Figure 4-5: Enabling the optical ports.

NOTE

Disabling a port will result in the attached AU not transmitting or receiving any signal.

4.2.7 Controlling the Antenna Unit

The changeable parameters in the AU are the downlink and uplink attenuators and

downlink and uplink gain controls.

4.2.7.1 Setting the attenuation values

The values which can be

selected on the GUI represent

attenuation values by which the

gain of the AU can be reduced.

The downlink (DL) and uplink

(UL) attenuators for the AU can

be selected using the drop

down lists. The range of

permitted values is 5 – 31 dB for

all attenuators in steps of 1 dB

(Figure 4-6).

NOTE

The attenuation setting on the AU does not correspond to the actual gain of the unit.
