LED behavior
The unit has two LEDs located on the front panel. One is the power on LED (green) and the other is the
alarm LED (red). Both LEDs can indicate a number of states by different flashing behaviors.
In an error state the web interface should be used to check the actual condition of the BIU but the LEDs
on the front can give you a quick indication on the state of the unit. It is also useful for locating the
physical unit if you have several BIUs installed in the same rack.

DL/UL BTS 1 / 2
This is RF path where the radio base station is connected to the BIU. Do not
exceed the power rating in the downlink for the port.
TP UL 1/2
This is a test port for the uplink. It show the uplink signal in the DL/UL BTS port
- 6 dB. This port is replaced by the UL port on a non-duplexed version of the
BIU.
DL OUT 1/2
These are the output ports for the downlink signals after they have been
treated in the BIU with attenuators and filters.
UL IN 1/2
Here is where the uplinks are connected in to the BIU which will then amplify
and/or attenuate as appropriate.
EXTERNAL ALARMS
Will be used for external alarm monitoring in the future.

The LEDs indicates various states as shown in the table above.
