PMU must be installed in the leftmost slot. When assembling an mBDA system with DT Combiner and MT
Combiner modules, CBs and RFUs can be installed in any of the remaining six slots.
With typical configuration of quad band RFU plus two CB, we recommend inserting CBs and RFUs in the
order as shown in Figure 2 to have a better internal cabling. Starting from the left, the mBDA rack should
have PMU, DT Combiner (mBDA-CB-ABPK4ID1), the certified RFUs which can choose 700U MHz, 700L
MHz, 800MHz (ESMR) , 850MHz, 1900MHz, 2600MHz, AWS and EAWS and MT Combiner (mBDA-CB-
ABPK4ID2).
