ASP reports the modem model in my Lombard as "Spring".
On my MDD (FW800), it reports it as "Dash2".

So I guess those are the two kinds I was referring to. I would guess that the B&W will use the 'Spring' modem. Don't quote me, but I think its the one with the longer connector. The longer connector is about an inch long, the shorter one is more like a centimetre long.

Again, I hope I'm approaching something in the region of useful information here....
