* “Common” are components common to both inputs and outputs. For lDU calculation:
Example 1: Input and output on same EDIO
lDU = Common + Input + Output
lDU = 20.9 + 0.68 + 0.92 = 22.5
Example 2: Input and output on different EDIOs
lDU = lDU EDIO #1 +lDU EDIO #2
= (Common + Input) + (Common + Output)
= (20.9 + 0.68) + (20.9 + 0.92) = 43.4
