Traditionally, the local loop was an [[Wirelineelectrical (networking)|wirelinecircuit]] incarried natureby froma customersingle to[[twisted centralpair]] office,of specificallywires inwhich connected the formtelephone ofon anthe [[electricalcustomer's circuit]]premises (i.e.to [[wiktionary:loop|loop]])the provisioned as a singlelocal [[twistedtelephone pairexchange]]. inIn support of voice communications.older systems, Wherewhere the number of local loops was restricted, different customers could share the same loop, known as a [[party line (telephony)|party line]].

Modern implementations may include a [[digital loop carrier]] system segment or [[fiber optic]] transmission system known as [[fiber-in-the-loop]]. The local loop may terminate at a circuit switch owned by a [[competitive local exchange carrier]] and housed in a [[point of presence]] (POP), which typically is either an incumbent local exchange carrier telephone exchange or a "[[carrier hotel]]". A local loop may be provisioned to support data communications applications, or combined voice and data:
