Local exchange carrier
The term local exchange carrier (LEC) is a regulatory term that was introduced by divestiture, the 1984 breakup of the Bell System. A LEC is a wireline communications company that services a local market. At divestiture, the 22 Bell Operating Companies (BOC) that were part of the Bell System were broken off and organized into seven Regional Bell Operating Companies (RBOC). The United States was broken in geographical areas called Local Access and Transport Areas (LATA). These LECs, also known as "Baby Bells," were limited to providing communications services within a LATA. Most of the U.S. received local phone services from these Baby Bells, but there are also many independent LECs that were not originally part of the Bell System.
