I've come to understand that in the Netherlands a 1:25 oversubscription
model is generally used between the CLEC's ATM network and the
private subscriber termination equipment run by each customer ISP.
Numbers for "business DSL" are more like 1:10.  Not all this traffic
will be off-net.

Of course, 640 kbps downstream is what we call "DSL Lite" here :)
