Editing Outside plant (section)

==Example: copper access network==
In civilian telecommunications, the copper [[access network]] (also known as the [[local loop]]) providing basic telephone or [[Digital subscriber line|DSL]] services typically consists of the following elements:<ref name="OPBE">{{cite web

*In-house wiring that connects [[customer premises equipment]] to the [[demarcation point]], usually in residential installations contained in a weather protected box.
*One or more [[twisted pair]]s, called a drop wire. The drop wires typically connect to a splice case, located in line for aerial cables, or in a small weather protected case for underground wiring, where the local cabling is connected to a secondary feeder line. These cables contain fifty or more twisted pairs.
*Secondary feeder lines run to a streetside cabinet containing a [[distribution frame]] called a [[Serving Area Interface]] (SAI).
*The [[Serving Area Interface|SAI]] is connected to the [[main distribution frame]], located at a [[Telephone exchange]] or other switching facility, by one or more primary feeder lines which contain hundreds of copper twisted pairs. An [[Serving Area Interface|SAI]] may also contain a [[Digital subscriber line access multiplexer]] (DSLAM) supporting [[Digital subscriber line|DSL]] service.

Active equipment (such as a [[Plain old telephone service|POTS]] or [[Digital subscriber line|DSL]] line circuit) can then be connected to the line in order to provide service, but this is not considered part of outside plant.
