I have to admit, we've been using PM3s since they supported CT1, and I
always thought that each DSO channel was bound to a specific Sx. I
completely understand that the modems are assigned from the pool, but this
part I didn't know and frankly I have evidence to the contrary.

I can tell when channels are turned up on our CT1 by doing a "show all" and
seeing byte traffic on the newly enabled channels. Any unused channels on
the CT1 always have zero bytes. This is completely reliable.

Am I just drawing the wrong conclusion from the data?
