I am all confused right now. Telephone exchanges are connected for DSL with how much speed, 2Mbps, 4Mbps? Same goes for University these days which have been connected by HEC's project.
What I don't understand is that if the exchange is getting 2Mbps, how many users of say 2Mbps will that exchange support? If a user subscribes for a 2Mbps package, shouldn't that finish up all that 2Mbps which exchange is getting. This does sound silly I know but I want to know what exactly do they do that their exchange link is say 2Mbps and they can provide DSL to hundreds of users with good speed, including 2Mbps users. I know the share ratio thing exists but PTCL users have reported constant downloading speed most of the times.
This example fits on my brother's University as well. They have hooked the Uni up with 2Mbps. They get a constant download speed of 120-180 KB/s on the computers there. How is it possible? For a home user, 2Mpbs would result in a speed of 200+ KB/s, for a single computer downloading stuff. Why isn't it the same case with them?
