Local loop unbundling (LLU or LLUB) is the regulatory process of allowing multiple telecommunications operators to use connections from a telephone exchange to the customer's location. The physical wire connection between the local exchange and the customer is known as a "local loop" and is owned by the incumbent local exchange carrier (also referred to as the "ILEC", "local exchange", or in the United States, either a "Baby Bell" or an independent telephone company). To increase competition, other providers are granted unbundled access.
