9.7.1 BTS Attenuation Setting
The UDC input power is limited. An internal attenuator allows inputs of +10 dBm to +33 dBm. In case
the output is larger a separate attenuator on the downlink only is required.
Switches represent values of: 1, 2, 4, 8, 16 dB.
The left most switch has the highest attenuation – 16 dB. The right most switch represents the least
attenuation – 1 dB.
The output level of the downlink cellular signal in the Alvarion band should be 0±1 dBm.
The following figure demonstrates the location of the attenuator:

9.7.2 Gain Configuration
The UDC has internal attenuators that allow you to control the Pilot signal level and up link and down
link gains
Switches represent values of: 1, 2, 4, 8, 16 dB.
The left most switch has the highest attenuation – 16 dB. The right most switch represents the least
attenuation – 1 dB.
All signals are pre-configured according to network parameters.
