Access Unit Indoor Module (AU-IDU)

The double Euro Access Unit IDU module contains the wireless IEEE 802.16a
MAC and modem and is responsible for the wireless network connection
establishment and for bandwidth management. Each AU IDU includes two
3.5/1.75 MHz PHY channels that can connect to AU-ODUs. If only a single AU
ODU per AU-IDU is used, it should be connected to the ODU1 (Channel 1)
connector.
