7 INTERFACE PANELS (ACCESSORY)
The interface panels are accessory items that are used when multiple BTS’s and multiple HU’s
require connection or when RF attenuation is needed between the BTS and HU. Two types of
panels are available: the Conditioning Panel and the Duplexing Panel. The Conditioning Panel,
shown in Figure 2-11, provides attenuation of the forward path signal to the level required for
input to the HU. The Conditioning Panel also provides forward and reverse path combining and
splitting (as needed) to enable multi-BTS to single HU, multi-BTS to multi-HU, or single BTS
to multi-HU configurations.
Figure 2-11. Conditioning Panel
The Duplexing Panel, shown in Figure 2-12, is used in conjunction with the Conditioning Panel
when the BTS provides a duplexed forward and reverse path RF connection. The Duplexing
Panel separates the duplexed forward and reverse path signals. This allows the BTS to be
connected to the HU which has separate forward and reverse path RF ports. For complete
information about the Conditioning Panel and Duplexing Panel, refer to the Digivance RF
Transport Solution 800 and 1900 MHz Interface Panels User Manual (ADCP-75-144).
