====ATM and Frame Relay====
[[Asynchronous Transfer Mode]] (ATM) and [[Frame Relay]] are wide-area networking standards that can be used to provide Internet access directly<ref name="auto"/> or as building blocks of other access technologies. For example, many DSL implementations use an ATM layer over the low-level bitstream layer to enable a number of different technologies over the same link. Customer LANs are typically connected to an ATM switch or a Frame Relay node using leased lines at a wide range of data rates.<ref>[http://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-I.150-199902-I!!PDF-E&type=items ''B-ISDN asynchronous transfer mode functional characteristics''] {{webarchive|url=https://web.archive.org/web/20121012161801/http://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-I.150-199902-I!!PDF-E&type=items |date=2012-10-12 }}, ITU-T Recommendation I.150, February 1999, International Telecommunication Union</ref><ref>[http://searchenterprisewan.techtarget.com/definition/frame-relay "Frame Relay"] {{webarchive|url=https://web.archive.org/web/20120409171824/http://searchenterprisewan.techtarget.com/definition/frame-relay |date=2012-04-09 }}, Margaret Rouse, TechTarget, September 2005</ref>

While still widely used, with the advent of Ethernet over optical fiber, [[MPLS]], [[VPN]]s and broadband services such as cable modem and DSL, ATM and Frame Relay no longer play the prominent role they once did.
