When that market did not materialize it was recycled for Internet Access. VoD did not require much in the way of upload capacity.

Cable initially was a one way medium to deliver TV. In some facilities there was a modest back channel used for telemetry but it was way too slow for Internet. Some early Cable broadband implementations used dialup for upload, much like Satellite. Modern DOCSIS modems use frequencies below the lowest TV channel for upload. This capacity is at a premium and susceptible to foreign signal ingress.

Business plan for both DSL and Cable residential broadband assumed modest bursty usage. This means even though a given customer has very high peak rate average of all customers is low allowing ISP to minimize speed/cost of backhaul links and peering charges. This allows ISP to market services at very low cost.

As others have posted both Cablecos and Telcos want to market residential and business class service differently. Marketing is easier if technical aspects are different. Keep in mind regardless of speed business class service includes a Service Level Agreement (SLA) specifying performance and repair time. That said business class customer benefit from cheap residential broadband. Competition is driving down cost of business class service.

Thanks for the feedback...]]> http://www.dslreports.com/forum/remark,19976335 Mon, 11 Feb 2008 17:24:04 EDT http://www.dslreports.com/forum/remark,19976228 RockyBB : given that cable infrastructure is based on residential usage patterns, they don't want a lot of SMBs. they want the revenue, but not the traffic. that is why they don't offer more upload and why they don't guarantee anything. you don't have to be a genius to read between those lines...it should be loud and clear.

I am not sure why a cable company does not come along and offer more upload with some form of guarantees. Seems they could capture alot of SMBs.]]> http://www.dslreports.com/forum/remark,19976043 Mon, 11 Feb 2008 16:41:56 EDT http://www.dslreports.com/forum/remark,19975590 RockyBB : upload speeds are slow to prevent businesses from using residential pricing plans. residential services are shared resources ("best efforts connections" for sure), not dedicated connections. Business usage patterns on residential network topology could really screw up the financials.

Is it to keep T1s alive or is it a technical issue? Also, why do those have to be best effort connections? I get 8megs down and 512 up from Comcast for @50 bucks a month, but 1.5 both ways on Ts that cost 10 times more. If I could get a tad more upload I would consider losing my Ts. Of course no SLA would suck.

I guess it will be this way until fiber takes over. Which is taking way too long if you ask me.]]> http://www.dslreports.com/forum/remark,19974777 Mon, 11 Feb 2008 13:19:09 EDT
