    I know this article is old but I must say it was very well written and you did a fantastic job explaining the difference to the layman.

    This is the way internet using cable works, not the way DSL works. With DSL each subscriber has a dedicated serice from there home to the DSlam. The distance between the subscriber and the DSlam effects the speed or rate the customer recieves, for instance a subscriber who is 20 meters may from the DSlam may get 12Mgb/s downstream while someone that is 3km away may get 6MGb/s. At the DSlam the DSL upstream ends (Downstream towards the subcriber starts) all the packets of information from each DSL line are sent to the internet over a highspeed facility today in most cases +1giga bit.

    Idk how many ways I can say your wrong about dsl it is a individual circuit from start to finish

      DSL tech – from the DSlam down individual circuits, above the DSlam, aggregated circuits.

    It is only an individual circuit to the dslam or asam. From there it is combined with the rest of the subscribers and slowdowns can and do occur due to traffic, like cable. The article is correct. 17 years telecom tech

    Dslams are fed by T1’s or Hdsl circuits for an adsl technology. So essentially the customer is sharing with other subscribers. The port out of the dslam and the pair to the home is separate but the lines feeding the dslam are not. Basically a dslam is a big router dividing up the main signals. Each port can be provisioned based on the service the customer has ordered. Even with VDSL customers share a fiber line. Granted fiber has a lot more bandwidth and the effects aren’t felt in most cases. The person who wrote this article is correct.

    One says this, and the other says the opposite. Now what am I supposed to believe? It’s almost like listening to the opposing political pundits in the TV media. I suppose I’ll have to find a more reliable source of information
