Which varies a lot from place to place.  First, because your DSL speed 
will be affected by the distance or the CO from your house, and by the 
quality of the wires.  On top of that, different carriers have different 
services.  For example, on top of various DSL packages, my telephone 
company offers fibre connections at 7, 10, 16 or 25 Mbps.  My Cable 
provider offers comparable packages as well.

Presumably?  Again.  After having been shown 4759483758975 times in this 
thread alone that your assumptions were wrong, you still persevere!!!
