"DSL is a dedicated service technology. If a 1.5 Mb/s service is offered by your phone company, you have 1.5 Mb/s dedicated to your line, guaranteed availability at that speed. Cable modem technology, on the other hand, is a shared service and as usage in the network goes up, the speed goes down."
DenverTechie,
I have another more straight forward question to ask, if you don't mind. I've always wondered about this and now is my chance to finally get an answer.
I think we've all experienced times when we go to make a voice call and we get a message saying, "Sorry. All circuits are busy. Please call again later." I read something like, if 30% of my neighbors made a call at the same time, I wouldn't be able to. If 30% signed up for 24x7 xDSL service, wouldn't we overwhelm the local CO? So if xDSL is a 24x7 service, then how can it be dedicated and guaranteed?
I believe you may say, "xDSL It's a packet-switched service so it won't overwhelm the local CO." But if it is, then it's not really, "dedicated" as in a true "dedicated" POTS circuit-switched voice connection.
What am I missing?
Thanks,
