[TriLUG] Broadband Speeds

Quite right Jeremy. The upstream connection is the bottleneck point.
This is true be it from a Cable CMTS or a DSL DSLAM. The concern over
cable bandwidth sharing isn't really valid in the local loop these days.
Cable does have the potential of much higher speeds in the local loop
than say ADSL, but thats not saying much. VDSL is essentialy an OC-1
over twisted pair (without the redundancy of course). So why don't we
see lots of VDSL for sale? Well apart from distance limitations, and
the fact the few folks need that much bandwidth, the cost is too
prohibitive upstream. Local loops are cheap. Aggregated upstream loops
are expensive. Again, this is true for both Cable and DSL.
