It depends on how far the company chooses to run their lines. We are 45 miles away and get dsl just fine with our local company.

DSLAM
DSL (Digital Subscriber Line) is a type of internet connection that uses existing telephone lines to transmit data. Unlike cable internet, which shares bandwidth among multiple users in a neighborhood, DSL provides a dedicated line to each user, meaning that the speed and performance are not significantly impacted by the number of simultaneous users. However, the distance from the DSL modem to the service provider's central office can affect the connection quality and speed. Overall, DSL is more consistent in performance compared to shared broadband technologies.
the phone equipment (substation, etc) must be DSL compatible. If not, you can't get DSL. DSL is also limited to distance which is about 18,000 feet from the CO.
No, because the DSL (Digital Subscriber Line) is a technology of access to broadband internet through to connected copper cables that it takes the conventional telephone line, the disadvantage of this technology is that the line since the home or office until the Central telephone office not surpass 5.5 km.
1. Ther is no limit if we are using Optical Fiber DSL Connection 2. There is limit depend on number of nodes
I'm not certain how to answer the question (or why you're asking it), because I do know what DSL is.If you mean "how could a person chosen at random not know what DSL is" ... DSL is not important to most people in the world, so it's hardly surprising they'd have at best a vague idea of what it is. DSL is only useful to people who live a) close (in a network topology sense) to a central office and b) want a high-speed internet connection in both directions. Since most people are far more interested in download speed than upload speed, cable is likely to be at least as fast as DSL for the purposes they care about, and probably cheaper.
A fast Internet connection is a must-have for any office, and dial-up Internet is simply too outdated to be dependable and efficient. DSL and other high-speed Internet once came with a high monthly price tag but if you do your research, you can often find cheap DSL that is still fast and reliable.
