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.....
