Antenna Port
In the two band configuration the RU has one duplexed N-female antenna port for
transmitting and receiving signals to and from distributed antennas. In the three band
configuration the RU also has two non-duplexed N-female antenna ports and
for UL and DL. These RF ports can be connected directly to an antenna (i.e. using
RF jumper cables) or through splitters, allowing additional antennas to be fed by the
RU.
Status LED
The status LED provides a visual warning of an alarm condition. The color of the LED
indicates the severity of the alarm.
Expansion Ports
The Expansion UL and Expansion DL ports are QMA female connectors that
are used to connect to a CommScope expansion unit to provide additional bands.
