a cable node has a capability of 1000-1500 users, the line is divided into 6mhz frequencies, some for tv, others for data traffic, upstream data trafic is in 2 mhz frequencies, so you are right about the upstream. the main difference is dsl requires fiber closer and closer to the home, and a big fat oc line close to the co ring ( sometimes an advanced sonet ring) to gain speeds, cable can simply open up more frequencies for data (each 6mhz frequencie can now carry upto 45mbps per second, there is firware in each node hub station that regulates this so noone can get over a specified amount, much like dsl capps. the funiest part of all this, is that sbc,verizon and other telcos who have many data centers and large robust backbones could already get your dsl line up to 9500 kbps (within 5500-7500 feet) verizon wont be upgrading its speeds even on fios for lower paying cust until the merger with mci goes through, unless they can wrk out the whole lease ip structure, much like sbc/at&t. at&t business class dsl already is @ 6-8mps through covads dslam and local sonet delivery option. heres a quick link to how a cable deleviry system works try searxhing some other options as well you can find info on how the dslam is integreted local fiber ring and xfrd to oc backbones and how exaclty these companies are doing all this I could go on for hours!!!

Not on a cable system. Cable systems have 5mbps to share with 100-2,000 people. COX has 700 people per node so they have to share 5mbps with them. If 2 people get the 15/2 for only $55/month and use it a lot there will only be 1mbps left to go around. Upload bandwidth is the problem with cable companies. You really have to consider the technology behind this. FIOS is a far superior more robust technology. The current FIOS network shares 622mbps with 16 to 32 users but it will be upgraded to 1000-2000mbps within a year. Fiber is the future but I do applaud COX for giving out every bit of bandwidth for a reasonable price (even if it's still $10 more expensive than FIOS). It's a good price / deal for people that don't have FIOS available to them.
