OSI interface...

I'm using OSI version 9.0 with solaries OS , I 'm thinking of analysing the tracing while sending information through OSI layers , I want to analyze exactly the BER data ? Any one could provide an examples , I know the command for tracing these information but i need to understand the bytes travels through this layer ,, any document rather than admin document in SUN docs !!!

Thanks,
Atiato:)
