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.
