Oh, don't get me wrong. You're right that TWC has lots of capacity in the area, fiber-wise. It's the cable modem termination systems (CMTSes) that are the bottleneck. Basically, they can only handle n subscribers per downstream, and those get divvied up per upstream. They have to manage those pretty tightly, lest they oversubscribe a card on a CMTS. When one does get oversubscribed, they have to do a node split to redistribute. This means that they have to have additional capacity on another card to which they can move customers. That means downtime in order to complete the node split, and especially since introducing the VoIP services cable companies are very reluctant to do node splits. At this point, if TWC were to offer 20x2M bandwidth, they would have to do so many node splits, put in to many CMTSes (especially in concentrated areas like the Cary/Morrisville/Apex drop) that they would have a significant net negative, with significantly more capacity required to accommodate the subscriber growth that it would be far too expensive to consider. So the capacity is there in terms of fiber, but the pipe isn't the only piece of infrastructure to consider.

I really think this is all about competition. No matter what the growth (and TWC does have a LOT of capacity in this area in general), the thing that will cause the fastest bump in speeds is another player, like FiOS. In RR areas that also have FiOS, check out the speeds that are offered! Take a look at the following example: http://tampabay.mybrighthouse.com/products_and_pricing/internet/compare_plans/default.aspx The *only* reason they offer 15Mb/sec downstream is because of the legacy GTE, now Verizon FiOS availability. Unfortunately I think Verizon is too stupid to push FiOS here. I live in a brand new neighborhood on the edge of Morrisville/RTP. We're one of the few areas in Wake county that doesn't have Bellsouth, we have Verizon. Even though its a very nice, new neighborhood, nearly every home has at least one person working RTP (tech/pharma), they are sitting on GooGobs of fiber because of the proximity to RTP and we STILL didn't get FiOS! Incredibly lame because I think they were pushing for a complete triple play (voice, internet and video). They couldn't provide all 3 services and decided to go voice/DSL instead over copper. I called to get new phone service and was quoted a price so high, I was in shock. It was more than DOUBLE what I paid Bellsouth in NW Raleigh before we moved. So guess what I did? Triple play with TWC! One bill, 3 services. TWC dropped multiple fibers into the neighborhood, we have *lots* of capacity. Its all about competition. --OldSparcLuva On 1/23/07, Ben Pitzer <[EMAIL PROTECTED]> wrote: > Keep in mind that they have a small, probably underutilized network up > there, too.
