I'll make the official pronouncement blessing the Class B PSN mapping.
This is what BRL uses and this is what we've (DDN) specified for this
wierd thing called a concentrator.  As far as the class C mapping, 
the one cisco uses is as good as any.  I'd recommend you treat this as a
per network split, and set it up so you can use any amount of the bits
to represent host or packet switch.
