ILEC: Incumbent Local Exchange Carrier
Incumbent Local Exchange Carrier (ILEC) is a telephone company that was providing local service when the Telecommunications Act of 1996 was enacted. Compare with CLEC, a company that competes with the already-established local telephone business. In most part of the world, ILECs are the Post, Telephone, and Telegraphs (PTTs), government-managed monopolies.
