[j-nsp] m7i and tunnel pic

The way I understand it is that:
The chip that supplies the TP functionality (have you ever looked at  
an actual Tunnel Services PIC? There is basically nothing on it --  
the first time I saw it I figured it was a non-working engineering  
sample!) is built on the midplane and shows up as 1/2. When the ASM  
is plugged in (which is actually a full blown AS PIC without the  
casing), the tunnel chip is deactivated.

I have pulled an ASM out, screwed it into the housing that held a GE  
board and it ran fine.....
