Figure 1-4: BTS Expansion Frame (–48 V configuration)
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
BTSs. Functionally however, and for the purpose of
Optimization and ATP, those frames are identical.
