It's not the equivalent of broadband, it is broadband. :)
Cable, DSL, a Local Area Network, or if your lucky to have a direct connection to the internet itself (your own ISP) they're are all broadband connections. :)
DSL is probably the closest thing to a Direct Internet Connection. With DSL you have your dedicated, digitized line to the CO, and from there it goes into the DLSAM which is connected to OC48 SONET.
I WANT OC48 AT MY HOUSE!!!!! LOL
