Unbundling. An incumbent operator, owner of the local loop, has an obligation to provide pairs of copper wires to third-party operators, in exchange for compensation. Such third-party operators install their own transmission equipment in order to connect their networks to their customers’ premises. Partial unbundling allows a third-party operator to take over the internet connection while the incumbent operator still provides telephony subscription and services. Full unbundling allows a third-party operator to connect the entire customer line to its own network, and thus to offer both telephony and broadband services. USF. Universal Service Fund.
