C.5.3. Concentrated Bus Inputs.
It is expected that the left and right transponders, whether the transponder is a TSS or a TDR, will receive exactly the same infor-
mation. This may be done either through separate or through shared concentrated buses. The only difference is that data will come
in from a different side. Table C-12lists the TDR concentrated bus inputs and the TSS bus inputs and how they correspond.
