Access Unit (AU-IDU)
AU-IDU module contains the WiMAX-ready MAC and modem and is responsible for the wireless network connection establishment and for bandwidth management. Each AU-IDU connects to the NPU via the back plane. In addition, each AU-IDU connects to all other AU slots via the back plane over a shared bus. Each AU-IDU includes four channels using a common PHY and MAC that can connect to up to four outdoor radio units, according to the selected diversity mode. The AU-IDU module connects to the AU-ODUs via Intermediate Frequency (IF) cables carrying full duplex data, control and management signals between the AU-IDU and the AU-ODU, as well as power (-48 VDC) and 64 MHz synchronization reference clock from the AU-IDU to the AU-ODU. The IF Tx and Rx frequencies are 240 MHz and 140 MHz, respectively. IDU-ODU service channel at 14 MHz serves for bi-directional control, status and management signaling.
