The NSSP signals aren't used currently by anything, but, they are  
tied to the PCM audio path on the bluetooth module, and likely will  
be similarly tied to PCM audio on our GSM boards once those happen.   
Both the bluetooth and GSM modules have an option to make the audio  
go another way (analog audio for GSM, or SCO-over-HCI for bluetooth),  
so you can use the NSSP for other stuff if you want to without  
running into any trouble.
