The actual repeater configuration can be seen at the configuration list which is part of 
the delivery. 
 

 
The task of the duplexer is to isolate uplink from downlink, i.e. to separate the 
transmitting path from the receiving path. The pass bandwidth of the duplexer is the 
entire width of the UL- and DL band of the corresponding network.

With built-in RF probes at the duplexers, test signals can be applied or detected 
(see figure  2-2). The probes are provided with different coupling factors, 30 dB for 
measurements and 20 dB for the optional modem. Each antenna port is equipped 
with one coupler. This facilitates measurements under all operational conditions while 
an antenna or a dummy load may be connected.
