I know full well what it is.

I do this for a living.

Did you know that more than half of small/medium businesses still get internet access over more traditional means (DSL, cable,dial-up)?

The rest get Metro Ethernet/T# pipes.

The profit margins for AT&T and other carriers on a 'business DSL' plan is staggering.

Same for cable.

Believe it or not..... a T1 circuit now had some substantial profit margins....

The point is, the last mile connection is actually dirt cheap for the carriers in most situations and it's the SAME last mile connection that you or I have in our homes, with the exception of Metro E and a T-carrier circuit.

All they have to do is meet that SLA..... and that's not hard nowadays.
