In [[telephony]], the '''local loop''' (also referred to as the '''local tail''', '''subscriber line''', or in the aggregate as the [[last mile]]) is the physical link or circuit that connects from the [[demarcation point]] of the [[Customer-premises equipment|customer premises]] to the edge of the [[common carrier]] or [[telecommunications service provider]]'s network.

At the edge of the carrier [[access network]] in a traditional public telephone network, the local loop terminates in a circuit switch housed in an incumbent [[local exchange carrier]] or [[telephone exchange]].

* variants of [[digital subscriber line]] (DSL).

The term "local loop" is sometimes used for any "[[Last mile (telecommunications)|last mile]]" connection to the customer, regardless of technology or intended purpose. Local loop interrelations in this sense include:

*Electric power lines.

*Cable connections used with television, internet and telephone.

*Wireless signals or local loop (WLL): [[Local Multipointmultipoint Distributiondistribution Serviceservice|LMDS]], [[WiMAX]], [[GPRS]], [[HSDPA]], [[DECT]]

*Satellite connections for beamed signal.

*Optical or fiber optics services such as [[FiOS]].
