System status parameters are also combined and their summary indicated by
three LEDs on the repeater cabinet .
The Remote Unit contains the following main units:
• Optical Transceiver
• LPU (Low Power Unit)
•
Distribution front end
• System Power Supply
• Frequency Channelizer that selects the desired operating channel (if
applicable)
Distribution Front End
The distribution front end of the Remote unit consists of:
Duplexer
High Power Amplifier (HPA) for FWD signal
Low Noise Amplifier (LNA) for RVS signal
These are connected to the Distribution Tx/Rx antenna port. Both FWD and
RVS amplification channels are gain-controllable, to obtain the optimal link
balance with minimum noise introduction into the BTS.
