Note:
l The BTS3606A adopts the CCPM to support CDMA2000 1x, and the CECM to support 1xEV-DO.
l The same BTS3606A cabinet can be configured with CCPM and CECM, that is, the BTS3606A can
simultaneously support CDMA2000 1x and 1xEV-DO.
l The CPCM supports the power combination when the BTS3606 operates at 1900 MHz.
l CTRM and CHPA support the multi-carrier application.
3.3 System Structure
The BTS3606A system consists of baseband subsystem, Radio Frequency (RF)
subsystem, power supply subsystem, and antenna subsystem.
Space is also reserved in the BTS3606A cabinet to hold the transmission equipment
such as the micro wave equipment and SDH equipment to support flexible
transmission access mode.
Figure 3-3 shows the structure of the BTS3606A.
