DSL - Section 3

More detail.. DSL[2] (Digital Subscriber Line) is a generic name for a family of standards allowing high speed data transfer over telephone lines (POTS), otherwise known as twisted pair. For carrying IP, DSL competes with cable modems, satellite digital data feeds, wireless digital data, ISDN, 56k modems and more expensive frame-relay lines etc.
Since the twisted pair lines used in the telephone network that are to carry DSL are not shielded from interference, there are limits on the distance DSL signals can travel before degrading the maximum DSL speeds available in all DSL standards.
This distance limitation of DSL is only one of many potential technical hurdles to pass before an installation is complete.

family of standards

HDSL, SDSL, ADSL, VDSL comprise the main DSL standards. Strictly speaking, the acronym DSL is actually an early low speed standard, and the 4 letter DSL acronyms are the standards in use today, but DSL has become a blanket term for all these technologies. Recently, the internation standards union settled on one consumer standard for DSL, called G.lite, also known as ADSL lite.
