 58 A (@-40.5
VDC). In certain installations with a relatively high number of ODUs this current
may not be sufficient to power the shelf and all the ODUs. In such installations
the ODU Power Feeder is used as an additional power source providing power (-48
VDC) to ODUs. It transfers transparently all signals between the AU and the ODU,
while injecting DC power received from an external source. Each ODU Power
Feeder unit can serve up to four ODUs. Up to three ODU Power Feeder units can
be installed in a 1U high Power Feeder panel.
1.3.5 Antenna
In the 4Motion architecture, the antenna is approached as an independent
element. This provides the operator with the flexibility to select the antennas
source according to its supplier policy. To ensure the availability of antennas that
