Configuration Examples of S-Type Site 
The S-type site may serve either two-sector cells or three-sector cells. And 
the directional antenna is often employed.  
The configuration of the S2/2/2-type site will be described below. 
The configuration of the S2/2/2-type site is shown in Figure 92. 
Generally, the S2/2/2-type site is configured with 2 CDUs (special 
treatment for CDU, see Appendix C) for each sector and 2 omni-antennas.  
For the logical connection relationship between the combiner units and 
distribution units of each sectorized cell, refer to the connections of O2.
