Figure 76 AMM 6p and AMM 20p in 1+1 XPIC configuration
Each pair of modems placed in adjacent BPI-2 sharing slots (for AMM 20p,
2&3 and 4&5, 6&7 and 8&9, etc.) is related to the same polarization of the
transmitted signal over the same wireless channel. Therefore, the front panel
XPIC cross-cable shall connect modems in alternate slots (2&4 and 3&5, etc.).
See Figure 77 on page 87.
