It is a high end sound chip (CODEC) and the modem is done in software. It is packaged with GPIO pins brought out to monitor and control the DR-1X. Drivers for the sound CODEC and GPIO management are implemented to drive the UDRC and DR-1X repeater.
One could implement similar functionality in piecemeal fashion, however, NW Digital Radio has packaged it for you and makes for a simple installation.
