ILEC - Incumbent Local Exchange Carrier


When the FCC deregulated the local exchange market in the Telecommunications Act of 1996, the existing local exchange carriers became known as the Incumbent local exchange carriers (ILECs). ILECs are entities that hold a certificate of convenience and necessity (CCN) as of September 01, 1975.

Who Should File: Any entity that held a CCN as of September 01, 1975 and is providing local exchange telephone service, basic local telecommunications service, or switched access service to customers besides itself. Any entity that currently holds a CCN and requests amendments to its existing certification.

When to File: PURA (Public Utility Regulatory Act) Chapter 54, Subchapter B., §54.053 (New or Amendment). The PUCT must grant or deny a New or Amendment CCN filing within one year of the date of the filing, unless good cause is shown for exceeding one year.
