PHYSICAL APPEARANCE OF
FRAMES: The physical appearance of
the frame, especially the location of the
MCM, Power Amplifier cage, and Power
Distribution/Combiner cage, and the
particular I/O plate used, may differ on
frames converted from early version
SC4812T BTSs. Functionally however,
and for the purpose of optimization and
acceptance testing, those frames are
identical.
TX Filters
(one per sector)
NOTE:
The fourth PA quadrant (quadrant D– see Figure 1-15) is
populated with CLPAs only whe the 4x4 ETM is
used.
For an SC4812T BTS frame which has been converted
to multicarrier capability, a fourth three–sector
carrier, using BBX–10 through BBX–12, is supported
in R16.4 and later software releases. In a converted
multicarrier frame, PA slot 4 in all PA quadrants
should never be populated.
