(2) The SDU determines the extent and nature of the analog cockpit and cabin voice
connections from the states of these configuration pins. The functionality of the

MP2A/MP2B, MP2C/MP2D, MP2E/MP2F, MP2G/MP2H, MP4J/MP4K, and
MP5E/MP5F) operate according to the connections selected. ORT item vi for codec
