The DSL tech they sent to my house didn't even know what a DSLAM was! "Oh the node can't be over-sold, DSL is dedicated" he said.... and I said "Yeah, up until it hits the DSLAM, then it has a connection to the internet and maybe that needs to be upped". He proceeded to look at me puzzled and then ask "What is a DSLAM?".
When he asked "what is a DSLAM", you should have said "it is a move performed by wrestlers in the WWE." -- Satan is always busy. He makes bad things look good and good things look bad! Watch that Devil.
