1.3 Functional Description
FA4800 system comprises of the following units:
• Outdoor Unit (ODU): An enclosed aluminum frame with a front sealed
plastic cover, containing an integrated transceiver with an antenna, RF
module, modem and standard interfaces. The ODU stores all the configuration
parameters of the FA4800 system. Figure 1-3 shows the ODU block diagram.
• Indoor Unit (IDU-E or IDU-C): The interface unit between the ODU and the
user. It converts 100–240 VAC to -48VDC, and sends it on to the ODU. The
IDU does not store any configuration data. Therefore, there is no need for
additional configuration of the FA4800 system when replacing an IDU.
