I heard DSL is cool. DSL (Digital Subscriber Line) is an always-on internet connection that normally terminates in a socket on your wall, one that looks much like a phone socket. In the US, the socket is exactly a phone socket, and, for the popular residential DSL, (ADSL), the same housewiring does indeed carry both phone and data.
DSL is a general term to refer the technology but we commonly used ADSL and ADSL2+ for broadband access. DSL is also there in use as a corporate VPN access method, where users need equal bandwidth for upload and download.
