Figure 2-5 shows the Event-HD digital radio and interfaces from a functional point of 

view. The functional partitions for the I/O, Modem/IF, power supply modules, up/down 
converters, and internal RF duplexing partition are shown. The SDIDU

TM

 comes with the 

standard I/O capability which can be upgraded. The Modem/IF function is modular 

allowing the addition of a second Modem to support protection or ring architectures. The 
power supply is similarly modular. In addition, the ODUs are interchangeable allowing 

use of a single IDU in licensed, unlicensed, and short-haul applications by swapping the 
RF component.
