Trying to avoid local loop charges? Good luck …

Local loop is the physical link (cicuit), that connects from the demarcation point of the customer premises to the edge of the telecommunications service provider network. At the edge of the carrier network in a traditional Public Switched Telephone Network (PSTN) scenario, the local loop terminates in a circuit switch housed in an ILEC (Incumbent Local Exchange Carrier) CO (Central Office). Traditionally, the local loop was wireline in nature from customer to central office, specifically in the form of an electrical circuit (i.e., loop) provisioned as a single twisted pair in support of voice communications. However, modern implementations may include a digital loop carrier system segment or fiber optic transmission system known as fiber-in-the-loop.

A local loop may be provisioned to support data communications applications, or combined voice and data such as digital subscriber line (DSL).

Local loop connections can be used to carry a range of services, including:

* analog voice and signaling used in traditional POTS
* Integrated Services Digital Network (ISDN)
* variants of Digital Subscriber Line (DSL)

Making the local loop available, usually by law, to the owner’s competitors, is referred to as local loop unbundling. However, local bells still charge an arm and a leg for this an there is practically no way to avoid this charges.
